Usage Information

By default, the Enable password is used. If you configure aaa authentication enable default, Dell EMC Networking OS uses the methods defined for Enable access instead.

Methods configured with the aaa authentication enable command are evaluated in the order they are configured. If authentication fails using the primary method, Dell EMC Networking OS employs the second method (or third method, if necessary) automatically. The fallback to the second method would happen only if the authentication failure is due to a non-reachable server or invalid TACACS server key. The fallback would not occur if the authentication failure is due to invalid credentials. For example, if the TACACS+ server is reachable, but the server key is invalid, Dell EMC Networking OS proceeds to the next authentication method.
