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.
