1. About this Guide

This guide covers the configuration of network devices in order to integrate them with PacketFence in VLAN enforcement. Switches, wireless controllers and wireless access points are all considered network devices in PacketFence’s terms.

The latest version of this guide is available at https://packetfence.org/documentation/

1.1. Other sources of information

2. Note on Inline enforcement support

There is no need to follow the instructions in this guide if you plan on deploying in inline enforcement, except RADIUS inline. In this case all you need to do is to have a flat layer 2 network up to PacketFence’s inline interface with no other gateway available for devices to reach out to the Internet.

This technique is usually used when your network hardware does not support VLAN enforcement.

3. Note on RADIUS accounting

Enabling RADIUS accounting on your network devices will significantly increase the database size and may cause performance issues. You should be aware of this and only use RADIUS accounting if it is really needed.

4. List of supported Network Devices

PacketFence supports a whole lot of different wireless and wired network equipment from various vendors running different versions. Since we want to provide the most accurate information and avoid duplication of that same information, please refer to our website https://packetfence.org/about.html#/material

You’ll find on this page the enforcement modes supported by each and every single piece of equipment we tested and worked with.

5. Switch configuration

5.1. Assumptions

Throughout this configuration example we use the following assumptions for our network infrastructure:

  • PacketFence is fully configured with FreeRADIUS running (if you want 802.1X or MAC Auth)
  • PacketFence IP address: 192.168.1.5
  • Normal VLAN: 1
  • Registration VLAN: 2
  • Isolation VLAN: 3
  • MAC Detection VLAN: 4
  • Guest VLAN: 5
  • VoIP, Voice VLAN: 100
  • use SNMP v2c
  • SNMP Read community: public
  • SNMP Write community: private
  • SNMP Trap community: public
  • RADIUS Secret: useStrongerSecret

5.2. 3COM

5.2.1. SuperStack 3 Switch 4200 and 4500

PacketFence supports these 3Com switches without VoIP using one trap type:

  • linkUp===linkDown
  • Port Security (with static MACs)

Don’t forget to update the startup config!

linkUp === linkDown only

Global config settings:

5.2.2. E4800G

PacketFence supports these 3Com switches with the following techniques:

  • 802.1X with MAC Authentication fallback
  • linkUp/linkDown (not recommended)

Voice over IP support was not explicitly tested during implementation however it does not mean that it won’t work.

Don’t forget to update the startup config!

linkUp / linkDown only

Global config settings:

5.2.4. NJ220

This switch does not support port-security.

To configure: use web interface to send the linkUp/linkDown traps to the PacketFence server.

5.3. Alcatel

5.3.1. OS6250, OS6450

PacketFence supports this switch using 802.1X, Mac authentication and also supports VoIP.

Global configuration

First define any VLAN that you want to use on the switch.

vlan 2
vlan 5
vlan 20
vlan 100

Next, configure the RADIUS server to be PacketFence

aaa radius-server "packetfence" host 192.168.1.5 key useStrongerSecret
aaa authentication mac packetfence
aaa authentication 802.1X packetfence

You now need to configure a user profile (equivalent of a role) that will determine which VLAN is assigned to the device. In this case the profile names are 'unreg', 'employee' and 'guest'.

aaa user-network-profile name unreg vlan 2
aaa user-network-profile name guest vlan 5
aaa user-network-profile name employee vlan 20

Next, configure the switch in PacketFence. In the case of this example, the uplink is port 1/1.

[192.168.1.10]
mode=production
description=alcatel
type=Alcatel
radiusSecret=useStrongerSecret
uplink_dynamic=0
uplink=1001
RoleMap=Y
VlanMap=N
registrationRole=unreg
isolationRole=unreg
defaultRole=employee
guestRole=guest
802.1X

First, make sure you followed the steps above in 'Global configuration'

You will need to configure the ports you want to do authentication on.

vlan port mobile 1/2
vlan port 1/2 802.1X enable
802.1X 1/2 supplicant policy authentication pass group-mobility block fail block
802.1X 1/2 non-supplicant policy authentication pass group-mobility block fail block
MAC Authentication

First, make sure you followed the steps above in 'Global configuration' and '802.1X'

Next configure the interface to bypass 802.1X authentication

802.1X 1/2 supplicant bypass enable
VoIP

PacketFence supports VoIP on Alcatel by having multiple devices using multiple untagged VLANs on the same port.

First configure the user profile for voice. In this example it is only isolating it on another VLAN but any user profile attributes can be added to the profile.

aaa user-network-profile name voice vlan 3

Next, make sure you enable VoIP in the switch configuration in PacketFence and configure the voiceRole.

[192.168.1.10]
VoIPEnabled=Y
voiceRole=voice

5.3.2. OS6860

PacketFence supports this switch using 802.1X, Mac authentication and also supports VoIP.

This documentation is made for Alcatel OS 8.1+. Lower versions do not support this configuration.
Global configuration

First define any VLAN that you want to use on the switch.

vlan 2 admin-state enable
vlan 5 admin-state enable
vlan 20 admin-state enable
vlan 100 admin-state enable

Next, configure the RADIUS server to be PacketFence

aaa radius-server "packetfence" host 192.168.1.5 key useStrongerSecret
aaa device-authentication mac packetfence
aaa device-authentication 802.1X packetfence

You now need to configure an edge profile (equivalent of a role) that will determine which VLAN is assigned to the device. In this case the profile names are 'unreg', 'employee' and 'guest'.

unp edge-profile unreg
unp edge-profile unreg redirect enable
unp edge-profile unreg authentication-flag enable
unp vlan-mapping edge-profile unreg vlan 2
unp edge-profile guest
unp edge-profile guest redirect enable
unp edge-profile guest authentication-flag enable
unp vlan-mapping edge-profile guest vlan 5
unp edge-profile employee
unp edge-profile employee redirect enable
unp edge-profile employee authentication-flag enable
unp vlan-mapping edge-profile employee vlan 20
Make sure you enable the redirect on all your roles as the access reevaluation will not work without it.

Next, configure the switch in PacketFence. In the case of this example, the uplink is port 1/1/1.

[192.168.1.10]
mode=production
description=alcatel
type=Alcatel
radiusSecret=useStrongerSecret
uplink_dynamic=0
uplink=1001
RoleMap=Y
VlanMap=N
registrationRole=unreg
isolationRole=unreg
defaultRole=employee
guestRole=guest
MAC Authentication

First, make sure you followed the steps above in 'Global configuration'

You will need to create an edge template and apply it on the ports you want to do authentication on.

unp edge-template pf_mab
unp edge-template pf_mab mac-authentication enable
unp edge-template pf_mab classification enable
unp port 1/1/2 port-type edge
unp port 1/1/2 edge-template pf_mab
802.1X

First, make sure you followed the steps above in 'Global configuration'

You will need to create an edge template and apply it on the ports you want to do authentication on.

unp edge-template pf_dot1x
unp edge-template pf_dot1x 802.1X-authentication enable
unp edge-template pf_dot1x mac-authentication enable
unp edge-template pf_dot1x 802.1X-authentication failure-policy mac-authentication
unp port 1/1/2 port-type edge
unp port 1/1/2 edge-template pf_dot1x
VoIP

PacketFence supports VoIP on Alcatel by having multiple devices using multiple untagged VLANs on the same port.

First configure the edge profile for voice. In this example it is only isolating it on another VLAN but any edge profile attributes can be added to the profile.

unp edge-profile voice
unp edge-profile voice redirect enable
unp edge-profile voice authentication-flag enable
unp vlan-mapping edge-profile voice vlan 100

Next, make sure you enable VoIP in the switch configuration in PacketFence and configure the voiceRole.

5.4. AlliedTelesis

5.4.1. AT8000GS

PacketFence supports the AT8000GS switch using :

  • MAC Authentication
  • 802.1X
  • 802.1X + VOIP
Assumptions
PacketFence management IP: 192.168.1.5
Switch management IP: 10.0.0.14
Guest VLAN (Internet): VLAN 1
MAC Authentication

First, enable 802.1X globally:

dot1x system-auth-control

Next, configure the RADIUS server and AAA settings:

radius-server host 192.168.1.5
radius-server key useStrongerSecret
radius-server source-ip 10.0.0.14
aaa authentication dot1x default radius
aaa accounting dot1x radius

In order to get mac authentication, you need to enable the guest VLAN globally:

interface vlan 1
name "Guest Vlan"
dot1x guest-vlan
exit

Finally, enable the necessary 802.1X settings for mac-only authentication:

interface ethernet g1
dot1x mac-authentication mac-only
dot1x radius-attributes vlan
dot1x port-control auto
dot1x guest-vlan enable
802.1X

The settings are almost the same as the MAC Authentication with some small differences.

First, enable 802.1X globally:

dot1x system-auth-control

Next, configure the RADIUS server and AAA settings:

radius-server host 192.168.1.5
radius-server key useStrongerSecret
radius-server source-ip 10.0.0.14
aaa authentication dot1x default radius
aaa accounting dot1x radius

Finally, enable the necessary 802.1X settings:

interface ethernet g1
dot1x radius-attributes vlan
dot1x port-control auto
802.1X + VOIP

First, enable 802.1X globally:

dot1x system-auth-control

Next, configure the RADIUS server configuration and AAA settings:

radius-server host 192.168.1.5
radius-server key useStrongerSecret
radius-server source-ip 10.0.0.14
aaa authentication dot1x default radius
aaa accounting dot1x radius

Then, LLDP configuration:

hostname switch-name
ip domain-name domain.local
lldp med network-policy 1 voice vlan 100 vlan-type tagged dscp 34
lldp med network-policy 2 voice-signaling vlan 100 vlan-type tagged dscp 34

Finally, enable the necessary 802.1X and VOIP settings on each interface:

interface ethernet g1
dot1x port-control force-authorized
no dot1x guest-vlan enable
no dot1x mac-authentication
no dot1x radius-attributes vlan
no dot1x re-authentication
switchport mode trunk
switchport trunk native vlan 5
switchport trunk allowed vlan add 100
lldp med enable network-policy
lldp med network-policy add 1
lldp med network-policy add 2
802.1X commands
show dot1x supplicant brief

5.4.2. GS950

PacketFence supports the GS950 switch using :

  • MAC Authentication
  • 802.1X (without fallback to MAC authentication)
Global configuration

First, ensure that the VLANs you want to assign are part of the VLAN database via the following page:

VLAN configuration

Note that they only need to be tagged on the trunk and don’t need any specific configuration for the dynamic VLAN assignment here.

Next, configure the RADIUS server (Security → RADIUS):

RADIUS configuration

Next, configure an SNMP community (SNMP → Community Table)

SNMP configuration
MAC authentication

Go in Security → Port Access Control, select the port you want to enable MAB on, and ensure you set:

  • Authentication Mode: MAC Based
  • Port Control: Auto
  • Supplicant Mode: Single
  • VLAN Assignment: Enabled
MAB config
802.1x

Go in Security → Port Access Control, select the port you want to enable MAB on, and ensure you set:

  • Authentication Mode: 802.1X
  • Port Control: Auto
  • Supplicant Mode: Multiple
  • VLAN Assignment: Enabled
802.1x configuration
PacketFence configuration

Ensure you configure at least:

  • Type: Allied Telesis GS950
  • RADIUS secret: useStrongerSecret
  • SNMP Version: v2c
  • SNMP Community Read: private
  • SNMP Community Write: private

If you are using MAC authentication on this switch, you must adjust the FreeRADIUS configuration so it transforms the EAP requests this switch sends into requests that PacketFence will interpret as MAC authentication. This configuration will also set missing attributes in the RADIUS requests since this switch doesn’t follow the standard attributes that are usually sent during RADIUS authentication.

To adjust it, go in /usr/local/pf/conf/radiusd/packetfence and add the following below the line that contains packetfence-eap-mac-policy:

packetfence-allied-gs950-mab

And then restart FreeRADIUS:

# /usr/local/pf/bin/pfcmd service radiusd restart

5.5. Amer

PacketFence supports Amer switches without VoIP using one trap type:

  • linkUp/linkDown

Don’t forget to update the startup config!

5.5.1. L2 Switch SS2R24i

Global config settings:

create snmp host 192.168.1.5 v2c public
create snmp user public ReadGroup
enable snmp traps

On each interface:

config vlan default delete xx
config vlan mac-detection add untagged xx

where xx stands for the interface index

5.6. Aruba

5.6.1. Aruba 2930M Serie

The Aruba 2930M is supported by PacketFence and it supports MAC Authentication, 802.1X, Dynamic ACLS and Web Authentication.

Global Radius Configuration
radius-server host 192.168.1.5 key "useStrongerSecret"
radius-server host 192.168.1.5 dyn-authorization
radius-server host 192.168.1.5 time-window 0

aaa port-access authenticator 1
aaa port-access authenticator 1 tx-period 10
aaa port-access authenticator 1 client-limit 2
aaa port-access authenticator active
Web Authentication
aaa authentication captive-portal enable

On the PacketFence side you will need to fill the "Role by Access List" for the registration role:

permit in tcp from any to 192.168.1.5 80
permit in tcp from any to 192.168.1.5 443
deny in tcp from any to any 80 cpy
deny in tcp from any to any 443 cpy
permit in udp from any to any 53
permit in udp from any to any 67

And the "Role by Web Auth URL" for the registration role:

http://192.168.1.5/Aruba::2930M
Dynamic ACL

The switch needs to be configure to do MAC Authentication and or 802.1x. Then on the PacketFence side in the switch roles, enable "Role by Access List" and fill the appropriate role with the acl you want.

5.7. Avaya

Avaya bought Nortel’s wired networks assets. So Avaya switches are, in effect, re-branded Nortels. See Nortel section of this document for configuration instructions.

5.7.1. 802.1X with MAC Authentication Bypass and VoIP

The configuration below requires an ntp server. We use the PacketFence server as the NTP server but any other one will do. If you want to use the PacketFence server for NTP, make sure you install the appropriate service and open port 123 in /usr/local/pf/conf/iptables.conf

Global config settings:

sntp server primary address 192.168.1.5

The configuration above enables authentication on port 1/1/1 - make sure you change this to the ports where you want to perform enforcement.

  • SNMP configuration
    snmpserver community public ro
    snmpserver community private rw
  • PacketFence configuration

While configuring the switch in PacketFence, ensure you set at least the following values: * Definition, Type: Brocade Switches * RADIUS, Secret Passphrase: useStrongerSecret * SNMP, Version: v2c * SNMP, Community Read: public * SNMP, Community Write: private

VoIP

In order to enable VoIP, you first need to enable LLDP then define the network policy for tagging VoIP traffic on the ports where PacketFence is enabled.

lldp run
lldp med network-policy application voice tagged vlan 5 priority 5 dscp 46 ports ethe 1/1/1
Make sure you change VLAN 5 to the VLAN you use for VoIP
  • PacketFence configuration

While configuring the switch in PacketFence, ensure you set at least the following values: * Roles, voice VLAN: 5 * Definition, VoIP: enabled

5.8.3. Radius CLI Login

If you want to use the server PacketFence to authenticate users on the Brocade switch.

  • Configure the radius server to send user authentication request to PacketFence
    aaa authentication login default radius local
Make sure to have a local account in case the switch can not reach the PacketFence server

5.9. Cisco

PacketFence supports Cisco switches with VoIP using three different trap types:

  • linkUp/linkDown
  • MAC Notification
  • Port Security (with static MACs)

You also need to make sure that lldp or cdp notification is configured on all ports that will handle VoIP.

On some recent models, we can also use more secure and robust features like:

  • MAC Authentication (Cisco’s MAC Authentication Bypass or MAB)
  • 802.1X (Multi-Host or Multi-Domain)

Depending of the switch model, we recommend the use of the most secure and reliable feature first. In other words, you should consider the following order:

  1. 802.1X/MAB

  2. Port-Security

  3. linkUp/linkDown

5.9.1. 2900XL / 3500XL Series

SNMP | linkUP/linkDown

Global config settings:

snmp-server community public RO
snmp-server community private RW

mac-address-table notification interval 0
mac-address-table notification

On each interface with VoIP:

switchport trunk encapsulation dot1q
switchport trunk native vlan 4
switchport mode trunk
switchport voice vlan 100
snmp trap mac-notification added
snmp trap mac-notification removed

5.9.2. 2950

Those switches are now supported using 802.1X for networks with or without VoIP. You can also use port-security with static MAC address but we can not secure a MAC on the data VLAN specifically so enable it if there is no VoIP, use linkUp/linkDown and MAC notification otherwise.So on setup that needs to handle VoIP with this switch, go with a 802.1X configuration.

802.1X

Make sure that you have a local account, because enabling 802.1X or MAB will ask for a username and password on the next login.

Port-Security
With port-security, if no MAC is connected on ports when activating port-security, we need to secure bogus MAC addresses on ports in order for the switch to send a trap when a new MAC appears on a port. On the other hand, if a MAC is actually connected when you enable port security, you must secure this MAC rather than the bogus one. Otherwise this MAC will lose its connectivity instantly.

Since version PacketFence 2.2.1, the way to handle VoIP when using port-security dramatically changed. Ensure that you follow the instructions below. To make the story short, instead on relying on the dynamic MAC learning for VoIP, we use a static entry on the voice VLAN so we can trigger a new security violation, and then authorize the phone MAC address on the network.

5.9.5. 2960, 2970, 3560, 3750

You shouldn’t use any port-security features when doing 802.1X and/or MAC Authentication. This can cause unexpected behavior.

Make sure that you have a local account, because enabling 802.1X or MAB will ask for a username and password on the next login.

When doing 802.1X and network interface teaming on the same switch or stack, you might consider using the mac-move feature of the Cisco switches. When you authenticate the primary link of the team, the virtual MAC address will be published and authorized on the switchport. When something breaks on that link (ie. cable disconnected), the teaming driver will publish the MAC address on the secondary link, and the switch will try to authorize it. However, since the switch already has the MAC address in a session on another switchport, the switch will put the secondary link into err-disabled mode.

