To list multiple TACACS+ servers to be used by the aaa authentication login command, configure this command multiple times.

If you are not configuring the switch as a TACACS+ server, you do not need to configure the port, timeout and key optional parameters. If you do not configure a key, the key assigned in the tacacs-server key command is used.

You can use duplicate host names or IP addresses among TACACS groups. However, you cannot use duplicate host names or IP addresses within the same TACACS group.

If a VRF is not configured on the TACACS group, then servers configured in the group are considered to be on the default VRF. TACACS servers that are configured in the CONFIGURATION mode are also considered to be on the default VRF.

For AAA servers to use a group of TACACS servers, you must explicitly configure the group using the aaa tacacs group group-namecommand. The order in which the TACACS servers are tried depends on the order in which they are configured.
