Chapter 10 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:
http://www.cisco.com/en/US/products/sw/iosswrel/ps1835/products_command_reference_book09186a
00800872ce.html
For more information about AV pairs, see RFC 3580, “802.1x Remote Authentication Dial In User Service
(RADIUS) Usage Guidelines.”
802.1x Readiness Check
Note To use 802.1x readiness check, the switch must be running the LAN base image.
The 802.1x readiness check monitors 802.1x activity on all the switch ports and displays information
about the devices connected to the ports that support 802.1x. You can use this feature to determine if the
devices connected to the switch ports are 802.1x-capable. You use an alternate authentication such as
MAC authentication bypass or web authentication for the devices that do not support 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 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 10-40.

1. The Framed-IP-Address AV pair is sent only if a valid Dynamic Host Control Protocol (DHCP) binding
exists for the host in the DHCP snooping bindings table.