To prevent this behavior, you need to tell the switch to allow MAC address movements between ports. The global command is the following:

authentication mac-move permit

Web auth

The Catalyst 2960 supports web authentication from IOS 12.2.55SE3. This procedure has been tested on IOS 15.0.2SE5.

In this example, the ACL that triggers the redirection to the portal for registration is 'registration'.

Configure the global configuration of the switch using the section MAC Authentication bypass only of the 2960 in this document.

Then add this additional configuration on the global level

ip device tracking
ip http server
ip http secure-server
snmp-server community public RO
snmp-server community private RW

Add the required access lists

ip access-list extended registration
deny ip any host <your captive portal ip>
permit tcp any any eq www
permit tcp any any eq 443

Then on each controlled interface

switchport access vlan <vlan>
switchport mode access
authentication priority mab
authentication port-control auto
authentication periodic
authentication violation replace
mab
spanning-tree portfast

PacketFence switch configuration

  • Select the type to 'Cisco Catalyst 2960'
  • Set the 'Registration' role to 'registration' (If left empty then it will use the role name)
  • Set Role by Web Auth URL for registration to 'http://<your_captive_portal_ip>/Cisco::Catalyst_2960'
  • The URL can contain dynamic parameters, like the MAC address ($mac), the switch IP ($switch_ip), the username ($user_name).
  • Screenshots of this configuration are available in the Cisco WLC section of this guide.
Downloadable ACLs

The Catalyst 2960 supports RADIUS pushed ACLs which means that you can define the ACLs centrally in PacketFence without configuring them in your switches and their rules will be applied to the switch during the authentication.

These ACLs are defined by role like the VLANs which means you can define different ACLs for your registration VLAN, production VLAN, guest VLAN, etc.

Add the following configuration setting on the global level

ip device tracking

For IOS 12.2, you need to create this acl and assign it to the switch port interface:

ip access-list extended Auth-Default-ACL
permit udp any range bootps 65347 any range bootpc 65348
permit udp any any range bootps 65347
permit udp any any eq domain
deny ip any any
interface GigabitEthernetx/y/z
...
ip access-group Auth-Default-ACL in
...

Before continuing, configure your switch to be in MAC authentication bypass or 802.1X.

Now in the PacketFence interface go in the switch configuration and in the Roles tab.

Check 'Role by access list' and you should now be able to configure the access lists as below.

For example if you want the users that are in the registration VLAN to only use HTTP, HTTPS, DNS and DHCP you can configure this ACL in the registration category.

Registration ACL

Now if for example, your normal users are placed in the 'default' category and your guests in the 'guest' category.

If for example the 'default' category uses the network 192.168.5.0/24 and your guest network uses the network 192.168.10.0/24.

You can prevent communications between both networks using these access lists

Cross network deny ACL

You could also only prevent your guest users from using shared directories

Deny shares ACL

Or also you could restrict your users to use only your DNS server where 192.168.5.2 is your DNS server

Force DNS ACL
Web auth and Downloadable ACLs

It’s possible to mix web authentication and downloadable ACLs starting from version 12.2 of the IOS, each roles can be configured to forward the device to the captive portal for an http or an https and only allow specific traffic with the ACL. To do that, you need to configure PacketFence with Role by Web Auth URL and with Role by access list (For each role you need). On the switch you need to change the Auth-Default-ACL to add the portal IP address:

For IOS 12.2:

ip access-list extended Auth-Default-ACL
permit udp any range bootps 65347 any range bootpc 65348
permit udp any any range bootps 65347
permit ip any host ip_of_the_captive_portal
permit udp any any eq domain
deny ip any any

And assign this ACL on the switch port yo want to do ACL per port.

interface GigabitEthernetx/y/z
...
ip access-group Auth-Default-ACL in
...

For IOS 15.0:

Extended IP access list Auth-Default-ACL
10 permit udp any range bootps 65347 any range bootpc 65348
20 permit udp any any range bootps 65347
30 deny ip any any
conf t
ip access-list extend Auth-Default-ACL
21 permit ip any host ip_of_the_captive_portal

For IOS 15.2:

Extended IP access list Auth-Default-ACL
10 permit udp any any eq domain
20 permit tcp any any eq domain
30 permit udp any eq bootps any
40 permit udp any any eq bootpc
50 permit udp any eq bootpc any
60 deny ip any any
conf t
ip access-list extend Auth-Default-ACL
51 permit ip any host ip_of_the_captive_portal

5.9.6. Stacked 29xx, Stacked 35xx, Stacked 3750, 4500 Series, 6500 Series

The 4500 Series and all the stacked switches work exactly the same way as if they were not stacked so the configuration is the same: they support port-security with static MAC address and allow us to secure a MAC on the data VLAN so we enable it whether there is VoIP or not.

We need to secure bogus MAC addresses on ports in order for the switch to send a trap when a new MAC appears on a port.

  • Select the type to 'Cisco Catalyst 2960'
  • Set the 'Registration' role to 'registration' (If left empty then it will use the role name)
  • Set Role by Web Auth URL for registration to 'http://<your_captive_portal_ip>/Cisco::Catalyst_2960'
  • The URL can contain dynamic parameters, like the MAC address ($mac), the switch IP ($switch_ip), the username ($user_name).
  • Screenshots of this configuration are available in the Cisco WLC section of this guide.
AAA authentication is slow to come up after a reload of the IOS XE switches. This makes the recovery from a reboot longer to complete. This is due to a bug in IOS XE. A workaround is to execute the following command no aaa accounting system default start-stop group tacacs+.
Identity Networking Policy

Starting from version 15.2(1)E (IOS) and 3.4.0E (IOSXE) , Cisco introduced the Identity Based Networking Services. It means that you can create an authentication workflow on the switch and create interfaces templates.

DHCP Option 82

In order to enable the DHCP Option 82, you need to add the following parameters. Let’s say you want to enable it for the vlan 1 to 1024:

ip dhcp snooping
ip dhcp snooping vlan 1-1024

On uplink interfaces:

ip dhcp snooping trust
Router ISR 1800 Series

PacketFence supports the 1800 series Router with linkUp / linkDown traps. It cannot do anything about the router interfaces (ie: fa0 and fa1 on a 1811). VLAN interfaces ifIndex should also be marked as uplinks in the PacketFence switch configuration as they generate traps but are of no interest to PacketFence (layer 3).

Global config settings:

snmp-server enable traps snmp linkdown linkup
snmp-server host 192.168.1.5 trap version 2c public

On each interface:

switchport mode access
switchport access vlan 4

5.9.8. EAP-FAST authentication Support

PacketFence supports Cisco NEAT through EAP-MD5, EAP-FAST, EAP-GTC and EAP-MSCHAPv2 authentication methods. Upon successful authentication against PacketFence, the authenticator switch will give trunk access to the supplicant switch.

Here is an official Cisco guide, from which the following configuration derives: https://www.cisco.com/c/en/us/support/docs/lan-switching/8021x/116681-config-neat-cise-00.html

The following configuration example contains required changes to be applied on both authenticator and supplicant switches to provide EAP-FAST authentication against PacketFence.

Authenticator

Global settings:

aaa group server radius packetfence
server 192.168.1.5 auth-port 1812 acct-port 1813
aaa authentication dot1x default group packetfence
aaa authorization network default group packetfence
cisp enable

Uplink configuration:

interface FastEthernet0/20
switchport mode access
authentication port-control auto
dot1x pae authenticator
Supplicant

Global settings (replace username and password):

cisp enable
eap profile EAP_PRO
method fast
dot1x credentials EAP_PRO
username switches
password 7 03174C02120C29495D
! Password is switches
!
dot1x supplicant force-multicast

Uplink settings:

interface GigabitEthernet1/0/24
switchport mode trunk
dot1x pae supplicant
dot1x credentials EAP_PRO
dot1x supplicant eap profile EAP_PRO

5.9.9. Device Sensor for Cisco Equipment

Device sensor is a way to be able to receive some information about endpoints from the RADIUS accounting packet. (like DHCP, CDP, LLDP and HTTP information) In order to enable Device Sensor feature, you need to add the following parameters to your switch configuration:

radius server packetfence
address ipv4 192.168.1.5 auth-port 1812 acct-port 1813
key useStrongerSecret
aaa group server radius packetfence
server name packetfence
!
aaa accounting update newinfo
aaa accounting identity default start-stop group packetfence
!
!
device-sensor filter-list dhcp list dhcp-list
option name host-name
option name parameter-request-list
option name class-identifier
!
device-sensor filter-list lldp list lldp-list
tlv name system-description
!
device-sensor filter-list cdp list cdp-list
tlv name version-type
tlv name platform-type
!
device-sensor filter-list dhcp list lldp-list
device-sensor filter-spec dhcp include list dhcp-list
device-sensor filter-spec lldp include list lldp-list
device-sensor filter-spec cdp include list cdp-list
device-sensor notify all-changes

This configuration will make the switch send information about DHCP, LLDP and CDP of the endpoint in the RADIUS accounting packets.

5.10. Cisco Small Business (SMB)

The Cisco Small Business switches support MAC based authentication (MAB) as well as 802.1X and VoIP. Both technologies can be combined and will work correctly together on the same switchport.

Nothing is required to activate VoIP on the switch, you must simply configure the voice VLAN you want PacketFence to assign in the PacketFence switch configuration as well as enabling VoIP there. Note that your phones must not tag their packets on the network and should send their traffic untagged when connected into a PacketFence enabled port. This means you should not have the voice VLAN capabilities enabled on the switch itself as they might conflict with the authorization attributes returned by PacketFence.

5.10.1. Global configuration

Before executing these steps, make sure you have a local account configured to login on the switch or are pointing to a RADIUS server for management. Otherwise, you will not be able to login into the switch anymore.

You must first define your RADIUS server and point it to PacketFence:

dot1x system-auth-control
radius-server key useStrongerSecret
radius-server host 192.168.1.5
aaa accounting dot1x start-stop group radius
snmp-server community public ro view Default
snmp-server community private rw view Default

SNMP configuration for the Cisco SG300:

snmp-server community public ro view DefaultSuper
snmp-server community private rw view DefaultSuper

5.10.2. MAC Authentication

In order to configure MAC authentication, you must enable it on each interface

interface x/y/z
dot1x host-mode multi-sessions
dot1x reauthentication
dot1x timeout reauth-period 10800
dot1x timeout quiet-period 10
dot1x timeout server-timeout 5
dot1x timeout supp-timeout 3
dot1x authentication mac
dot1x radius-attributes vlan
dot1x port-control auto
spanning-tree portfast
switchport mode general
switchport general pvid 2

5.10.3. 802.1X with MAB

In order to configure 802.1X with a fall-back to MAC authentication, you must enable it on each interface

interface x/y/z
dot1x host-mode multi-sessions
dot1x reauthentication
dot1x timeout quiet-period 10
dot1x timeout server-timeout 5
dot1x timeout supp-timeout 3
dot1x authentication dot1x mac
dot1x radius-attributes vlan
dot1x port-control auto
spanning-tree portfast
switchport mode general
switchport general pvid 2

Once you have configured your switchports, you must configure the switch in PacketFence with the following information:

  • Definition → Type: Cisco SG500
  • Definition → Mode: production
  • Definition → Deauthentication Method: SNMP
  • Definition → VoIP enabled if you need VoIP on this switch.
  • Roles → voice VLAN set to the VLAN you want to assign to the VoIP devices connecting to this switch.
  • RADIUS → Secret Passphrase: useStrongerSecret
  • SNMP → Version: v2c
  • SNMP → Community Read: public
  • SNMP → Community Write: private

5.10.4. 802.1X commands

show dot1x
show dot1x users

PacketFence supports D-Link switches without VoIP using two different trap types:

  • linkUp/linkDown
  • MAC Notification

We recommend to enable linkUp/linkDown and MAC notification together.

Don’t forget to update the startup config!

config mac_based_access_control ports 1:1 mode host_based

5.12. Dell

When doing MAC Authentication, there is a known issue with some Dell switches. If you get errors where the device is using EAP type MD5, but PacketFence is expecting PEAP, you will need to edit the line default_eap_type = peap under the section eap in the file /usr/local/pf/conf/radiusd/eap.conf to default_eap_type = md5.

5.14. Enterasys

PacketFence supports Enterasys switches without VoIP using two different trap types:

  • linkUp/linkDown
  • MAC Locking (Port Security with static MACs)

We recommend to enable MAC locking only.

Don’t forget to update the startup config!

5.14.1. Matrix N3

linkUp/linkDown traps are enabled by default so we disable them and enable MAC locking only. Also, by default this switch doesn’t do an electrical low-level linkDown when setting the port to admin down. So we need to activate a global option called forcelinkdown to enable this behavior. Without this option, clients don’t understand that they lost their connection and they never do a new DHCP on VLAN change.

Global config settings

set snmp community public
set snmp targetparams v2cPF user public security-model v2c message-processing v2c
set snmp notify entryPF tag TrapPF
set snmp targetaddr tr 192.168.1.5 param v2cPF taglist TrapPF
set maclock enable
set forcelinkdown enable

On each interface:

set port trap ge.1.xx disable
set maclock enable ge.1.xx
set maclock static ge.1.xx 1
set maclock firstarrival ge.1.xx 0
set maclock trap ge.1.xx enable

where xx stands for the interface index.

5.14.2. SecureStack C2

linkUp/linkDown traps are enabled by default so we disable them and enable MAC locking only.

Global config settings

set snmp community public
set snmp targetparams v2cPF user public security-model v2c message-processing v2c
set snmp notify entryPF tag TrapPF
set snmp targetaddr tr 192.168.1.5 param v2cPF taglist TrapPF
set maclock enable

On each interface:

set port trap fe.1.xx disable
set maclock enable fe.1.xx
set maclock static fe.1.xx 1
set maclock firstarrival fe.1.xx 0

where xx stands for the interface index

5.14.3. SecureStack C3

This switch has the particular feature of allowing more than one untagged egress VLAN per port. This means that you must add all the VLAN created for PacketFence as untagged egress VLAN on the relevant interfaces. This is why there is a VLAN command on each interface below.

linkUp/linkDown traps are enabled by default so we disable them and enable MAC locking only.

Global config settings

set snmp community public
set snmp targetparams v2cPF user public security-model v2c message-processing v2c
set snmp notify entryPF tag TrapPF
set snmp targetaddr tr 192.168.1.5 param v2cPF taglist TrapPF
set maclock enable

On each interface:

set vlan egress 1,2,3 ge.1.xx untagged
set port trap ge.1.xx disable
set maclock enable ge.1.xx
set maclock static ge.1.xx 1
set maclock firstarrival ge.1.xx 0
set maclock trap ge.1.xx enable

where xx stands for the interface index

5.14.4. Standalone D2

linkUp/linkDown traps are enabled by default so we disable them and enable MAC locking only.

This switch Switch accepts multiple untagged VLAN per port when configured through SNMP. This is problematic because on some occasions the untagged VLAN port list can become inconsistent with the switch’s running config. To fix that, clear all untagged VLANs of a port even if the CLI interface doesn’t show them. To do so, use: clear vlan egress <vlans> <ports>

Global config settings

set snmp community public
set snmp targetparams v2cPF user public security-model v2c message-processing v2c
set snmp notify entryPF tag TrapPF
set snmp targetaddr tr 192.168.1.5 param v2cPF taglist TrapPF
set maclock enable

On each interface:

set port trap ge.1.xx disable
set maclock enable ge.1.xx
set maclock static ge.1.xx 1
set maclock firstarrival ge.1.xx 0
set maclock trap ge.1.xx enable

where xx stands for the interface index

5.15. Extreme Networks

PacketFence supports Extreme Networks switches using:

  • linkUp/linkDown
  • MAC Address Lockdown (Port Security)
  • Netlogin - MAC Authentication
  • Netlogin - 802.1X
  • Netlogin - web authentication
  • RADIUS authentication for CLI access

Don’t forget to save the configuration!

5.15.1. All Extreme XOS based switches

In addition to the SNMP and VLANs settings, this switch needs the Web Services to be enabled and an administrative username and password provided in its PacketFence configuration for Web Services.

MAC Address Lockdown (Port-Security)

linkUp/linkDown traps are enabled by default so we disable them and enable MAC Address Lockdown only.

Global config settings without Voice over IP (VoIP):

5.15.2. MAC Authentication + 802.1x

You can mix the MAC Authentication and 802.1X on the same switchport. If the device fails 802.1X authentication, it will fallback to the MAC Authentication. Configure the MAC Authentication and 802.1x like the section above and add this extra command:

enable netlogin ports 1-48 dot1x mac
Policy based access

You can assign policies defined on the switch via PacketFence.

First define your policy in the switch:

configure policy profile 1 name "gaming" pvid-status "enable" pvid 3521 untagged-vlans 3521
configure policy profile 2 name "guest" pvid-status "enable" pvid 3522 untagged-vlans 3522
configure policy maptable response both
configure policy vlanauthorization enable

Next, in PacketFence, enable 'Role by Switch Role' in your switch configuration and assign the policies to the roles there. They will be returned inside the Filter-Id attribute.

Make sure you use the 'Extreme EXOS' type for your switch to use this feature.

5.16. Foundry

5.16.1. FastIron 4802

PacketFence support this switch with optional VoIP using two different trap types:

  • linkUp/linkDown
  • Port Security (with static MACs)

We recommend to enable Port Security only.

Don’t forget to update the startup config!

Those switches support port-security with static MAC address and allow us to secure a MAC on the data VLAN so we enable it whether there is VoIP or not.

We need to secure bogus MAC addresses on ports in order for the switch to send a trap when a new MAC appears on a port.

Global config settings

snmp-server host 192.168.1.5 public
no snmp-server enable traps link-down
no snmp-server enable traps link-up

On each interface without VoIP:

int eth xx
port security

maximum 1
secure 0200.0000.00xx 0

where xx stands for the interface ifIndex.

With VoIP a little more work needs to be performed. Instead of the no-VoIP, put in the following config:

conf t

5.18. HP

5.18.1. HPE 1910 Serie

The HP 1910 Serie is based on the 3Com OS and most of the configuration will be done from the GUI.

