Troubleshooting AAA, RADIUS, and HWTACACS 915
Symptom 2: RADIUS packets cannot reach the RADIUS server.
Analysis:
■ The device fails to communicate with the RADIUS server (on physical layer or
link layer).
■ No IP address is assigned to the RADIUS server on the device.
■ The UDP ports for authentication/authorization and accounting are not
configured correctly.
Symptom 3: A user is authenticated and authorized, but accounting for the user
is not normal.
Analysis:
■ The accounting port is not correctly configured.
■ The accounting server and authentication/authorization server are not the
same equipment. However, the device requires that
authentication/authorization and accounting should be performed on the same
server (they should have the same IP address).
