Configuring RADIUS Authentication and Accounting

Troubleshooting RADIUS Operation

Symptom Possible Cause

The switch does not receive a response to RADIUS authen-

tication 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 server.

• Verify that the switch is using the correct encryption key

for the designated server.

• Verify that the switch has the correct IP address for the

RADIUS server.

• Ensure that the radius-server timeout period is long

enough for network conditions.

• Verify that the switch is using the same UDP port number

as the server.

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 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.