VLAN creation: * go to Network, VLAN, * click on the Create tab * create the VLANs

Configure PacketFence as a RADIUS server: * go to Authentication, RADIUS * click on the RADIUS Server tab * from Server Type, select Authentication Server * from Primary Server, give the PacketFence IP address * click Apply

Then: * click on the RADIUS Setup tab * check the box Authentication Server Shared Key * give the shared key * from Username Format, select without-domain * click Apply

Create a new authentication domain: * go to Authentication, AAA, * click on the Domain Setup tab,

We will need to create a specific authentication domain and not making it as the default domain.

Configure the 802.1X and authentication method: * go to Authentication * click on the 802.1X tab * check the Enable 802.1X box * from Authentication Method, select EAP

Configure the authentication domain:

INFO: Even limited, there is a command line access.

  • connect to the switch using ss,
  • type the command:
    _cmdline-mode on
  • password is: 512900
  • Type the commands:
    System-view
    Mac-authentication domain YOUR_DOMAIN_NAME
    Mac-authentication user-name-format mac-address with-hyphen
  • change the YOUR_DOMAIN_NAME with the one from your environment
  • do not close your terminal, we will come back to this later
  • from the GUI, go to Authentication, 802.1X
  • from Port, select the port your are connected to. GigabitEthernet X/X/X
  • from Port Control, select MAC Based
  • from Max Number of Users, give 2
  • check the box Enable Re-Authentication

5.18.2. E4800G and E5500G Switch series

These are re-branded 3Com switches, see under the 3Com section for their documentation.

5.19. HP ProCurve

PacketFence supports ProCurve switches without VoIP using two different trap types:

  • linkUp/linkDown
  • Port Security (with static MACs)

We recommend to enable Port Security only.

Don’t forget to update the startup config!

HP ProCurve only sends one security trap to PacketFence per security violation so make sure PacketFence runs when you configure port-security. Also, because of the above limitation, it is considered good practice to reset the intrusion flag as a first troubleshooting step.

If you want to learn more about intrusion flag and port-security, please refer to the ProCurve documentation.

If you configure a switch that is already in production be careful that enabling port-security causes active MAC addresses to be automatically added to the intrusion list without a security trap sent to PacketFence. This is undesired because PacketFence will not be notified that it needs to configure the port. As a work-around, unplug clients before activating port-security or remove the intrusion flag after you enabled port-security with: port-security <port> clear-intrusion-flag.

5.19.1. 2500 Series

linkUp/linkDown traps are enabled by default so we disable them and enable Port Security only.

On 2500’s, we need to secure bogus MAC addresses on ports in order for the switch to send a trap when a new MAC appears on a port.

Global config settings:

snmp-server community "public" Unrestricted
snmp-server host 192.168.1.5 "public" Not-INFO
no snmp-server enable traps link-change 1-26

On each interface:

port-security xx learn-mode static action send-alarm mac-address 0200000000xx

where xx stands for the interface index

CLI authentication

You can use PacketFence for RADIUS CLI authentication on the 2500 Series.

Global config settings

radius-server host 192.168.1.5 key useStrongerSecret
aaa authentication ssh login radius local
aaa authentication telnet login radius local

Next, make sure you configure the switch in PacketFence accordingly as well as the proper administrative access. Refer to the Administration Guide for more details.

5.19.2. 2600 Series and 3400cl Series

Port-Security

linkUp/linkDown traps are enabled by default so we disable them and enable Port Security only.

On 2600’s, we don’t need to secure bogus MAC addresses on ports in order for the switch to send a trap when a new MAC appears on a port.

Global config settings

snmp-server community public manager unrestricted
snmp-server host 192.168.1.5 "public" Not-INFO
no snmp-server enable traps link-change 1-26

On each interface:

port-security xx learn-mode configured action send-alarm

where xx stands for the interface index

MAC Authentication (Firmware > 11.72)

In order to enable RADIUS mac authentication on the ports, you first need to join the ports to either the registration or the mac detection vlan (as a security measure).

Next, define the RADIUS server host:

radius-server host 192.168.1.5 key useStrongerSecret

Next, we create a server-group that points to the PacketFence server,

aaa server-group radius "packetfence" host 192.168.1.5

Configure the AAA authentication for MAC authentication to use the right server-group:

aaa authentication mac-based chap-radius server-group "packetfence"

Optionally, you can configure the SSH and telnet authentication to point to PacketFence (make sure you also follow instructions in the Administration Guide to activate the CLI access):

aaa authentication login privilege-mode
aaa authentication ssh login radius server-group packetfence local
aaa authentication telnet login radius server-group packetfence local

Finally, enable MAC authentication on all necessary ports:

aaa port-access mac-based 1-24

Don’t forget to permit address moves and the reauth period. x represents the port index:

aaa port-access mac-based x addr-moves
aaa port-access mac-based x reauth-period 14400

(Thanks to Jean-Francois Laporte for this contribution)

5.19.3. 2610

802.1X

Define the RADIUS server host:

radius-server host 192.168.1.5 key "useStrongerSecret"
radius-server host 192.168.1.5 acct-port 1813 key "useStrongerSecret"

Define the SNMP configuration:

snmp-server host 192.168.1.5 community "public" informs trap-level not-info
no snmp-server enable traps link-change C1

Configure the server-group:

aaa server-group radius "packetfence" host 192.168.1.5

Configure authentication:

aaa authentication port-access eap-radius server-group "packetfence"
aaa authentication mac-based chap-radius server-group "packetfence"

Configure the port-security:

port-security C1 learn-mode port-access action send-alarm

Configuration of the port:

aaa port-access authenticator C1
aaa port-access authenticator C1 client-limit 1
aaa port-access authenticator active
aaa port-access mac-based C1
aaa port-access mac-based C1 addr-moves
aaa port-access mac-based C1 reauth-period 14400
aaa port-access C1 controlled-direction in

(Thanks to Denis Bonnenfant for this contribution)

5.19.4. 4100, 5300, 5400 Series

Port-Security

linkUp/linkDown traps are enabled by default and we have not found a way yet to disable them so do not forget to declare the trunk ports as uplinks in the switch config file.

On 4100’s, we need to secure bogus MAC addresses on ports in order for the switch to send a trap when a new MAC appears on a port. The ports are indexed differently on 4100’s: it’s based on the number of modules you have in your 4100, each module is indexed with a letter.

Global config settings

snmp-server community "public" Unrestricted
snmp-server host 192.168.1.5 "public" Not-INFO
no snmp-server enable traps link-change 1-26

You should configure interfaces like this:

port-security A1 learn-mode static action send-alarm mac-address 020000000001
...
port-security A24 learn-mode static action send-alarm mac-address 020000000024
port-security B1 learn-mode static action send-alarm mac-address 020000000025
...
port-security B24 learn-mode static action send-alarm mac-address 020000000048
port-security C1 learn-mode static action send-alarm mac-address 020000000049
...
MAC Authentication (with VoIP)

In order to have MAC Authentication working with VoIP, you need to ensure that the Voice VLAN is tagged on all the port first. You also need to activate lldp notification on all ports that will handle VoIP. Finally, make sure to change the value of the $VOICEVLANAME variable in the Procurve 5400 module’s source code.

RADIUS configuration radius-server host 192.168.1.5 key strongKey

MAC Authentication

aaa port-access mac-based C5-C7
aaa port-access mac-based C5 addr-limit 2
aaa port-access mac-based C6 addr-limit 2
aaa port-access mac-based C7 addr-limit 2
aaa port-access C5 controlled-direction in
aaa port-access C6 controlled-direction in
aaa port-access C7 controlled-direction in
802.1X (with VoIP)

Same as MAC Authentication, you need to ensure that the Voice VLAN is tagged on all the port first if using 802.1X. You also need to activate lldp notification on all ports that will handle VoIP. Finally, make sure to change the value of the $VOICEVLANAME variable in the Procurve 5400 module’s source code.

Downloadable ACLs

HP and Aruba switches running the ArubaOS-Switch operating system (previously called ProVision) support dynamic RADIUS-assigned ACLs. It requires RADIUS authentication using the 802.1X, Web authentication or MAC authentication available on the switch. You can define ACLs in PacketFence so that they can be automatically applied on the ports of the switches based on the role assigned. We have tested it successfully on the Aruba 2930M and 3810 series on version 16.05.0004.

To use this feature, first configure RADIUS and the authentication method on your switch. Next, in the PacketFence web admin interface, go to Configuration → Policies and Access Control → Switches. Click on the switch you want, then on the 'Roles' tab, and check 'Role by access list'. Now you are able to add ACLs for each role.

Configure RADIUS operation on the switch:

radius-server host <ipv4-address> key <key-string>

Configure RADIUS network accounting on the switch (optional).

aaa accounting network <start-stop|stop-only> radius

You can also view ACL counter hits using either of the following commands:

show access-list radius <port-list>
show port-access <authenticator|mac-based|web-based> <port-list> clients detailed

Configure an authentication method. Options include 802.1X, web-based authentication, and MAC authentication. You can configure 802.1X, web-based authentication, and/or MAC authentication to operate simultaneously on the same ports.

  • 802.1X Option:
    aaa port-access authenticator <port-list>
    aaa authentication port-access chap-radius
    aaa port-access authenticator active
  • MAC Authentication Option:
    aaa port-access mac-based <port-list>
  • Web Authentication Option:
    aaa port-access web-based <port-list>

This command configures web-based authentication on the switch and activates this feature on the specified ports.

For example, if you want the users that are in the registration VLAN to only use HTTP, HTTPS, DNS and DHCP you can configure this ACL in the registration role.

Registration ACL

Now, your normal users are placed in the 'default' role and your guests in the 'guest' role.

The 'default' role uses the network 192.168.5.0/24 and 'guest' uses the network 192.168.10.0/24.

You can prevent communications between both networks using these access lists

Cross network deny ACL

You could also only prevent your guest users from using shared directories

Deny shares ACL

You could also restrict your users to use only your DNS server where 192.168.5.2 is your DNS server

Force DNS ACL

5.23.4. Configuration for MAC authentication floating devices

To support floating devices on a Juniper switch you need to configure the 'flap-on-disconnect' option on each interface individually and remove it from the access-ports group.

# load replace terminal
[Type ^D at a new line to end input]
protocols {
dot1x {
authenticator {
authentication-profile-name packetfence;
interface {
ge-0/0/1.0 {
mac-radius{

}
}
ge-0/0/2.0 {

}
}
.....
access-ports {
supplicant multiple;
mac-radius {
restrict;
}
}
}
}
}
}
Ctrl-D
# commit comment "configured for floating devices"
flap-on-disconnect option takes effect only when the restrict option is also set.

5.24. LG-Ericsson

PacketFence supports iPECS series switches without VoIP using two different trap types:

  • linkUp / linkDown
  • Port Security (with static MACs)

On some recent models, we can also use more secure and robust features, like:

  • MAC Authentication
  • 802.1X

5.24.1. ES-4500G Series

LinkUp / LinkDown

Firmware 1.2.3.2 is required for linkUp / linkDown

Prior to config, make sure to create all necessaries VLANs and config the appropriate uplink port.

Global config settings

snmp-server community public ro
snmp-server community private rw
!
snmp-server enable traps authentication
snmp-server host 192.168.1.5 public version 2c udp-port 162
snmp-server notify-filter traphost.192.168.1.5.public remote 192.168.1.5

Firmware is kinda buggy so you’ll need to enable linkUp / linkDown using the Web Interface under Administration → SNMP.

Some reports shows that the switch doesn’t always send linkDown traps.

On each interface (except uplink)

switchport allowed vlan add 4 untagged
switchport native vlan 4
switchport allowed vlan remove 1
switchport mode access
Port-Security

Firmware 1.2.3.2 is required for port-security.

Prior to config, make sure to create all necessaries VLANs and config the appropriate uplink port.

Global config settings

snmp-server community public ro
snmp-server community private rw
!
snmp-server enable traps authentication
snmp-server host 192.168.1.5 public version 2c udp-port 162
snmp-server notify-filter traphost.192.168.1.5.public remote 192.168.1.5

On each interface (except uplink)

port security max-mac-count 1
port security
port security action trap
switchport allowed vlan add 2 untagged
switchport native vlan 2
switchport allowed vlan remove 1
switchport mode access

The above port security command may not work using the CLI. In this case, use the Web Interface under the Security → Port Security menu and enable each ports using the checkboxes.

It is also recommended, when using port-security, to disable link-change (UP / DOWN) traps.

Don’t forget to update the startup config!

5.25. Linksys

PacketFence supports Linksys switches without VoIP using one trap type:

  • linkUp/linkDown

Don’t forget to update the startup config!

5.25.1. SRW224G4

Global config settings

no snmp-server trap authentication
snmp-server community CS_2000_le rw view Default
snmp-server community CS_2000_ls ro view Default
snmp-server host 192.168.1.5 public 2

On each interface

switchport access vlan 4

5.26. Netgear

The "web-managed smart switch" models GS108Tv2/GS110/GS110TP are supported with Link up/down traps only.

Higher-end "fully managed" switches including FSM726v1 are supported in Port Security mode.

5.26.1. FSM726 / FSM726S version 1

PacketFence supports FSM726 / FSM726S version 1 switches without VoIP in Port Security mode (with static MACs) – called Trusted MAC table on Netgear’s hardware.

Using the HTTP GUI, follow the steps below to configure such feature. Of course, you must create all your VLANs on the switch as well.

SNMP Settings

In Advanced → SNMP → Community Table, create a read-write community string and a trap community string. You can use the same community for all the 3 functions (Get, Set, Trap).

Next, under Advanced → SNMP → Host Table, enable the Host Authorization feature and add the PacketFence server into the allowed host list.

Finally, under Advanced → SNMP → Trap Setting, enable the authentication trap.

Trusted MAC Security

Under Advanced → Advanced Security → Trusted MAC Address, create a fake MAC address per port (ie. 02:00:00:00:00:xx where xx is the port number). This will have the effect of sending a security trap to PacketFence when a new device plugs on the port.

Don’t forget to save the configuration!

5.26.2. GS108Tv2 / GS110T / GS110TP

PacketFence supports certain lower-end Netgear switches in Link Up/Link Down traps. These "web-managed" switches have no command-line interface and only a subset of the port security and 802.1X functionality needed to interoperate with PacketFence in these more advanced modes. There is no way to send a trap upon port security violation, and there is only pure 802.1X, no MAC Address Bypass.

Switch Configuration

It can be difficult to find the advanced features in the web GUI. We recommend using the GUI "Maintenance" tab to Upload the configuration to a file, and then edit it there.

Hints on file upload/download:

From the File Type menu, choose Text Configuration.

If you’re uploading to the TFTP root directory, leave Path blank.

At the top of the config file, you need:

vlan database
vlan 1,2,3,4,5
vlan name 1 "Normal"
vlan name 2 "Registration"
vlan name 3 "Isolation"
vlan name 4 "MAC Detection"
vlan name 5 "Guest"
exit

In the same section as "users passwd", you need to specify your PacketFence server’s management address:

snmptrap useStrongerSecret ipaddr 192.168.1.5

In the same section as the "voip oui" lines, you need to allow your SNMP server:

snmp-server community "public"
snmp-server community rw useStrongerSecret
snmp-server community ipaddr 192.168.1.5 public
snmp-server community ipmask 255.255.255.0 public
snmp-server community ipaddr 192.168.1.5 useStrongerSecret
snmp-server community ipmask 255.255.255.0 useStrongerSecret
no voip vlan

You should use port 1 as the uplink. If you connect port 1 of a GS108Tv2 switch into a Power over Ethernet switch, then the GS108Tv2 does not need AC power. If you bought GS110T(P) switches, presumably it’s for the SFP uplink option. You’ll want to configure both port 1 and the SFP ports 9-10 as trunks:

interface 0/1
no snmp trap link-status
ip dhcp filtering trust
vlan pvid 1
vlan ingressfilter
vlan participation include 1,2,3,4,5
vlan tagging 2,3,4,5
no auto-voip
exit

Each user-facing, PacketFence-managed port should be configured like:

interface 0/2
vlan pvid 4
vlan ingressfilter
vlan participation include 4
no auto-voip
exit

5.26.3. M Series

PacketFence supports the Netgear M series in wired MAC authentication without VoIP.

5.27. Nortel

PacketFence supports Nortel switches with VoIP using one trap type:

  • Mac Security

Don’t forget to update the startup config!

if you are using a 5500 series with a firmware version of 6 or above, you must use a different module called Nortel::BayStack5500_6x in your /usr/local/pf/conf/switches.conf. Indeed, Nortel introduced an incompatible change of behavior in this firmware.

5.27.1. BayStack 470, ERS2500 Series, ERS4500 Series, 4550, 5500 Series and ES325

Global config settings

5.28. Pica8

PacketFence supports Pica8 switches without VoIP using CoA to:

  • bounce-host-port
  • reauthenticate-host

Notes

  • SNMP is not supported yet
  • Port Security is not supported

For interfaces with MAC Authentication, perform the following:

set interface gigabit-ethernet ge-1/1/25 family ethernet-switching port-mode trunk
set protocols dot1x interface ge-1/1/25 auth-mode mac-radius
set protocols dot1x interface ge-1/1/25 dynamic-vlan-enable true

commit
  • 10.10.51.169 is the switch IP
  • For interfaces where auth-mode is unknown, use the following command set protocols dot1x interface ge-1/1/12 auth-mode dot1x-mac-radius This allows the switch to first try 802.1X and if there is no response from the client then fallback to MAC Authentication.
  • Create VLAN(s) on the switch as per your requirements
  • Please note that traceoptions are only for debugging

5.29. SMC

6. Wireless Controllers and Access Point Configuration

6.1. Assumptions

Throughout this configuration example we use the following assumptions for our network infrastructure:

  • PacketFence is fully configured with FreeRADIUS running
  • PacketFence IP address: 192.168.1.5
  • Normal VLAN: 1
  • Registration VLAN: 2
  • Isolation VLAN: 3
  • MAC Detection VLAN: 4
  • Guest VLAN: 5
  • VoIP, Voice VLAN: 100
  • use SNMP v2c
  • SNMP community name: public
  • RADIUS Secret: useStrongerSecret [1]
  • Open SSID: PacketFence-Public
  • WPA-Enterprise SSID: PacketFence-Secure

6.2. Unsupported Equipment

Wireless network access configuration is a lot more consistent between vendors. This is due to the fact that the situation is a lot more standardized than the wired side: VLAN assignment is done centrally with RADIUS and that the client protocol is consistent (MAC-Authentication or 802.1X).

