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.
