2.7 Troubleshooting
A user always fails to pass the authentication implemented through TACACS+.
Do the following:
Check whether the correct user name and password and the available services
for the user have been configured on the TACACS+ server.
Check whether the TACACS+ server can be pinged, and whether the correct
address and port number and shared-key of the server have been configured on
the router.
Use the host command to reconfigure the TACACS+ server. Due to the failure in
communicating with the RADIUS server, the system regards the RADIUS server
as unavailable. In this case, you can use the undo host command to remove the
RADIUS server that has been configured, and then use the host command to
reconfigure the RADIUS server. Thus, the RADIUS server will be able to work
without any delay.
Check proper configurations have been made for the TACACS+ server and
whether the modifications just made have taken effect.