This consistency has the benefit that a lot of the wireless network devices tend to work out-of-the-box with PacketFence. The only missing piece being, in most cases, remote deauthentication of the client which is used for VLAN assignment (deauth user so it’ll reconnect and get new VLAN).

So, even if your wireless equipment is not explicitly supported by PacketFence, it’s recommended that you give it a try. The next section covers the objectives that you want to accomplish for trying out your equipment even if we don’t have configuration for it.

Here are the high-level requirements for proper wireless integration with PacketFence

  • The appropriate VLANs must exist
  • Allow controller to honor VLAN assignments from AAA (sometimes called AAA override)
  • Put your open SSID (if any) in MAC-Authentication mode and authenticate against the FreeRADIUS hosted on PacketFence
  • Put your secure SSID (if any) in 802.1X mode and authenticate against FreeRADIUS hosted on PacketFence.
  • On registration / isolation VLANs the DHCP traffic must reach the PacketFence server
  • On your production VLANs a copy of the DHCP traffic must reach PacketFence where a pfdhcplistener listens (configurable in pf.conf under interfaces)

At this point, user registration with the captive-portal is possible and registered users should have access to the appropriate VLANs. However, VLAN changes (like after a registration) won’t automatically happen, you will need to disconnect / reconnect. An explanation is provided in introduction section above about this behavior.

You can try modules similar to your equipment if any (read appropriate instructions) or you can try to see if RFC3576 is supported. RFC3576 covers RADIUS Packet of Disconnect (PoD) also known as Disconnect Messages (DM) or Change of Authorization (CoA). You can try the Aruba module if you want to verify if RFC3576 is supported by your hardware.

If none of the above worked then you can fallback to inline enforcement or let us know what equipment you are using on the packetfence-devel mailing list.

6.3. Aerohive Networks

Aerohive products are a bit different compared to the other vendors. They support either a local HiveManager (similar to a wireless controller) or a cloud-based HiveManager. However, the configuration is the same for the local and the cloud-based controller. Note that all the configurations are made on the HiveManager and then pushed to the APs.

6.3.1. MAC Authentication and 802.1X Configuration

Assumptions
  • the network architecture is in order to give acces to the Aerohive Access Point, and has access to Internet
  • the VLANs are defined for registration, isolation and management networks
  • from this documentation, we will assume that the VLANs tags are define like following:
    • PacketFence Management VLAN: 1 IP address: 192.168.1.5
    • registration VLAN ID 2, subnet 192.168.2.0/24
    • isolation VLAN ID 3, subnet 192.168.3.0/24
    • production VLAN ID 10, subnet 172.16.1.0/24
  • the VLANs are spanned in the switches and switching L2 equipments, from the Production Network to the PacketFence server(s)
  • the VLANs are allowed in the trunks
  • Aerohive Access Point is loaded with HiveOS with version 6 or later
  • HiveManager with version 6 or later
  • Wireless AP: 172.16.1.1
  • RADIUS Secret: useStrongerSecret
Configure the Aerohive APs and SSID

Logon to your HiveManager interface:

  • for this example, we assume that we are on the Cloud MyHive.aerohive.com solution
  • from HiveManager, click on your HiveManagerOnline Instances VHM-XXXXXX
  • from Network Configuration / 1-Choose Network Policy, click on New
  • give a name to your Policy, and click Create
  • from 2-Configure Interfaces and User Access, SSID, click on Choose and click on New
  • give a SSID Profile Name, SSID Name

For an open (no encryption) SSID using MAC-based authentication:

  • click on New
    • SSID Access Security: Open
    • check the box Enable MAC authentication
  • click on Save
AerohiveOpenSSIDconfig

For a secure SSID using 802.1X:

  • click on New
    • SSID Access Security: WPA/WPA2 802.1X (Enterprise)
    • Key Management; WPA2-(WPA2 enterprise)-802.1X
    • Encryption method: CCMP (AES)
AerohiveSecuredSSIDconfig
  • click on Save
  • from SSID, be sure to have selected both SSIDs previously created, and click OK

Add the RADIUS parameters created before:

  • under Authentication click on <RADIUS Setting>, and click on New
  • from RADIUS Name, give the name of the PaketFence server, for example
AAA Radius config
  • from Add a New RADIUS Server, in IP Adresse/Domain Name, put the PacketFence Server IP
  • hive the Shared Secret (useStrongerSecret) and Confirm it
  • and Click on Apply
AAA Radius config
  • deploy the Optionnal Setting(not supported by RADIUS Proxy) section and check the Permit Dynamic Change of Authorization Message (RFC 3576)
  • click on Save
  • next to your SSID Name Click on the <RADIUS Setting>, Click OK

We will create the default VLAN to be assign by the AP, when a new endpoint get in the SSID:

  • Under User Profile, Click on Add/Remove,and Click on New, in the Default section
    • You will need to create one User Profile for each VLANs used, for us, we will create 3 Users Profiles, Registration, Isolation and Production
  • from name, give the name of a rule to manage the VLANs with PacketFence (Registration ; Isolation ; Production)
  • from Attribute Name, give the VLAN ID of the VLAN
  • from Default VLan, Click on the (+) (New)
  • as a VLAN ID, give the VLAN ID earlier Registration(2) , Isolation(3) or Production(10)
  • click on Save and click on Save again on the Configure interfaces and User Access
User Profile creation

Create and add the other VLANs:

  • Follow the same procedure to create the others VLANs

Once done with the VLANs configuration:

  • From the Choose User Profiles, select the Default tab and click on you Registration VLAN tag
  • From the Authentication tab, select the Isolation and the Production VLANs tag
  • Click on Save

For our example, here is what it looks like, with two SSIDs

User Profile creation

Then, click on Continue, on top right of the page.

Push your configuration to your AP:

  • from Configure and Update Devices, check your AP in Device to Update
  • click on Update
  • select Update Devices
  • from HiveOS Number of devices running earlier versions of HiveOS, select Upgrade these devices to the latest version of HiveOS
  • click on Update
  • wait until the date and time apprears under Update Status
Aerohive have a session replication feature to ease the EAP session roaming between two access points. However, this may cause problems when you bounce the wireless card of a client, it will not do a new RADIUS request. Two settings can be tweaked to reduce the caching impact, it is the roaming cache update interval and roaming cache ageout. They are located in Configuration → SSIDs → [SSID Name] → Optional Settings → Advanced. The other way to support Roaming is to enable SNMP trap in the Aerohive configuration to PacketFence server. PacketFence will recognize the ahConnectionChangeEvent and will change the location of the node in his base.
Configure PacketFence

We will now need to create a new switch in PacketFence to be able to manage the endpoints behind the Aerohive APs.

Logon to your PacketFence interface:

  • from Configuration / Policies and Access Control / Switches /
  • on the line where there is the default, on the right, Click on CLONE
New switch configuration

In Definition:

  • IP Address/MAC Address/Range (CIDR), give the network address of your Production network; For us, it will be 172.16.1.1
  • Description, give a description so you can quickly see what it is about
  • from the Type list, select Aerohive AP
  • from Mode select Production
  • Switch Group by default set to None
  • Deauthentication Method set to RADIUS
  • click SAVE
New switch configuration

From Role:

  • set all VLAN ID for each roles
New switch configuration

From RADIUS:

  • modify the secret passphrase previously sets in the Aerohive HiveManager
  • click on SAVE

This ends the PacketFence configuration.

6.3.2. Web Auth (External Captive Portal) Configuration

In this section we will describe the WebAuth configuration using PacketFence as an external captive poral.

Assumptions

In this part, it is recommended that the default VLAN must be the native VLAN. This way, the AP and the others network equipments will be able to manage VLANs.

You already have a Network Policy and at least one Access Point configured.

Captive Portal SSID configuration

6.3.3. MAC Authentication/802.1X and Web Auth Configuration

In this case we want to be able to enable a MAC Authentication/802.1X and Web Auth SSID on the same wireless equipment. By default it’s not possible to provide a MAC Authentication/802.1X SSID and a Web Auth SSID with the same switch configuration, but by using the Switch Filters it will be possible to do it.

We will assume that we have an up and running SSID (YourSecuredSSID) already configured with Mac Authentication/802.1X:

  • from this documentation, we will assume that the VLANs tags are defined like following :
    • PacketFence Management VLAN: 1 IP address: 192.168.1.5
    • registration VLAN ID 2,subnet 192.168.2.0/24
    • isolation VLAN ID 3, subnet 192.168.3.0/24
    • production VLAN ID 10, subnet 172.16.1.0/24

Our SSID will be named YourOpenSSID, assuming that we want to provide a public Internet hotspot for example.

Add a New SSID

You should create a new SSID, has explained before, secured or open, as you need.

Configure Filters in PacketFence

Logon to your PacketFence server:

  • Go to Configuration → Advanced Acccess Configuration → Filter Engines
  • From the tab Switch filters,
  • Go to the bottom of the configuration file and set the folllowing section.
[enable_external_portal_on_guest_ssid]
status=enabled
description=enable_external_portal_on_guest_ssid
scopes=radius_authorize
param.0=ExternalPortalEnforcement=Y
top_op=and
param.1=VlanMap=N
condition=ssid == "YourOpenSSID"

Click on SAVE.

The default configuration in the Switch filters for ExternalPortalEnforcement is set to N

6.3.4. Advanced Topics

Roles (User Profiles)

PacketFence supports user profiles on the Aerohive equipment. To build a User Profile, go to Configuration → User Profiles, and create what you need. When you define the switch definition in PacketFence, the role will match the User Profile attribute number. For example:

roles=CategoryStudent=1;CategoryStaff=2

And in the Aerohive configuration, you have:

StudentProfile attribute number 1
StaffProfile attribute number 2

Last step is to allow the User Profile to be returned for a particular SSID. Go to Configuration → SSIDs → Your_SSID → User Profiles for Traffic Management, and select the User Profiles you will return for the devices.

In version 6 or later of the HiveOS, we do return VLAN ID matching the number that the User Profile has. Create your User Profile in the HiveManager as usual, assign the matching VLAN, and in PacketFence configuration add the wanted VLAN ID in the section Roles by VLAN.

Roles (User Profiles)

Since PacketFence 3.3.0, we now support user profiles on the AeroHIVE hardware. To build a User Profile, go to Configuration → User Profiles, and create what you need. When you define the switch definition in PacketFence, the role will match the User Profile attribute number. Example

roles=CategoryStudent=1;CategoryStaff=2

And in the AeroHIVE configuration, you have :

StudentProfile attribute number 1
StaffProfile attribute number 2

Last step is to allow the User Profile to be returned for a particular SSID. Go to Configuration → SSIDs → Your_SSID → User Profiles for Traffic Management*, and select the User Profiles you will return for the devices.

In version 6 or later of the HiveOS, we do return VLAN ID matching the number that the User Profile has. Create your User Profile in the HiveManager as usual, assign the matching VLAN, and in PacketFence configuration add the wanted VLAN ID in the section Roles by VLAN.

6.4. Anyfi Networks

This section will discuss about the configuration of your Anyfi Gateway and Controller in order to use it with our configured PacketFence environment.

6.4.1. Deploy Anyfi Controller and Gateway

First thing, you will need to deploy the Anyfi Gateway and Controller on your network and configure basic connectivity between both of them.

When installing the Anyfi Gateway, have one interface in trunk mode for the packet bridge. In this example it will be eth2 which is the last card on the machine.

6.4.2. Anyfi Gateway Basic Configuration

Connect to the gateway using SSH and enter configuration mode. Now you need to add the configuration for `br0 which will link the access point traffic to your network.

interfaces {
bridge br0 {
aging 300
hello-time 2
max-age 20
priority 0
stp false
}
}

In this example eth1 will be the management interface of the Anyfi Gateway and eth2 will be the interface that will contain the outbound WiFi traffic.

interfaces {
ethernet eth1 {
address <your management ip address>/<mask>
duplex auto
smp_affinity auto
speed auto
}
ethernet eth2 {
bridge-group {
bridge br0
}
duplex auto
smp_affinity auto
speed auto
}
}

6.4.3. Open SSID Configuration

Still in configuration mode, configure the RADIUS server and SSID security.

service {
anyfi {
gateway ma-gw {
accounting {
radius-server <Management IP of PacketFence> {
port 1813
secret useStrongerSecret
}
}
authorization {
radius-server <Management IP of PacketFence> {
port 1812
secret useStrongerSecret
}
}
bridge br0
controller <IP or FQDN of the Anyfi Controller>
isolation
nas {
identifier anyfi
port 3799
}
ssid DemoOpen
}
}

6.4.4. Secure SSID Configuration

Still in configuration mode, configure the Anyfi Gateway to broadcast a WPA2 enterprise SSID.

service {
anyfi{
gateway secure-gw {
authentication {
eap {
radius-server <Management IP of PacketFence> {
port 1812
secret useStrongerSecret
}
}
}
bridge br0
controller <IP or FQDN of the Anyfi Controller>
isolation
ssid DemoSecure
wpa2 {
}
}
}
}

6.4.5. Deploy Access Point

You will now need to install CarrierWRT on a compatible access point and configure the Anyfi Controller in it. Depending on the access point you’re using, the method to install CarrierWRT will vary. For specifics about the CarrierWRT installation, refer to Anyfi’s documentation. Once this step is done, the SSID should be broadcasted.

6.6. Aruba

6.6.1. All Aruba OS

In this section, we cover the basic configuration of the Aruba wireless controller for PacketFence via the web GUI. It was done on an Aruba Controller 200 software version ArubaOS 5.0.3.3, tested on a Controller 600 with ArubaOS 6.0 but it should apply to all Aruba models.

If you are already using your Aruba controllers and don’t want to impact your users you should create new AAA profiles and apply them to new SSIDs instead of modifying the default ones.
Starting with PacketFence 3.3, Aruba supports role-based access control. Read the Administration Guide under "Role-based enforcement support" for more information about how to configure it on the PacketFence side.
AAA Settings

In the Web interface, go to Configuration → Authentication → RADIUS Server and add a RADIUS server named "packetfence" then edit it:

  • Set Host to PacketFence’s IP (192.168.1.5)
  • Set the Key to your RADIUS shared secret (useStrongerSecret)
  • Click Apply

Under Configuration → Authentication → Server Group add a new Server Group named "packetfence" then edit it to add your RADIUS Server "packetfence" to the group. Click Apply.

Under Configuration → Authentication → RFC3576 add a new server with PacketFence’s IP (192.168.1.5) and your RADIUS shared secret (useStrongerSecret). Click Apply. Under Configuration → Authentication → L2 Authentication edit the MAC Authentication Profile called "default" then edit it to change the Delimiter to dash. Click Apply.

Under Configuration → Authentication → L2 Authentication edit the 802.1X Authentication Profile called "default" then edit it to uncheck the Opportunistic Key Caching under Advanced. Click Apply.

Under Configuration → Authentication → AAA Profiles click on the "default-mac-auth" profile then click on MAC Authentication Server Group and choose the "packetfence" server group. Click Apply. Move to the RFC3576 server sub item and choose PacketFence’s IP (192.168.1.5) click add then apply.

Under Configuration → Authentication → AAA Profiles click on the "default-dot1x" profile then click on 802.1X Authentication Server Group and choose the "packetfence" server group. Click Apply. Move to the RFC3576 server sub item and choose PacketFence’s IP (192.168.1.5) click add then apply.

Public SSID

In the Web interface, go to Configuration → AP Configuration then edit the "default" AP Group. Go in Wireless LAN → Virtual AP create a new profile with the following:

  • AAA Profile: default-mac-auth
  • SSID Profile: Select NEW then add an SSID (PacketFence-Public) and Network authentication set to None
Secure SSID

In the Web interface, go to Configuration → AP Configuration then edit the "default" AP Group. Go in Wireless LAN → Virtual AP create a new profile with the following:

  • AAA Profile: default-dot1x
  • SSID Profile: Select NEW then add an SSID (PacketFence-Secure) and Network authentication set to WPA2
Roles

Since PacketFence 3.3.0, we now support roles for the Aruba hardware. To add roles, go in Configuration → Access Control → User Roles → Add. You don’t need to force a VLAN usage in the Role since we send also the VLAN ID along with the Aruba User Role in the RADIUS request. Refer to the Aruba User Guide for more information about the Role creation.

WIPS

In order to use the WIPS feature in PacketFence, please follow those simple steps to send the traps to PacketFence.

First, configure PacketFence to be a trap receiver. Under Configuration → SNMP → Trap Receivers, add an entry for the PF management IP. By default, all traps will be enabled. If you want to disable some, you will need to connect via CLI, and run the snmp-server trap disable <trapname> command.

WebAuth

First of all you will need to configure a guest VLAN.

Guest VLAN

Next, you will need to configure a RADIUS server.

RADIUS server
aaa authentication-server radius "packetfence"
host 192.168.1.5
key useStrongerSecret

Add your RADIUS server to a AAA group, under Security → Authentication → Servers → Server Group:

aaa server-group "packetfence"
auth-server "packetfence" position 1

Then define the RFC 3576 server, which will allow you to do CoA.

RADIUS CoA server
aaa rfc-3576-server "192.168.1.5"
key useStrongerSecret

Next, you will need to create the policy that will redirect users to the PacketFence captive portal when they are not authenticated. Go to Security → Authentication → L3 Authentication → Captive Portal Authentication Profile.

Layer 3 profile
Layer 3 profile 2
aaa authentication captive-portal "packetfence-externalportal"
default-role auth-guest
redirect-pause 3
no logout-popup-window
login-page https://192.168.1.5/Aruba
switchip-in-redirection-url

Now create the policy for the guest access, for example Internet only.

