Troubleshooting

Unusual Network Activity

Port-Based Access Control (802.1x)-Related Problems

Note To list the 802.1x port-access Event Log messages stored on the switch, use

show log 802.

See also “Radius-Related Problems” on page C-18.

The switch does not receive a response to RADIUS authentication

requests. In this case, the switch will attempt authentication using the

secondary method configured for the type of access you are using (console,

Telnet, or SSH).

There can be several reasons for not receiving a response to an authentication

request. Do the following:

■ Use ping to ensure that the switch has access to the configured RADIUS

servers.

■ Verify that the switch is using the correct encryption key (RADIUS secret

key) for each server.

■ Verify that the switch has the correct IP address for each RADIUS server.

■ Ensure that the radius-server timeout period is long enough for network

conditions.
