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