Add the authentication for the Captive Portal Profile via Security → Authentication → L3 Authentication → Captive Portal Authentication Profile → Server Group:

aaa authentication captive-portal "packetfence-externalportal"
server-group "packetfence"

Adjust the configuration of the AAA profile through Security → Authentication → Profiles → AAA Profiles:

AAA profile 1
AAA profile 2
AAA profile 3
AAA profile 4
AAA profile 5
AAA profile 6
aaa profile "packetfence-externalportal"
initial-role packetfence-portal
radius-interim-accounting
radius-accounting "packetfence"
rfc-3576-server "192.168.1.5"

Define a policy to permit the traffic.

First add a destination, Advanced Services → Stateful Firewall → Destinations:

netdestination packetfence-portal
host 192.168.1.5

Create an ACL for the redirection, Security → Firewall Policies:

Policy 1
Policy 2
Policy 3
Policy 4
Policy 5

Source NAT on VLAN

ip access-list session "packetfence-externalportal"
alias "user" alias "packetfence-portal" "svc-http" permit queue low
alias "user" alias "packetfence-portal" "svc-https" permit queue low

Enable the "firewall allow-tri-session" :

firewall allow-tri-session

Source NAT per Application

ip access-list session "packetfence-externalportal"
alias "user" alias "packetfence-portal" "svc-http" src-nat queue low
alias "user" alias "packetfence-portal" "svc-https" src-nat queue low

Now add the newly created policy to the Captive Portal Profile, Security → User Roles:

User Role
Interface de redirection
user-role "packetfence-portal"
access-list session "packetfence-externalportal" position 1
access-list session "captiveportal" position 2
access-list session "guest-logon-access" position 3
access-list session "block-internal-access" position 4
access-list session "v6-logon-control" position 5
access-list session "captiveportal6" position 6
captive-portal "packetfence-externalportal"

Finaly create the SSID and associate the profile to it, Virtual AP profile:

wlan virtual-ap "packetfence-externalportal"
ssid-profile "packetfence-externalportal"
aaa-profile "packetfence"

General AP settings and master-slave controller case.

The next step will be to configure the Aruba WiFi controller for WebAuth in PacketFence, add the switch with the model choice Aruba Network,

Add Aruba wireless controller
Aruba wireless controller roles configuration

Check the box External Portal Enforcement, in the Roles section, choose Role by Switch Role, as the registration role, enter your default role: packetfence-portal and choose the policy matching roles, for instance guest: internet-only.

CLI authentication

In order to enable CLI login on the Aruba controller via the PacketFence server, you need to point management authentication to the RADIUS server you created while configuring the SSIDs in the previous sections above.

aaa authentication mgmt default-role read-only enable server-group PacketFence

6.6.2. Aruba Controller 200

In this section, we cover the basic configuration of the Aruba Controller 200 for PacketFence using the command line interface. We suggest you to use the instructions above for the Web GUI instead.

VLAN definition

Here, we create our PacketFence VLANs, and our AccessPoint VLAN (VID 66). It is recommended to isolate the management of the thin APs in a separate VLAN.

6.11.4. Wireless LAN Controller (WLC) or Wireless Services Module (WiSM)

In this section, we cover the basic configuration of the WiSM for PacketFence using the web interface.

  • First, globally define the FreeRADIUS server running on PacketFence (PacketFence’s IP) and make sure Support for RFC 3576 (also called Support for CoA) is enabled. When the option is missing from your WLC, it is enabled by default.
Freeradius server
  • Then we create two SSIDs:
    • PacketFence-Public: non-secure with MAC authentication only
    • PacketFence-Secure: secure with WPA2 Enterprise PEAP/MSCHAPv2
SSID creation
  • In the secure SSID, make sure 802.1X is enabled and select the appropriate encryption for your needs (recommended: WPA + WPA2)
SSID L2 secure
  • No layer 3 security
SSID L3 secure
  • We set the IP of the FreeRADIUS server
Radius secure
  • VERY IMPORTANT: Allow AAA override (this allows VLAN assignment from RADIUS)
Radius advanced secure
  • Edit the non-secure SSID: Enable MAC authentication at level 2
SSID L2 non secure
  • Nothing at level 3
SSID L3 non secure
  • We set the IP of the FreeRADIUS server
Radius secure
  • VERY IMPORTANT: Allow AAA override (this allows VLAN assignment from RADIUS)
Radius advanced non secure
  • Finally, in Controller → Interfaces tab, create an interface per VLAN that could be assigned
SSID Interface
When creating interfaces, it’s important to configure DHCP servers. Otherwise, WLC will block DHCP requests.

You are good to go!

Wireless LAN Controller (WLC) Web Auth

In this section, we cover the basic configuration of the WLC Web Auth for PacketFence using the web interface. The idea is to forward the device to the captive portal with an ACL if the device is in an unreg state and allow the device to reach Internet (or the normal network) by changing the ACL once registered. In the unreg state, the WLC will intercept the HTTP traffic and forward the device to the captive portal.

In this sample configuration, the captive portal uses the IP address 172.16.0.250, the administration interface uses the IP address 172.16.0.249 and the WLC uses the IP address 172.16.0.248. The DHCP and DNS servers are not managed by PacketFence (WLC DHCP Server, Production DHCP Server)

  • First, globally define the FreeRADIUS server running on PacketFence (PacketFence’s Administration Interface) and make sure Support for RFC 3576 is enabled (if not present it is enabled by default)
  • Then we create a SSID:
    • OPEN SSID: non-secure with MAC authentication only
SSID step 1
SSID step 2
SSID step 3
SSID step 4
SSID step 5
SSID step 6
On more recent controllers, the value 'Radius NAC' in the 'NAC State' setting will be called 'ISE NAC'.
SSID step 7
  • Then you have to create two ACLs - one to deny all traffic except the required one to hit the portal (Pre-Auth-For-WebRedirect ) and the other one to allow anything (Authorize_any) .
ACL
  • Then the last step is to configure the WLC in PacketFence. Role by Web Auth URL

Wireless LAN Controller (WLC) IPSK

In this section, we cover the basic configuration of the WLC IPSK feature. Starting from WLC 8.5 release, Cisco introduces the IPSK feature. Identity PSKs are unique pre-shared keys created for individuals or groups of users on the same SSID.

In this section we will cover the WLC configuration and the PacketFence configuration.

WLC Configuration:

  • First, globally define the RADIUS server running on PacketFence (PacketFence’s IP) and make sure Support for RFC 3576 (also called Support for CoA) is enabled. When the option is missing from your WLC, it is enabled by default.
  • Next, configure a new SSID like in the following screenshots
SSID step 1
SSID step 2
SSID step 3
SSID step 4

PacketFence Configuration:

  • First because there is no way to detect in the RADIUS request that the request is for an SSID configured for IPSK, you need to configure PacketFence to trigger IPSK on a connection profile. To do that, create a new connection profile, set a Filter based on the SSID (Example SSID PSK_SSID), enable IPSK and set a default PSK key. So each time a device will connect on this specific SSID PacketFence will know that it has to answer with specific VSA attributes.
  • Second step is to associate the device to a user, you have two ways to do it, the first one is to manually edit an user and in Miscellaneous tab fill the PSK entry (8 characters minimum) then edit a node and change the owner with the one you just edit before. The second way to associate the device is to use a provisioner. There are also 2 ways to do it, use the "IPSK" provisioner (it will show you a page on the portal with the PSK key to use and the SSID to connect to, or use the "Windows/Apple Devices/Android" provisioner and configure it to do IPSK.

6.11.6. Troubleshooting ignored RADIUS replies

In the event the WLC ignores the RADIUS replies from PacketFence (you receive multiple requests but access is never granted), validate the following elements :

  • RADIUS secret is properly configured in PacketFence and the WLC controller.
  • The SSL certificate used by PacketFence is not expired.

6.11.7. Device Sensor

When using a Cisco WLC, you can enable device sensor by making sure the configuration looks like the following screenshot:

Device Sensor
Please refer to the wired configuration of Cisco equipment to learn more about device sensor.

6.12. CoovaChilli

This section has been created in order to help setting up a consumer grade access point running CoovaChilli integration with PacketFence to use UAM capabilities along with PacketFence feature set.

6.12.1. Assumptions

  • You have a CoovaChilli capable access point running LEDE/OpenWRT, on which CoovaChilli is installed (CoovaChilli installation is not covered in this guide);
  • A working PacketFence server, a CoovaChilli capable access point, and Internet is functional;
  • A PacketFence WebAuth enforcement setup will be deployed;

6.12.2. Access Point and CoovaChilli Configuration

We go ahead and start by configuring the access point and CoovaChilli running on it.

These instructions assume that CoovaChilli is installed on the access point. If it’s not, we suggest you search relevant information on the Internet to install CoovaChilli as there are too many network equipment vendors that support CoovaChilli to accurately document this step here.

These instructions also assume that you have an SSID configured on the access point. Assumption is also made that the network interface / bridge is configured and assigned for the given SSID.

You should also make sure to have a default route properly configured on the access point (so that it can access the Internet) and that DNS resolution is working.

Also note that changes on the OpenWRT access point are done using SSH shell access.

Please note that any interface name reference might be different from one equipment vendor to an other.

Configure chilli

chilli configuration might differ from one equipment vendor to an other one. Just make sure to follow these configuration guidelines and you should be all-set.

  • chilli configuration file can be found under
    /etc/config/chilli
  • Edit the following parameters to integrate with PacketFence
    option disabled 1 This should be commented out so that chilli is marked as enabled
    option dns1 Set this to a working DNS server (this will be used by hotspot clients)
    option dns2 Set this to a working DNS server (this will be used by hotspot clients)
    option ipup /etc/chilli/up.sh (Depending on the package, the script path might need to be adjusted)
    option ipdown /etc/chilli/down.sh (Depending on the package, the script path might need to be adjusted)
    option radiusserver1 PacketFence management IP
    option radiusserver2 PacketFence management IP
    option radiussecret The RADIUS secret that will be used between chilli and PacketFence
    option radiusnasid Access-point IP address
    option dhcpif The network interface / bridge assigned to the SSID (Hotspot clients network)
    option uamserver http://PACKETFENCE_MANAGEMENT_IP/CoovaChilli
    option ssid SSID name
    option nasip Access-point IP address
    option coaport 3799

A startup script might be required depending on the equipment vendor. Again, a quick documentation search on the Internet might be the best solution to find the best one

Once set up, you might want to activate chilli at boot (by using the startup script) and finally, reboot the AP.

6.12.3. PacketFence Configuration for CoovaChilli Integration

Having a working PacketFence installation and a configured LEDE / OpenWRT access point running CoovaChilli, the last step is PacketFence configuration for CoovaChilli integration.

To do so, login to the PacketFence web administration interface if it is not already done.

Switch configuration

Click on the 'Configuration' tab and select the 'Switches' menu option under the 'NETWORK' section on the left hand side.

On the bottom of the page, click the 'Add switch to group' button then select the 'default' to bring up the 'New Switch' configuration modal window.

'Definition' tab

  • IP: Access-point IP address
  • Type: CoovaChilli
  • Mode: Production
  • External Portal Enforcement: Checked

'RADIUS' tab

  • Secret Passphrase: The RADIUS secret configured in the previous step

Click 'Save'

Portal configuration

It is required to disable HTTPS redirection by clicking the 'Configuration' tab and then the 'Captive portal' menu option on the left hand side. Make sure 'Secure redirect' is unchecked.

6.14. Extreme Networks

6.14.1. Access points AP305C (managed by Extreme Cloud IQ Controller)

In such deployment, PacketFence communicates directly with the access points using RADIUS. The Extreme Cloud IQ controller is only used to configure access points in a central place.

Web authentication
Extreme Cloud IQ Controller

On the Extreme Cloud IQ Controller, there should already be two built-in IP Firewall policies:

  • Redirect-only policy: this policy must have "redirect" rules
  • Internet-access-only policy

On the Extreme Cloud IQ Controller, create two user profiles:

  • Registration
  • Guest
    • VLAN: 5
    • Firewall rules: Enabled
    • IP Firewall Name: Internet-access-only policy

Still, on the Extreme Cloud IQ Controller, create a wireless network with the following configuration:

  • SSID Authentication: Open
    • Enable Captive Web Portal: No
  • MAC Authentication tab
    • Enable MAC authentication: Yes
    • Authentication protocol: CHAP
    • Authenticate via RADIUS server
      • Create a RADIUS group with an External RADIUS Server
        • Permit Dynamic Change Of Authorization Messages (RFC 3576): Enabled
    • User access settings
      • Apply a different user profile to various clients and user groups: Enabled
        • Allow user profile assignment using RADIUS attributes in addition to the three tunnel RADIUS attributes: Enabled
          • Standard RADIUS Attribute: Filter-Id

Under User access settings, you need to create following rules:

Table 1. User Access Settings rules
User profile name VLAN/VLAN Group Assignment rules
Registration
5
If Filter-ID equals "Registration"
Guest
5
If Filter-ID equals "Guest"
PacketFence

Create a switch with following configuration:

  • Definition tab
    • Identifier: subnet of your Extreme AP
    • External portal enforcement: Yes
    • Deauthentication method: RADIUS
  • Roles tab
    • Role by Switch Role: Yes
      • registration: Registration
      • guest: Guest

6.15. Extricom

6.15.1. EXSW Wireless Switches (Controllers)

In order to have the Extricom controller working with PacketFence, you need to define two ESSID definition, one for the "public" network, and one for the "secure" network. This can be done under a very short time period since Extricom supports RADIUS assigned VLANs out of the box.

You first need to configure you RADIUS server. This is done under the: WLAN Settings → RADIUS tab. Enter the PacketFence RADIUS server information. For the ESSID configuration. in the administration UI, go to WLAN Settings → ESSID definitions. Create the profiles per the following:

Public SSID
  • MAC Authentication must be ticked
  • Encryption method needs to be set to None
  • Select PacketFence as the MAC Authentication RADIUS server (previously added)
Secure SSID
  • Encryption method needs to be set to WPA Enterprise/WPA2 Enterprise
  • AES only needs to be selected
  • Select PacketFence as the RADIUS server (previously added)

The final step is to enable SNMP Agent and SNMP Traps on the controller. This is done under the following tab in the administrative UI: Advanced → SNMP.

6.16. Fortinet FortiGate

This section shows how to configure a 802.1X SSID on a Fortigate 50E running on FortiOS 5.4.

You will need to have the CLI access on the Fortigate to do the configuration.

6.16.1. RADIUS

6.17. Hostapd

6.17.1. Introduction

This section will provide an example for the configuration of an open SSID (not encrypted) and a secure SSID (802.1X). You will need to install wpad and hostapd. These two SSIDs will do RADIUS authentication against PacketFence. You can not have both SSID configured on the same access point at the same time, there is a limitation with the DAE server.

6.17.2. Assumptions

  • You have a configured PacketFence environment with working test equipment
  • The management IP of PacketFence will be 192.168.1.10 and has s3cr3t as its RADIUS shared secret
  • You have an access point with OpenWrt Chaos Calmer 15.05 installed

6.17.3. Quick installation

Packages Installation

You can install the packages from the web interface of OpenWrt.

Go to System → Software

First update the repos by clicking the button Update lists if it’s not up to date.

Then you will have to install the packages of Hostapd and wpad.

Go to the tab 'Available packages' and then search for the package hostapd into the 'Filter:' field.

Click Install the hostapd-common package, the actual version is 2015-03-25-1.

Do the same process for the wpad package version 2015-03-25-1.

You will need the packages hostapd-common and wpad if they are not installed by default.
Dynamic VLAN Configuration

Connect using SSH to the AP and create the file : /etc/config/hostapd.vlan

* wlan0.#
Hostapd Configuration

You will need to modify the hostapd script that comes with the package that we previously installed.

Connect using SSH to the AP and run these commands:

cd /lib/netifd/
mv hostapd.sh hostapd.sh.old
opkg install curl
curl --insecure https://github.com/inverse-inc/packetfence/tree/devel/addons/hostapd/hostapd-15.05.sh > hostapd.sh
wifi
Configure the SSIDs

To configure the PF-Open SSID, we will edit the file /etc/config/wireless:

# Definition of the radio
config wifi-device 'radio0'
option type 'mac80211'
option channel '11'
option hwmode '11g'
option path 'pci0000:00/0000:00:00.0'
option htmode 'HT20'
# Configuration of the Open SSID
option device 'radio0'
option mode 'ap'
option vlan_file '/etc/config/hostapd.vlan'
option vlan_tagged_interface 'eth0'
option vlan_naming '0'
option dynamic_vlan '2'
option auth_port '1812'
option auth_server '192.168.1.10'
option auth_secret 's3cr3t'
option acct_port '1813'
option acct_server '192.168.1.10'
option acct_secret 's3cr3t'
option dae_port '3799'
option dae_client '192.168.1.10'
option dae_secret 's3cr3t'
option nasid 'Lobby'
option encryption 'none'
option ssid 'OpenWRT-Open'

Configure the PF-Secure SSID:

# Definition of the radio
config wifi-device 'radio0'
option type 'mac80211'
option channel '11'
option hwmode '11g'
option path 'pci0000:00/0000:00:00.0'
option htmode 'HT20'
config wifi-iface
option device 'radio0'
option mode 'ap'
option vlan_file '/etc/config/hostapd.vlan'
option vlan_tagged_interface 'eth0'
option vlan_naming '0'
option dynamic_vlan '2'
option auth_port '1812'
option auth_server '192.168.1.10'
option auth_secret 's3cr3t'
option acct_port '1813'
option acct_server '192.168.1.10'
option acct_secret 's3cr3t'
option dae_port '3799'
option dae_client '192.168.1.10'
option dae_secret 's3cr3t'
option nasid 'Lobby'
option encryption 'wpa2'
option ssid 'OpenWRT-Secure'

In order to apply this configuration, when you are connected using SSH on the AP, run the command 'wifi'. It will reload the configuration and broadcast the SSID. If you want to debug, you can use the command 'logread'.

It’s known that you can’t put 2 SSIDs with the same dae server at the same time. The deauthentication will not work on the second SSID.
PacketFence Configuration

Log in to the PacketFence administration web page and go under Configuration → Policies and Access Control → Switches → Add switch.

