Table 8-1
lists the AV pairs and when they are sent by the switch:
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

For more information about AV pairs, see RFC 3580, “IEEE 802.1X Remote Authentication Dial In User
Service (RADIUS) Usage Guidelines.”
Using 802.1x Readiness Check
The 802.1x readiness check monitors IEEE 802.1x activity on all the switch ports and displays
information about the devices connected to the ports that support IEEE 802.1x. You can use this feature
to determine if the devices connected to the switch ports are IEEE 802.1x-capable. You use an alternate
authentication such as MAC authentication bypass or web authentication for the devices that do not
support IEEE 802.1x functionality.
This feature only works if the supplicant on the client supports a query with the NOTIFY EAP
notification packet. The client must respond within the IEEE 802.1x timeout value.
For information on configuring the switch for the 802.1x readiness check, see the
“Configuring 802.1x
Readiness Check” section on page 8-23
