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.