Definition:

  • IP Address/MAC Address/Range (CIDR): IP of your access point
  • Type: Hostapd
  • Mode: production
  • Deauthentication Method: RADIUS
  • Dynamic Uplinks: Checked

Roles:

  • Role by VLAN ID: Checked
  • Registration: Your registration VLAN ID
  • Isolation: Your isolation VLAN ID

RADIUS:

  • Secret Passphrase: s3cr3t

Save this configuration by clicking the 'Save' button.

Troubleshoot

There are few things you can do/check to see if your configuration is working.

To check the wireless configuration: uci show wireless or cat /etc/config/wireless

To check if your configuration (depend on the equipment) is correctly set into the Hostapd configuration file: cat /var/run/hostapd-phy0.conf

6.19. Meraki

To add the AP on PacketFence use the internal IP of the AP.

The 'Disconnect port' field must be set to '1700'.

6.19.1. WebAuth

In this section, we will cover the configuration of the Meraki controller to use Web authentication.

While using the WebAuth mode on the Meraki controller, you need to use "Role mapping by Switch Role" and "Role by Web Auth URL" in the tab 'Roles' from the switch configuration.

Configure your SSID as shown below:

Security and RADIUS configuration
Network configuration
It is mandatory that you use the Airespace-ACL-Name as "RADIUS attribute specifying group policy name".

The switch module to use for this configuration is "Meraki cloud controller V2".

Next, configure the roles for the devices on your network. Go in 'Network-wide→Group policies', then you will be able to create policies that can be configured as roles in the switch configuration of PacketFence. Creation of the policy Guest:

Group policies

Your configuration for the tab "Roles" in PacketFence will look like the following:

PacketFence role configuration
PacketFence URL configuration

URL in registration field should be in the form: 'http://<your_captive_portal_ip>/Meraki::MR_v2'

6.19.2. VLAN enforcement

This section will cover how to configure the Meraki WiFI controller to use with VLAN enforcement, use the configuration in the section WebAuth for the SSID.

In the configuration of PacketFence, use "Role by VLAN ID" and fill your VLANs matching roles.

PacketFence role configuration

6.19.3. Dynamic PSK (Pre-Shared Key)

This section will cover how to configure the Meraki WiFI controller to use with Dynamic PSK with PacketFence.

You will be able to attribute one PSK per user to use on every device they want. There is a common key to connect to a given PSK secured SSID to register and you will have an option to provision your device with that configuration on Windows, Apple and Android devices.

Create the SSID

Connection Profile configuration
Connection Profile configuration
Switch MS220-8
You should already have one port setup as Uplink, using a mode trunk, with at least your Registration and Production VLAN allowed on it.

The Meraki switch offer configuration for VLAN enforcement only.

You will need to access the Meraki dashboard to configure your switch. When you reach it you will need first to create a policy. You can create a "MAC authentication bypass" or a "802.1X" policy. Depending if you want to authenticate user via dot1x or MAB. You cannot combine both neither use a fallback mode on the same port, each port with a policy applied will be exclusive to MAB or dot1x.

To access the policy creation go to 'Switch→Access policies' in the Meraki dashboard menu. From there create a new policy, use the example below to create your policy.

Access policies

You now need to apply one of your policies to ports. To do so, go to 'Switch→Switch ports' and chose your options. To add a policy you created earlier, select it in the drop down list in Access policy. You need to configure the port in "mode access", the default access VLAN is not important if your VLANs are properly configured on PacketFence.

Switch Ports
RADSEC

It is possible to use RADSEC between Meraki and PacketFence in order to perform RADIUS over TCP and encrypted using TLS. Before performing the steps outlined in this section, make sure you have a working SSID using normal unencrypted RADIUS by following the steps in the sections above

Then, in order to enable RADSEC, go in your SSID configuration and under 'RADIUS proxy', select 'Use Meraki proxy' and save the settings.

After saving, check the RADSEC checkbox and save your settings.

Now, on your PacketFence server, you must add the Meraki CA root to the trusted Certificate Authorities of FreeRADIUS when performing RADSEC. You should download the Meraki CA certificate from here http://changeme.com/meraki-root.crt and append it to the content of /usr/local/pf/raddb/certs/ca.pem on your PacketFence server.

Next, restart radiusd to reload the CA certificates using:

# /usr/local/pf/bin/pfcmd service radiusd restart
RADSEC is done over port 2083 so make sure your server is available via a public IP address for this port and allows connections from your Meraki cloud controller. Refer to the Meraki documentation for details.

6.20. Mikrotik

PacketFence supports MikroTik’s RouterOS to provide wireless 802.1X (WPA2-Enterprise and MAC-based authentication) as well as wired 802.1X (EAPoL (Extensible Authentication Protocol over LAN)).

MikroTik has supported wireless 802.1X RADIUS disconnect for 2+ years, but this is not available for wired 802.1X (dot1x).

This configuration has been tested on a variety of MikroTik devices, including RB433AH, hAP ac, hAP ac lite, RB1100, RB3011 and various CCR devices. MikroTik provide free software updates ('/system package update install' and then '/sys routerboard upgrade' after booting new RouterOS).

Default MikroTik de-auth method has been changed to RADIUS, instead of SSH. Change 'my $default = $SNMP::RADIUS;' back to 'my $default = $SNMP::SSH;' if you want to continue using SSH as the de-authentication method.

EAPoL (802.1X) wired authentication has been available since v6.46 (Dec 2019) with MAB fallback being stable in v6.48.3.

PS: Don’t forget to use the pf account to ssh on the Access Point, to receive the ssh key, if you switch back to using SSH.

WPA2-EAP (WPA2 Enterprise) 802.1X SSID with MAC-based authentication on WPA2-PSK SSID

In this example the 2.4 and 5 GHz radios are configured to provide wireless 802.1X with a virtual AP being added to provide MAC-based authentication on a WPA2-PSK SSID where the password is disclosed as part of the SSID. Although the Pre-Shared Key (PSK) is published each wireless client’s connection would still be encrypted with a dynamically generated key.

First we create the SSIDs and virtual AP for the second SSID:

/interface wireless security-profiles

PS: VLAN 3999 is purposefully bogus, to ensure no access without VLAN assignment in the RADIUS response.

Next we create a VLAN filtering bridge:

/interface bridge
add name=bridge vlan-filtering=yes
/interface bridge port
add bridge=bridge interface="wlan1 - 2.4 GHz - ACME WiFi"
add bridge=bridge interface="wlan2 - 5 GHz - ACME WiFi"
add bridge=bridge interface="wlan1 - 2.4 GHz - ACME Guest"
add bridge=bridge interface="wlan2 - 5 GHz - ACME Guest"
/interface bridge vlan
add bridge=bridge tagged="bridge,wlan1 - 2.4 GHz - ACME WiFi,wlan2 - 5 GHz - ACME WiFi,wlan1 - 2.4 GHz - ACME Guest,wlan2 - 5 GHz - ACME Guest" vlan-ids=52
add bridge=bridge tagged="bridge,wlan1 - 2.4 GHz - ACME WiFi,wlan2 - 5 GHz - ACME WiFi,wlan1 - 2.4 GHz - ACME Guest,wlan2 - 5 GHz - ACME Guest" vlan-ids=666
add bridge=bridge tagged="bridge,wlan1 - 2.4 GHz - ACME WiFi,wlan2 - 5 GHz - ACME WiFi,wlan1 - 2.4 GHz - ACME Guest,wlan2 - 5 GHz - ACME Guest" vlan-ids=667

Next we create the VLANs and assign IPs:

/interface vlan
add comment="Guest WiFi:" interface=bridge name=vlan52 vlan-id=52
add comment="PacketFence - Registration:" interface=bridge name=vlan666 vlan-id=666
add comment="PacketFence - Isolation:" interface=bridge name=vlan667 vlan-id=667
/ip address
add address=172.16.20.1/24 interface=bridge
add address=10.239.239.1/24 interface=vlan52
add address=192.168.10.225/28 interface=vlan666
add address=192.168.10.241/28 interface=vlan667
PS: 172.16.20.1 is essentially assigned to VLAN 1 (untagged)

Last settings on the MikroTik defines PacketFence as the RADIUS server and filters traffic on Guest, Registration and Isolation networks:

/radius
add address=172.16.5.17 comment=packetfence: secret=useStrongerSecret service=wireless src-address=172.16.20.1 timeout=1s
/radius incoming
set accept=yes
/ip dhcp-relay
add dhcp-server=172.31.31.1 disabled=no interface=vlan666 local-address=192.168.10.225 add-relay-info=yes name="PacketFence - Registration"
add dhcp-server=172.31.31.129 disabled=no interface=vlan667 local-address=192.168.10.241 add-relay-info=yes name="PacketFence - Isolation"
/ip firewall address-list
add address=10.0.0.0/8 list=local
add address=172.16.0.0/12 list=local
add address=192.168.0.0/16 list=local
/ip firewall filter
add action=reject chain=forward comment="Limit WiFi - Guest:" dst-address=!41.1.1.1 dst-address-list=local in-interface=vlan52
add action=reject chain=forward comment="Limit PacketFence - Registration:" dst-address=!172.31.31.1 in-interface=vlan666
add action=reject chain=forward comment="Limit PacketFence - Isolation:" dst-address=!172.31.31.129 in-interface=vlan667
PS: Use 'src-address' to originate requests from an IP other than the one associated with the interface that routes towards PacketFence.
172.31.31.1 is PacketFence's routed registration network IP and 172.31.31.129 is the routed Isolation IP.

PacketFence switch configuration:

/usr/local/pf/conf/switches.conf

6.20.1. Wired 802.1X with MAB (MAC authentication bypass)

MikroTik calls this dot1x and is documented in more detail here: https://help.mikrotik.com/docs/display/ROS/Dot1X

The configuration requires a VLAN filtering bridge with Spanning Tree Protocol enabled. New bridges by default have RSTP (Rapid Spanning Tree Protocol) enabled, so you can follow similar steps as above for wireless 802.1X.

Set the PacketFence RADIUS server to be used for dot1x:

/radius
add address=172.16.5.17 comment=packetfence: secret=useStrongerSecret service=dot1x src-address=172.16.20.1 timeout=1s

Add the ethernet ports to the bridge:

/interface bridge port
add bridge=bridge interface=ether2
add bridge=bridge interface=ether3
add bridge=bridge interface=ether4
add bridge=bridge interface=ether5
PS: We use ether1 as our uplink, so we exclude it from the bridge.

Lastly we enable 802.1X for those interfaces, with MAB fallback:

/interface dot1x server
add auth-types=dot1x,mac-auth interface=ether2 interim-update=15m
add auth-types=dot1x,mac-auth interface=ether3 interim-update=15m
add auth-types=dot1x,mac-auth interface=ether4 interim-update=15m
add auth-types=dot1x,mac-auth interface=ether5 interim-update=15m

6.20.2. Open SSID

In this setup we use the interface ether5 for the bridge (Trunk interface) and ether1 as the management interface.

Configure your access point with the following configuration:

/interface wireless
# managed by CAPsMAN
# channel: 5180/20-Ce/an(17dBm), SSID: OPEN, local forwarding
set [ find default-name=wlan1 ] band=5ghz-a/n channel-width=20/40mhz-Ce disabled=no l2mtu=1600 mode=ap-bridge ssid=MikroTik-05A64D
/interface ethernet
set [ find default-name=ether1 ] name=ether1-gateway
set [ find default-name=ether2 ] name=ether2-master-local
set [ find default-name=ether3 ] master-port=ether2-master-local name=ether3-slave-local
set [ find default-name=ether4 ] master-port=ether2-master-local name=ether4-slave-local
set [ find default-name=ether5 ] name=ether5-master-local
/interface vlan

/ip accounting
set enabled=yes
/radius
add address=192.168.1.5 secret=useStrongerSecret service=wireless
/radius incoming
set accept=yes

6.20.3. Webauth

You can use webauth (external captive portal) on Mikrotik APs. In order to do so, you will have to activate the hotspot feature in the AP configuration as well as modify the redirection template so that it points to PacketFence.

First, you must establish an FTP connection to your access point and replace the content of hotspot/login.html with the following:

<html>
<head><title>...</title></head>
<body>
$(if chap-id)
<noscript>
<center><b>JavaScript required. Enable JavaScript to continue.</b></center>
</noscript>
$(endif)
<center>If you are not redirected in a few seconds, click 'continue' below<br>
<form name="redirect" action="http://192.168.1.5/Mikrotik" method="get">
<input type="hidden" name="mac" value="$(mac)">
<input type="hidden" name="ip" value="$(ip)">
<input type="hidden" name="username" value="$(username)">
<input type="hidden" name="link-login" value="$(link-login)">
<input type="hidden" name="link-orig" value="$(link-orig)">
<input type="hidden" name="error" value="$(error)">
<input type="hidden" name="chap-id" value="$(chap-id)">
<input type="hidden" name="chap-challenge" value="$(chap-challenge)">
<input type="hidden" name="link-login-only" value="$(link-login-only)">
<input type="hidden" name="link-orig-esc" value="$(link-orig-esc)">
<input type="hidden" name="mac-esc" value="$(mac-esc)">
<input type="hidden" name="ap-id" value="AP_IP_ADDRESS_HERE">
<input type="submit" value="continue">
</form>
<script language="JavaScript">
<!--
document.redirect.submit();
//-->
</script></center>
</body>
</html>

Next, in the login.html you have just uploaded, make sure you change AP_IP_ADDRESS_HERE by the management IP address of your access point and 192.168.1.5 by the IP address of your PacketFence captive portal.

Now, you must configure the hotspot feature on your AP. This configuration is done on top of an existing SSID you have previously configured which is on interface wlan1. Adjust the interface name if needed.

/ip hotspot
setup
hotspot interface: wlan1
local address of network: 10.5.50.1/24
masquerade network: yes

Set pool for HotSpot addresses

address pool of network: 10.5.50.2-10.5.50.254

Select hotspot SSL certificate

select certificate: none

Select SMTP server

ip address of smtp server: 0.0.0.0

Setup DNS configuration

dns servers: 8.8.8.8

DNS name of local hotspot server

dns name: myhotspot

Create local hotspot user

name of local hotspot user: admin
password for the user:

Next, you need to allow access to the PacketFence portal in the hotspot access list. Change 192.168.1.5 with the IP address you pointed to in login.html

/ip hotspot walled-garden
add dst-host=192.168.1.5
add src-address=192.168.1.5
/ip hotspot walled-garden ip
add action=accept disabled=no dst-host=192.168.1.5
add action=accept disabled=no src-address=192.168.1.5

Now, you will also need to configure the hotspot to point to your PacketFence RADIUS server:

/radius
add address=192.168.1.5 secret=useStrongerSecret service=hotspot
/ip hotspot profile
add hotspot-address=10.5.50.1 name=hsprof1 use-radius=yes

Next, you need to configure PacketFence to use webauth for this Access Point using the following switches.conf configuration. Change AP_IP_ADDRESS_HERE by the IP address you’ve put in login.html.

[AP_IP_ADDRESS_HERE]
VlanMap=Y
RoleMap=N
mode=production
ExternalPortalEnforcement=Y
type=Mikrotik
radiusSecret=useStrongerSecret
registrationVlan=-1

6.22. Meru

6.22.1. Meru Controllers (MC)

In this section, we cover the basic configuration of the Meru wireless controller for PacketFence via the web GUI.

Disable PMK Caching

If you are running a WPA2 SSID, you may need to disable PMK caching in order to avoid deauthentication issues. This is true if you are running AP 300s using any 5.0 versions including 5.0-87, or any versions below 4.0-160.

Here are the commands to run to disable the PMK caching at the AP level. First, login the AP, and run this command to see which radios are broadcasting your SSID. vap display

Second, disable the PMK caching on those radios. radio pmkid radio00 disable

You can also add those commands to the AP bootscript. Contact your Meru support representative for that part.

VLAN Definition

Here, we create our PacketFence VLANs for client use. Go to Configuration → Wired → VLAN, and select Add.

  • VLAN Name is the human readable name (ie. RegistrationVLAN)
  • Tag is the VLAN ID
  • Fast Ethernet Interface Index refers to the controller’s ethernet interface
  • IP Address – An IP address for this controller on this VLAN
  • Netmask – Network mask for this VLAN
  • IP Address of the default gateway – Wired IP router for this VLAN
  • Set the Override Default DHCP server flag to off
  • Leave the DHCP server IP address and the DHCP relay Pass-Through to default

Click OK to add the VLAN.

AAA Authentication Server

Here, we create our PacketFence RADIUS server for use. Under Configuration → Security → Radius, select Add.

  • Give the RADIUS Profile a name
  • Write a description of the profile
  • Give the RADIUS IP, RADIUS Secret and the RADIUS authentication port
  • Select Colon for the MAC address delimiter
  • Select MAC Address as the password type

Click OK to add the RADIUS profile.

AAA Accounting Server

Here, we create our PacketFence RADIUS server for use. Under Configuration → Security → Radius, select Add.

  • Give the RADIUS Profile a name
  • Write a description of the profile
  • Give the RADIUS IP, RADIUS Secret and the RADIUS accounting port
  • Select Colon for the MAC address delimiter
  • Select MAC Address as the password type

Click OK to add the RADIUS accounting profile.

AAA Profiles – Open SSID

Here, we create our wireless security profiles for use. Under Configuration → Security → Profile, select Add.

  • Give the security profile a name
  • Select Clear as the L2 Modes Allowed
  • Leave Data Encrypt empty
  • Disable the Captive Portal
  • Enable the Mac Filtering

Click OK to save the profile.

MAC Filtering

When using the OpenSSID, you need to activate the mac filtering. Under Configuration → Mac Filtering:

  • Set ACL Environment State to Permit list enabled
  • Select your RADIUS profile
AAA Profiles – Secure SSID

Here, we create our wireless security profiles for use. Under Configuration → Security → Profile, select Add.

