Unusual Network Activity

The supplicant statistics listing shows multiple ports with the same

authenticator MAC address. The link to the authenticator may have been

moved from one port to another without the supplicant statistics having been

cleared from the first port. Refer to “Note on Supplicant Statistics” in the

chapter on Port-Based and User-Based Access Control in the Access Security

Guide for your switch.

The show port-access authenticator < port-list > command shows one or more

ports remain open after they have been configured with control

unauthorized. 802.1X is not active on the switch. After you execute aaa port-

access authenticator active, all ports configured with control unauthorized

should be listed as Closed.

Figure C-1. Authenticator Ports Remain “Open” Until Activated

RADIUS server fails to respond to a request for service, even though

the server’s IP address is correctly configured in the switch. Use

show radius to verify that the encryption key (RADIUS secret key) the switch

is using is correct for the server being contacted. If the switch has only a global

key configured, then it either must match the server key or you must configure

a server-specific key. If the switch already has a server-specific key assigned

to the server’s IP address, then it overrides the global key and must match the

server key.

Port A9 shows an “Open” status even

though Access Control is set to

Unauthorized (Force Auth). This is

because the port-access

authenticator has not yet been

activated.
