Usage Information
By default, the locally configured username password is used. If you configure aaa authentication login
default, the system uses the methods this command defines for login instead.
Methods configured with the aaa authentication login command are evaluated in the order they are
configured. If users encounter an error with the first method listed, the system applies the next method
configured. If users fail the first method listed, no other methods are applied. The only exception is the local
method. If the user’s name is not listed in the local database, the next method is applied. If the correct user name/
password combination is not entered, the user is not allowed access to the switch.
NOTE: 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.
After configuring the aaa authentication login command, configure the login authentication
command to enable the authentication scheme on terminal lines.
