1. The Framed-IP-Address AV pair is sent only if a valid Dynamic Host Control Protocol (DHCP) binding
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 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.
