Chapter 10 Configuring IEEE 802.1x Port-Based Authentication
Configuring 802.1x Authentication
Configuring VLAN ID-based MAC Authentication
Beginning in privileged EXEC mode, follow these steps:
There is no show command to confirm the status of VLAN ID-based MAC authenticati on. You can use
the debug radius accounting privileged EXEC command to confirm the RADIUS attribute 32. For more
information about this command, see the Cisco IOS Debug C ommand Reference, Release 12.2:
http://www.cisco.com/en/US/docs/ios/debug/command/reference/db_q1.html#wp1123741
This example shows how to globally enable VLAN ID-based MAC authentication on a switch:
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# mab request format attribute 32 vlan access-vlan
Switch(config-if)# exit
Configuring Flexible Authentication Ordering
Beginning in privileged EXEC mode, follow these steps:
This example shows how to configure a port attempt 802.1x authentication first, followed by web
authentication as fallback method:
Switch# configure terminal
Switch(config)# interface gigabitethernet2/0/1
Switch(config)# interface gigabitethernet0/1
Switch(config)# authentication order dot1x webauth
Command Purpose
Step 1 configure terminal Enter global configuration mode.
Step 2 mab request format attribute 32 vlan access-vlan Enable VLAN ID-based MAC authentication.
Step 3 copy running-config startup-config (Optional) Save your entries in the configuration
file.
Command Purpose
Step 1 configure terminal Enter global configuration mode.
Step 2 interface interface-id Specify the port to be configured, and enter interface
configuration mode.
Step 3 authentication order [dot1x | mab] |
{webauth}
(Optional) Set the order of authentication methods used on a port.
Step 4 authentication priority [dot1x | mab] |
{webauth}
(Optional) Add an authentication method to the port-priority list.
Step 5 show authentication (Optional) Verify your entries.
Step 6 copy running-config startup-config (Optional) Save your entries in the configuration file.
