Chapter 9 Configuring IEEE 802.1x Port-Based Authentication
Understanding IEEE 802.1x Port-Based Authentication
You can view the AV pairs that are being sent by the switch by entering the debug radius accounting
privileged EXEC command. For more information about this command, see the Cisco IOS Debug
Command Reference, Release 12.2 at this URL:

For more information about AV pairs, see RFC 3580, “IEEE 802.1X Remote Authentication Dial In User
Service (RADIUS) Usage Guidelines.”
Using IEEE 802.1x Authentication with VLAN Assignment
The switch supports IEEE 802.1x authentication with VLAN assignment. After successful IEEE 802.1x
authentication of a port, the RADIUS server sends the VLAN assignment to configure the switch port.
The RADIUS server database maintains the username-to-VLAN mappings, assigning the VLAN based
on the username of the client connected to the switch port. You can use this feature to limit network
access for certain users.