  • Give the security profile a name
  • Select WPA2 as the L2 Modes Allowed
  • Select CCMP-AES for Data Encrypt
  • Select your PacketFence RADIUS Authentication Profile
  • Disable the Captive Portal
  • Enable the 802.1X network initiation
  • Leave the Mac Filtering to off

Click OK to save the profile.

WLAN SSIDs

Here, we create our SSID and tie it to a security profile. Under Configuration → Wireless → ESS, select Add.

  • Give the ESS profile a name, and enable it
  • Write an SSID name
  • Select your security profile name previously created
  • Select your PacketFence RADIUS Accounting Profile (if you want to do accounting)
  • Enable the SSID Broadcast
  • Make the new AP to join the ESS
  • Set the tunnel interface type to RADIUS and Configured VLAN
  • Select the registration VLAN for the VLAN Name

Click OK to create the SSID. Repeat those steps for the open and secure SSID by choosing the right security profile.

WLAN SSIDs – Adding to access point

Here, we tie our SSIDs to access points. Under Configuration → Wireless → ESS, select the SSID you want to add to your aps. Then, select the ESS-AP Table, and click Add.

  • Select the AP ID from the drop down list
  • Click OK to associate the SSID with this AP
Roles (Per-User Firewall)

Since PacketFence 3.3.0, we now support roles (per-user firewall rules) for the Meru hardware. To add firewall rules, go in Configuration → QoS System Settings → QoS and Firewall Rules. When you add a rule, you have to pay attention to two things:

  • The rule is applied to the controller physical interface right away, so make sure you are not too wide on your ACL to lock you out!
  • The rules are grouped using the Firewall Filter ID (We will use this ID for the roles)

So, since the matching is done using the Firewall Filter ID configuration field, your roles line in switches.conf would look like :

roles=Guests=1;Staff=2
You need to have the Per-User Firewall license in order to benefit this feature.

6.23. Mojo Networks

PacketFence supports SSIDs configured with 802.1X and Web Authentication

6.23.1. Create the RADIUS Profile

First, create a RADIUS Profile for PacketFence.

Click the 'Save' button to save the AP configuration.

Clone the newly created switch and enter 192.0.2.254 or the MAC address of the AP.

6.24. Motorola

In order to have the Motorola RFS controller working with PacketFence, you need to define two Wireless LANs definition, one for the "public" network, and one for the "secure" network.

6.24.1. WiNG (Firmware >= 5.0)

AAA Policy (RADIUS server)

First, we need to build the AAA Policy. Under Configuration → Wireless → AAA Policy, click on the Add button at the bottom right. Configure the RADIUS profile like the following:

  • Host: Choose IP Address in the drop down, and put the RADIUS server (PF) IP
  • Insert a RADIUS secret passphrase
  • Select "Through Wireless Controller" Request Mode
Since we are using RADIUS Dynamic Authorization, we need to enable the RADIUS accounting. Under the RADIUS accounting tab, click the Add button at the bottom right, and insert the proper values.
Open SSID

Under Configuration → Wireless → Wireless LANs, click on the Add button at the bottom right. Under Basic Configuration:

  • Profile Name : Give a convenient name
  • SSID: This is the ESSID name
  • Ensure that the WLAN Status is set to enable
  • Select Single VLAN as VLAN assignment technique
  • Ensure that "Allow RADIUS Override" is selected
Security configuration:
  • Select MAC as authentication type
  • Select your AAA Policy previously created
  • Ensure that you selected Open as the Encryption
Accounting configuration:
  • Make sure you select "Enable RADIUS Accounting"
  • Select the previously configured AAA Policy
Advanced configuration:
  • Make sure you select RADIUS Dynamic Authorization
Secure SSID

Under Configuration → Wireless → Wireless LANs, click on the Add button at the bottom right. Under Basic Configuration:

  • Profile Name : Give a convenient name
  • SSID: This is the ESSID name
  • Ensure that the WLAN Status is set to enable
  • Select Single VLAN as VLAN assignment technique
  • Ensure that "Allow RADIUS Override" is selected
Security configuration:
  • Select EAP as authentication type
  • Select your AAA Policy previously created
  • Ensure that you selected WPA/WPA2-TKIP as the Encryption
  • Unselect everything under Fast Roaming (Disable caching)
Accounting configuration:
  • Make sure you select "Enable RADIUS Accounting"
  • Select the previously configured AAA Policy
Advanced configuration:
  • Make sure you select RADIUS Dynamic Authorization
Profile (WLAN Mapping)

You have multiple options here. Either, you create a general AP profile, and you assign it to your Aps, or you modify the AP device configuration to map the WLAN to the radio interfaces. For the purpose of this document, we will modify the general profile. Under Profiles → default-apXXX (where XXX is your AP model), in Interface → Radios, edit the existing radios settings. Go to the WLAN Mapping tab, select the two SSIDs and click on the << button.

Profile (Management)

Here, we can configure our SNMP community strings. Located in Configuration → Management → Management Policy. Again, you can modify the default one, or you can create a brand new Policy.

VLANs

You need to ensure that the uplink interface of the controller is configured as a trunk, and that all the necessary VLANs are created on the device. This is configured under Device → rfsXXXX-MAC (where XXXX is your controller series, and MAC is the latest 3 octets of its mac address). Edit the device configuration, and go to Interface → Ethernet Ports. Ensure that the up1 interface is set as trunk, with all the allowed VLANs. Next, create the VLAN under Interface → Virtual Interfaces.

Roles (Per-User Firewall)

Since PacketFence 3.3.0, we now support roles for the Motorola hardware using WiNGS 5.x. To add roles, go in Configuration → Security → Wireless Client Roles. First create a global policy that will contain your roles. Next, create your Roles by clicking on the Add button on the bottom right. It is important to configure the Group Configuration line properly by setting the string name that we will use in the RADIUS packet. For example, for a Guests Role, you can put Group Configuration Exact Guests, and for a Staff Roles, you can put Group Configuration Exact Staff. In the roles configuration in switches.conf, you would have something like :

roles=CategoryGuests=Guests;CategoryStaff=Staff

Finally, don’t forget to configure the appropriate firewall rules for your Roles! Make sure also to commit the configuration upon your changes.

You need to have an Advanced Security license to enable the Per-User Firewall feature.
WIPS

In order to enable the WIPS functionality on the Motorola, you need to follow this procedure. The steps have been done using the CLI.

First, Create a wips-policy:

wips-policy Rogue-AP
history-throttle-duration 86400
event ap-anomaly airjack
event ap-anomaly null-probe-response
event ap-anomaly asleap
event ap-anomaly ad-hoc-violation
event ap-anomaly ap-ssid-broadcast-in-beacon
event ap-anomaly impersonation-attack
ap-detection

Next, create an event policy:

event-system-policy PF-WIDS
event wips wips-event syslog off snmp on forward-to-switch off email off

Next, create or adjust your management policy to configure the SNMP traps. Here is an example policy, please note the two last lines:

management-policy default
no http server
https server
ssh
user admin password 1 e4c93663e3356787d451312eeb8d4704ef09f2331a20133764c3dc3121f13a5b role superuser access all
user operator password 1 7c9b1fbb2ed7d5bb50dba0b563eac722b0676b45fed726d3e4e563b0c87d236d role monitor access all
no snmp-server manager v3
snmp-server community public ro
snmp-server community private rw
snmp-server user snmpoperator v3 encrypted des auth md5 0 operator
snmp-server user snmptrap v3 encrypted des auth md5 0 motorola
snmp-server user snmpmanager v3 encrypted des auth md5 0 motorola
snmp-server enable traps
snmp-server host 10.0.0.100 v2c 162

You then need to tell your controller to use the event policy:

rfs6000 5C-0E-8B-17-F2-E3
...
use event-system-policy PF-WIDS

Finally, you need to configure a radio interface on your AP to act as a sensor. Here is an example configuration for a dual-radio AP650:

ap650 00-23-68-86-EB-BC
use profile default-ap650
use rf-domain default
hostname ap650-86EBBC
country-code ca
use wips-policy Rogue-AP
interface radio1
rf-mode sensor
channel smart
power smart
data-rates default
no preamble-short
radio-share-mode off
interface radio2
...

6.24.2. Older Firmwares (< 5.0)

Option for Public Wireless LAN
  • Check the Dynamic Assignment check-box
  • Select "MAC Authentication" under Authentication
  • Click "Config…​" choose the Colon delimiter format
  • Un-check all encryption options

Add the two Read-Only and Read-Write users under Management Access → SNMP Access.

6.25. Ruckus

AAA Servers

We need to define the RADIUS and RADIUS accounting (mandatory):

Under Configuration → AAA Servers, click on the Create New button. Enter the proper configuration:

  • Enter a server name
  • Select either RADIUS or RADIUS accounting as the type
  • Use PAP as the Auth Method
  • Enter the IP address, and shared secret.
  • Hit OK

Repeat the steps for the RADIUS and RADIUS accounting types. We need 1 definition for each otherwise RADIUS dynamic authorization won’t work.

WLAN Definitions

Under Configuration → WLAN, click on the Create New button. Enter the proper configuration:

Open SSID
  • Enter a Name/SSID
  • Select Standard Usage as the Type
  • Select MAC Address as the authentication type
  • Select Open as the encryption method
  • Select the proper RADIUS server as the authentication server
  • Select the proper RADIUS server as the accounting server
The Open SSID does NOT support dynamic VLAN assignments on older versions of ZoneDirector (Firmware 9.3.0.0.83) but newer versions (Firmware 9.10.0.0.218 or newer) do support it.
Secure SSID
  • Enter a Name/SSID
  • Select Standard Usage as the Type
  • Select WPA2 as the authentication type
  • Select AES as the encryption method
  • Select the proper RADIUS server as the authentication server
  • Select the proper RADIUS server as the accounting server
  • Check the Enable Dynamic VLAN checkbox

WIPS

To enable the WIPS feature of the Ruckus in order to send SNMP traps to PacketFence, the setup is fairly simple.

First, configure the controller to send the traps to PacketFence. Under Configure → System → Network Management → SNMP Trap:

*Select "Enable SNMP Trap" *Put the PacketFence Management IP in the Trap Server IP field

The traps will arrive with the "public" community string

Next, you need to configure the Alarm Settings. Under Configure → Alarm Settings, make sure the following are selected:

*Rogue AP Detected *SSID-Spoofing AP Detected *MAC-Spoofing AP Detected *LAN Rogue AP Detected

Finally, enable the WIPS feature on the controller. Under Configure → WIPS → Intrusion Detection and Prevention, make sure both box are selected, click Apply.

6.25.1. Web Authentication

In order to use PacketFence as an external captive portal for web authentication, you will need to configure first your RADIUS authentication and accounting server (see steps above).

Hotspot configuration

Configure the Hotspot service profile to redirect devices to your PacketFence portal. Go on the ZoneDirector administration web page to the section Configure→Hotspot Services→Create New

Hotspot Service
1 - Name of your Hotspot service
2 - Login Page: Url of PacketFence portal interface (http://192.168.1.5/Ruckus)
3 - Start Page: redirect to the following URL: http://192.168.1.5
4 - Authentication Server: Select the PacketFence authentication RADIUS server (default port 1812)
5 - Accounting Server: Select the PacketFence accounting RADIUS server (default 1813)
6 - Click on the Walled Garden and authorize the IP of PacketFence management interface

Save your configuration.

WLAN configuration

Go to Configure → WLANs → WLANs → Create New

Hotspot Service
1 - Name of your SSID
2 - Type: Hotspot Service (WISPr)
3 - Authentication Method: Open
4 - Encryption Method: None
5 - Hotspot Services: Your hotspot service name that you configured
6 - Access VLAN: The VLAN ID that should be assigned to devices after authentication

Save your configuration.

PacketFence configuration

On the ZoneDirector configuration in PacketFence, you will need to specify -1 as the registration VLAN in order to display the captive portal to the end device.

You will need to deactivate the force secure redirect on the captive portal under Configuration → Captive Portal → Secure redirect → Unchecked

The captive portal needs to listen on the management interface, so you will need to add the portal daemon to the management interface under Configuration → Interfaces → Management Interface

Example:

[interface eth0]
ip=192.168.1.5
type=management,portal
mask=255.255.255.0

To apply the configuration, restart PacketFence using the following command: service packetfence restart

6.25.2. Ruckus Roles

Roles Configuration

Ruckus allows you to define roles. These roles link all users to the internal WLAN and permit access to all WLAN by default. You can still limit access to certain WLAN. Additionally, these roles can be used to apply per-user rate-limits and ACLs in newer versions of the Zone Director firmware, specifying also advanced options like Application Recognition Policies, URL filtering profiles, Etc.

To create a new user Role:

1 - Go to _Admin & Services -> System -> Roles_. The Roles page appears, displaying a Default role in the Roles table.
2 - Click Create New.
3 - Enter a Name and a short Description for this role.
4 - Choose the options for this role from the following:
Group Attributes: Fill in this field only if you are creating a user role based on Group attributes extracted from an Active Directory server. Enter the User Group name here. Active Directory/LDAP users with the same group attributes are automatically mapped to this user role.
Allow All WLANs: You have two options: (1) Allow Access to all WLANs, or (2) Specify WLAN Access. If you select the second option, you must specify the WLANs by clicking the check box next to each one.

The images below show the steps needed for Ruckus Unleashed.

Ruckus Roles
Create new role

If using ZoneDirector, then the steps are very similar as shown below:

To create a new user Role:

1 - Go to _Services & Profiles -> Roles_. The Roles and Policies page appears, displaying a Default role in the Roles table.
2 - Click Create New.
3 - Enter a Name and a short Description for this role.
4 - Choose the options for this role from the following:
Group Attributes: Fill in this field only if you are creating a user role based on Group attributes extracted from an Active Directory server.
Enter the User Group name here. Active Directory/LDAP users with the same group attributes are automatically mapped to this user role.
Allow All WLANs: You have two options: (1) Allow Access to all WLANs, or (2) Specify WLAN Access. If you select the second option, you
must specify the WLANs by clicking the check box next to each one. Don't enable the "Guest Pass" or "Administration" options as these
allow users with the given Roles to get administrative access to the ZoneDirector console.
5 - Additionally, you can enable the "Role Based Access Control Policy" option which is the most interesting one from PacketFence's point of view,
since this allows specific PF roles to receive specific ACLs, Different rate limits, thus further enhancing the value of Packetfence.
6 - Looking at the RBAC Policy options one can define the following:
OS type: Limit access based on operating system/device type.
VLAN: Assign a VLAN ID to this role. (This can be overriden directly from PacketFence if using the _Role by VLAN ID_ option)
Rate Limiting: Limit per-station uplink and downlink speeds.
L3/L4/IP address ACL: Apply a Layer 3/Layer 4/IP address ACL to this role.
Application Recognition & Control: Apply an application policy to this role.
Time Range: Limit the time range during which this role will be allowed to access the WLAN.
7 - Finally, if using the RBAC feature in ZoneDirector, make sure to enable the RBAC functionality for the WLAN created before:
To do this, edit the WLAN, expand the Advanced Options, and enable the check box next to Enable Role Based Access Control Policy in the Access Control section.
Ruckus Roles creation
Ruckus Roles RBAC configuration
Ruckus WLAN RBAC settings
PacketFence Configuration

On the PacketFence side you need to use role by switch role and add the same name as in the Group Attribute you created on the Ruckus side.

When a device connects to the SSID, PacketFence will return a VLAN identifier and a RuckusUserGroup attribute and if the role is allowed on the WLAN then the device will be authorized on the WLAN. Additionally, if RBAC is in use, the specific upstream/downstream rate limits, L2/L3 ACLS and Application Recognition Policies will be applied to the specific user, having the possibility of, for instance, giving different user Roles different access speeds. In case that the role is not allowed on the WLAN then the device will not be allowed to connect.

6.26. Ruckus SmartZone

Ruckus SmartZone is extremely flexible and allows for very different deployment scenarios, with the controller being an "on-premise" appliance managing a single tenant as well as a cloud-hosted solution where multiple tenants can share a single SmartZone instance by using its "managed partner domains" capabilities (For SmartZone-Highscale). As such, when it comes to AAA capabilities, the RADIUS connection between Ruckus and PacketFence supports two modes of operation: PROXY mode and non-PROXY mode.

In Proxy Mode, all RADIUS connections are done between SmartZone and PacketFence. In this mode, the RADIUS interface supports the use of Disconnect and CoA messages sent from PacketFence (the RADIUS server) to SmartZone (The RADIUS client). If proxy mode is used, it is highly recommended to have SmartZone deployed locally in the LAN together with PacketFence as otherwise, it might be needed to open specific ports (RADIUS COA/Disconnect ports) for PacketFence to be able to reach SmartZone if SmartZone is in a cloud scenario. Additionally, this would also mandate PacketFence to be hosted behind a static public IP, which is not always the case for certain business ISPs, as this IP would need to be configured in SmartZone as the target RADIUS IP.

In non-PROXY mode, though, the AP can send the RADIUS Access Request directly to PacketFence. This allows for SmartZone to be hosted in a public cloud. In this case, though, only an immediate response to the Access Request message can be issued by PacketFence and accepted by the AP. As clients can be roaming betwen APs, RADIUS CoA or Disconnect messages are not supported since the client might no longer be connected to the targetted AP. In this case, PacketFence must rely insted in the WISPr web services to trigger a disconnection / VLAN move after authentication.

In short, if you’re hosting a SmartZone appliance (physical or virtual) inside your LAN and PacketFence and SmartZone can talk directly without extraneous port-maps, use the PROXY mode for RADIUS as its much simpler. But if using a shared or external SmartZone server while keeping PacketFence local to your LAN, then you’ll probably have to opt for the NON-PROXY mode.

6.26.2. SmartZone configuration

First, you will need to define your RADIUS server in Configuration → Service and Profiles → Authentication. In newer versions (at least Firmware 3.6) make sure to select the proper RADIUS model (proxy or non-proxy according to your deployment details as described above)

Create your server using the following information (where 192.168.1.5 is the IP address of your PacketFence management interface):

  • 'IP Address:' 192.168.1.5
  • 'Port': 1812
  • 'Secret': useStrongerSecret

Then, in Configuration → Service and Profiles → Accounting, create a server with the following information:

  • 'IP Address:' 192.168.1.5
  • 'Port': 1813
  • 'Secret': useStrongerSecret

After, create a Hotspot in Configuration → AP Zones → Your Zone → Hotspot WISPr → Create New. Adjust 192.168.1.5 to the IP address of your portal.

