Usage Information
By default, the Enable password is used. If you configure aaa authentication enable default, the
system 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, the system employs the second method (or third
method, if necessary) automatically. For example, if the TACACS+ server is reachable, but the server key is
invalid, the system proceeds to the next authentication method. The TACACS+ is incorrect, but the user is still
authenticated by the secondary method.