Ruckus SmartZone Hotspot

Then, still on this page, in the 'Walled Gardens', make sure you add the portal IP address in this list.

Next, you will need to configure your WLAN to use the Hotspot authentication and point it to PacketFence. Also ensure you set 'Use the controller as a proxy'.

Ruckus SmartZone SSID

Now, you should configure the Northbound API of the SmartZone so PacketFence can communicate with it. In order to do so, go in Configuration → System → Northbound Portal Interface (Can be called "WISPr Northbound Interfaces" in newer versions of SmartZone) and set the 'Password' and save it. Keep the password closeby as it will be required for the PacketFence configuration. In this example, it will be passwordForNorthboundAPI. In case you’re using a SmartZone High-scale, you can define a northbound username/password for each Managed Domain so that each of your customers can have their own credentials. In this case, define both a username and password and keep both closeby.

In order to receive the information not encrypted in the URL, you will need to connect on the Ruckus SmartZone controller using SSH and do the following command:

no encrypt-mac-ip

6.26.3. PacketFence configuration

In PacketFence, add a new switch in Configuration → Switches with the following configuration:

  • Definition → External Portal Enforcement should be enabled
  • Definition → Type: Ruckus SmartZone Wireless Controller
  • Definition → Mode: production
  • Definition → Controller IP Address: IP address of SmartZone controller
  • Roles → Role by VLAN ID should be enabled
  • Roles → registration VLAN: -1
  • Roles → Role by Switch Role can be optionally enabled (see below)
  • RADIUS → Secret passphrase: useStrongerSecret
  • Web Services → Username: usernameForNorthboundAPI
  • Web Services → Password: passwordForNorthboundAPI

The Web Services Username is optional and only needed if using the "Managed Partner Domains" feature of SmartZone with multiple different Northbound API credentials (one per SmartZone domain). Additionally, for troubleshooting purposes, one can define the Web Services → Transport to HTTP instead of the default HTTPS so as to simplify troubleshooting by capturing the traffic between PacketFence and SmartZone.

6.26.4. Mac Authentication

For MAC authentication you have two options. Using SmartZone as a proxy RADIUS server (where all RADIUS requests are sent between the SmartZone controller and PacketFence directly) and non-radius RADIUS where the APs send RADIUS messages directly to PacketFence. This non-proxy scenario is useful when both the APs and PacketFence are "inside the LAN" but the SmartZone controller is in the WAN (for example, hosted in a commercial cloud provider). In this case, direct communication between SmartZone and PacketFence might not be possible as the WAN IP for PacketFence might be dynamic.

6.26.6. SmartZone configuration

First, you will need to define your RADIUS server in Service and Profiles → Authentication. Then select the "Proxy (SZ Authenticator)" tab and then select the zone for which you want to create the AAA server.

Create your server using the following information (where 192.168.1.5 is the IP address of your PacketFence management interface):

  • 'Name' : PacketFence-Auth
  • 'Service Protocol': RADIUS
  • 'IP Address:' 192.168.1.5
  • 'Port': 1812
  • 'Secret': useStrongerSecret
Ruckus SmartZone Proxy RADIUS Authentication

Then, in Service and Profiles → Accounting. Then select the "Proxy" tab and then select the zone for which you want to create the AAA server. Create the server using the information below:

  • 'Name' : PacketFence-Acct
  • 'IP Address:' 192.168.1.5
  • 'Port': 1813
  • 'Secret': useStrongerSecret

Give both authentication and accounting services an easily identifiable name such as "PacketFence-Auth" and "Packerfence-Acct". This names are purely for identification purposes only.

You can now create an SSID with OPEN/MAC athentication.

In the Wireless LANs top level menu , from the System tree hierarchy, select the Zone where you want to create a WLAN and then click Create.

Enter the name and SSID, then for Authentication Type select "Standard Usage" and for Method select "MAC Address".

Ruckus SmartZone Create Open WLAN with MAC authentication

The rest of the authentication options can be left "as-is" (The default MAC Address Format of "aabbccddeeff" should work fine)

For the Authentication & Accounting Service enable the "Use controller as proxy" checkbox for both Authentication and Accounting and select the previously created Authentication and Accounting profiles. (PacketFence-Auth and PacketFence-Acct respectively if you used the names suggested above)

Finally in the Advanced Options section, under Access VLAN section, make sure to enable the Enable Dynamic VLAN (AAA Override) checkbox is enabled so that the client receives a VLAN assigned by PacketFence.

6.26.7. PacketFence configuration

In PacketFence, add a new switch in Configuration → Switches with the following configuration:

  • Definition → External Portal Enforcement should NOT be enabled
  • Definition → Type: Ruckus SmartZone Wireless Controller
  • Definition → Mode: production
  • Definition → Use CoA: Can be enabled
  • Definition → Controller IP Address: IP address of SmartZone controller
  • Definition → CoA Port: 3799
  • Roles → Role by VLAN ID should be enabled
  • Roles → registration VLAN: Your registration VLAN ID
  • Roles → isolation VLAN: Your isolation VLAN ID
  • Roles → Role by Switch Role can be optionally enabled (see below)
  • RADIUS → Secret passphrase: useStrongerSecret

6.26.8. Non-PROXY mode

For non-proxy MAC authentication, repeat the same configuration as for PROXY mode but create the Authentication and Accounting servers under the "Non-Proxy (AP Authenticator)" menu. Additionally, configure the "WISPr northbound credentials" as for the Webauth section. Only the username / password is required, no other configuration is needed (portals, etc)

6.26.9. PacketFence configuration

In PacketFence, add a new switch in Configuration → Switches with the following configuration:

  • Definition → External Portal Enforcement should NOT be enabled
  • Definition → Type: Ruckus SmartZone Wireless Controller
  • Definition → Mode: production
  • Definition → Deauthentication Method: HTTPS
  • Definition → Controller IP Address: IP address of SmartZone controller
  • Roles → Role by VLAN ID should be enabled
  • Roles → registration VLAN: Your registration VLAN ID
  • Roles → isolation VLAN: Your isolation VLAN ID
  • Roles → Role by Switch Role can be optionally enabled (see below)
  • RADIUS → Secret passphrase: useStrongerSecret
  • Web Services → Transport: HTTPS
  • Web Services → Username: usernameForNorthboundAPI
  • Web Services → Password: passwordForNorthboundAPI

During troubleshooting, you can change the Deauth method and Web Services Transport to HTTP instead of HTTPS can capture the traffic destined to the SmartZone’s IP on port 9080 to inspect the WISPr API calls if needed.

For NON-PROXY Auth mode when using MAC-Authenticatin we need to set the "Deauthentication Method" to HTTP or HTTPS since this will force the disconnect message to be sent using the Northbound WISPr API instead of RADIUS Disconnect / CoA. If the Deauthentication Method is not set, then the code will try to use RADIUS by default and fail to disconnect the user.

6.26.10. Ruckus Roles

Roles Configuration

Ruckus SmartZone allows you to define roles for RBAC purposes. They can be used to apply per-user rate-limits and ACLs in newer versions of the SmartZone firmware, specifying also advanced options like Application Recognition Policies, URL filtering profiles, (Firwewall profiles)

To create and be able to use the role, we need to perform several steps:

1 - Create a _User Traffic Profile_
2 - Create a matching _User Role_
3 - Reference the User Role in the RADIUS Authentication server

The detailed steps are as follow:

Go to Services & Profiles → Access Control on the left menu and then click on the User Traffic tab. On this page, optionally select a Domain/Zone, click the "Create" button and give the new UTP name. Define any additional parameters such as Uplink/Downlink rate limits, define any ACLs you might want for that role and also select, if needed, an Application Recognition and Control policy and URL Filtering Control policies.

Ruckus SmartZone Create a User Traffic Profile

Next, go to Clients → Users & Roles menu and select the User Roles tab. On this page, optionally select a Domain/Zone, click the "Create" button and give the new User Role a name. This name is purely for identification only and its not the RADIUS attribute. You can choose any meaningful name. You should also select the User Traffic Profile defined in the previous step as well as, optionallu, a Firewall Profile.

Ruckus SmartZone Create a User Role

Finally, under Configuration → Service and Profiles → Authentication, select the RADIUS server created previously (Either in Proxy or NON-Proxy mode). Then, under the User Role Mapping section, click on Create.

Ruckus SmartZone Add User Role Mappings to RADIUS server

A new window will open where we can create a "User Traffic Profile Mapping". Under Group Attribute Value enter the string that will be sent from PacketFence (Configured under the Switch configuration in the "Role by Switch Role" section). This string must match between PacketFence and SmartZone and is the string sent in the RADIUS reply under the Ruckus-User-Group VSA. Then, under the "User Role", select the previously created User Role.

Ruckus SmartZone Add User Role Mappings to RADIUS server

Repeat all the steps above for as many different roles as needed. Keep in mind that you can define different roles on SmartZone than those on PacketFence. For example, on SmartZone you might have roles calles "10Mbps", "20Mbps" and so one (related to the specific rate limits assigned to the users) and then in PacketFence, assign the "10Mbps" SmartZone role to the "Students" and "Guests" PacketFence Roles, and the "20Mbps" SZ role to "Faculty" and "IT" PF roles.

PacketFence Configuration

On the PacketFence side you need to use role by switch role and add the same name as in the Group Attribute you created on the Ruckus side.

So when a device connects to the SSID, PacketFence will return a VLAN identifier and a RuckusUserGroup attribute and the device will be authorized on the WLAN on the specific VLAN. Additionally, if RBAC is in use, the specific upstream/downstream rate limits, L2/L3 ACLS and Application Recognition Policies will be applied to the specific user, having the possibility of, for instance, giving different user Roles different access speeds.

6.27. Trapeze

In order to have the Trapeze controller working with PacketFence, you need to define the RADIUS configuration and the proper service profiles.

RADIUS configuration

set radius server PF address 192.168.1.5 timeout 5 retransmit 3 deadtime 0 key secret
set server group PF-RADIUS members PF

Service Profiles

Here we define two service profiles, one for the open SSID (PacketFence-Public) and one for the WPA2-Enterprise SSID (PacketFence-Secure):

set service-profile PF-Open ssid-name PacketFence-Public
set service-profile PF-Open ssid-type clear
set service-profile PF-Open auth-fallthru last-resort
set service-profile PF-Open cipher-tkip enable
set service-profile PF-Open auth-dot1x disable
set service-profile PF-Open 11n mode-na required
set service-profile PF-Open attr vlan-name WLAN_REG
set service-profile PF-Secure ssid-name PacketFence-Secure
set service-profile PF-Secure cipher-tkip enable
set service-profile PF-Secure cipher-ccmp enable
set service-profile PF-Secure wpa-ie enable
set service-profile PF-Secure rsn-ie enable
set service-profile PF-Secure 11n mode-na required
set service-profile PF-Secure attr vlan-name Wlan
set radio-profile default service-profile PacketFence-Public
set radio-profile default service-profile PacketFence-Secure

AAA configuration

Finally, we need to tie the service profiles with the proper AAA configuration.

set accounting dot1x ssid PacketFence-Secure ** start-stop PF-RADIUS
set accounting mac ssid PacketFence-Public * start-stop PF-RADIUS
set authentication mac ssid PacketFence-Public * PF-RADIUS
set authentication dot1x ssid PacketFence-Secure ** pass-through PF-RADIUS

6.28. Ubiquiti

6.28.1. Web Authentication

Unifi side

In order to configure web authentication (external captive-portal) on Ubiquiti access points, you must have access to a Unifi controller and your APs must be connected to it.

First, you must configure the guest policy. Go in Settings → hotspot → general and configure it as shown below:

Unifi web-auth policy

Next, you must allow the device to reach the portal. Go in Settings → hotspot → advanced and configure it as shown below:

Unifi web-auth policy

Make sure you enabled Enable Guest Portal, and that you’ve set External portal server.

You also need to enter the IP address of a portal enabled interface on the PacketFence server in Custom Portal. Then in the ACCESS CONTROL section, add that same IP address to the Pre-Authorization Access

Then, still in the settings, create or edit a new SSID with the following settings:

Unifi web-auth SSID

You need to ensure STUN protocol is allowed between access points and controller so that controller gets instant notifications from access points. That’s important to have a correct deauthentication mechanism.

PacketFence side

You have two choices to define the APs in PacketFence, by ip address (or range) or by MAC addresses.

By IP address:

If you decide to define the AP by ip then you will need to define the controller as a switch and define the Controller IP and Webservices information (Transport/Username/Password) in his configuration.

Then once done, restart pfcron service and run that to fill the PacketFence cache:

/usr/local/pf/bin/pfcmd pfcron ubiquiti_ap_mac_to_ip

And verify that you have an entry for each AP

/usr/local/pf/bin/pfcmd cache switch_distributed list

By MAC address:

Once this is done, you will need to define all your APs MAC addresses in the PacketFence switches with a configuration similar to this:

[00:11:22:33:44:55]
description=Ubiquiti AP
ExternalPortalEnforcement=Y
type=Ubiquiti::Unifi
controllerIp=1.2.3.4
wsTransport=HTTPS
wsUser=admin
wsPwd=admin

Where :

  • wsTransport is the protocol used to connect to port 8443 of the Unifi controller and should be HTTPS. This is configured in the 'Web Services' tab of the switch.
  • wsUser is a valid administrator username on your Unifi controller. This is configured in the 'Web Services' tab of the switch.
  • wsPwd is the password that is associated to the wsUser. This is configured in the 'Web Services' tab of the switch.
  • controllerIp is the IP address of your Unifi controller. This is configured in the 'Definition' tab of the switch.

6.28.2. VLAN Enforcement

In order to configure VLAN enforcement on the Unifi controller, you need first to configure a RADIUS profile, then a secure wireless network.

Important : You cannot reuse a VLAN ID for dynamic VLAN if it is set as a static value for another SSID on the same AP. So, if you have a SSID set to use VLAN 10, you cannot use VLAN ID 10 for RADIUS controlled VLAN users as those users will not get an IP address.

Open SSID

Create a open profile:

Unifi Open Profile
Unifi Open Profile
Secure SSID

Create a secured profile:

Unifi Secure SSID
Unifi Secure SSID
CoA Support

CoA support has been introduced in the new version of the controller (Tested on 5.13.10), so on access reevaluation if you selected RADIUS as disconnect method then PacketFence will try a CoA.

6.29. Xirrus

6.29.1. Xirrus WiFi Arrays

Xirrus Access Points can be configured to work with PacketFence quickly since Xirrus supports RADIUS assigned VLANs out of the box.

First, RADIUS server configuration. Set the RADIUS server to be PacketFence’s IP:

radius-server ! (global settings)
!
external
primary server 192.168.1.5
primary secret useStrongerSecret
!
accounting
primary server 192.168.1.5
primary secret useStrongerSecret
exit
exit
exit

Enable SNMP Agent on the access point:

snmp
!
v2
community read-write public
community read-only public
exit
!
exit

Finally, don’t forget to create the SSID you want and the proper bindings with the LAN. Open SSID should be configured to perform MAC Authentication and Secure SSID should be configured to perform 802.1X (WPA-Enterprise or WPA2-Enterprise).

External portal SSID
  • Set Encryption / Authentication to None / Open
  • Then check the WPR checkbox
  • Then in in the section Web Page Redirect Configuration set Server to External Login
  • Set the Redirect URL to http://192.168.1.5/Xirrus
  • Set the Redirect Secret to any passphrase of your choice
  • In the RADIUS Configuration section set the RADIUS server to point to your PacketFence server

7. VPN Configuration

7.1. Cisco ASA

7.1.1. AnyConnect

PacketFence supports Cisco ASA VPN with AnyConnect.

You can force VPN users to authenticate first on the captive portal and based on the role of the device allow it and/or set dynamic ACL.

In this example we assume that the Cisco ASA have 2 interfaces, one Management (192.168.2.1) where the VPN is activated and another one Registration (192.168.1.6) that is facing the PacketFence server (192.168.1.5).

Before trying to configure PacketFence with the Cisco ASA first be sure that when you connect with AnyConnect and when the VPN is up that your device is able to reach Internet.

7.2. OpenVPN

PacketFence support OpenVPN with PAP authentication.

7.2.1. OpenVPN server configuration

In this section we will cover the OpenVPN installation on a Debian 11 machine and how to configure it.

apt install libgcrypt20-dev openvpn easy-rsa
mkdir -p /etc/openvpn/server/certs
cd /etc/openvpn/server/certs
openssl genrsa -out ca.key 2048
openssl req -new -x509 -days 3650 -key ca.key -out ca.crt

Edit the server.conf file and paste this following content:

vim /etc/openvpn/server.conf

Next you need to compile the radius extention for openvpn:

wget https://github.com/ValdikSS/openvpn-radiusplugin/archive/refs/heads/master.zip
unzip master.zip
cd openvpn-radiusplugin-master

Then apply this patch:

diff -ruN openvpn-radiusplugin-master.orig/Config.cpp openvpn-radiusplugin-master/Config.cpp
--- openvpn-radiusplugin-master.orig/Config.cpp 2015-12-23 08:07:19.000000000 -0500

{

Compile the plugin:

make
cp radiusplugin.so /etc/openvpn/

Then edit the radiusplugin.cnf file:

vim /etc/openvpn/radiusplugin.cnf
NAS-Identifier=OpenVpn
Service-Type=5
Framed-Protocol=1
NAS-Port-Type=5
NAS-IP-Address=192.168.0.6

}

7.2.2. PacketFence configuration

On the PacketFence side the only thing you need to do is to create a new switch as type OpenVPN with the ip address 192.168.0.6 and with the shared secret 'secret'. And enable "CLI Access Enabled" in the switch too to enable the radius-cli to start.

1. Be careful to change the secret key to a much stronger one. A 16 character random secret with digits, upper case and lower case characters is recommended.
