User Guidelines
The default and optional list names created with the aaa authentication
login command are used with the login authentication command. Create a
list by entering the aaa authentication login
list-name method
command for
a particular protocol, where
list-name
is any character string used to name
this list. The
method
argument identifies the list of methods that the
authentication algorithm tries, in the given sequence.
The additional methods of authentication are used only if the previous
method returns an error, not if there is an authentication failure. To ensure
that the authentication succeeds even if all methods return an error, specify
none as the final method in the command line. For example, if none is
specified as an authentication method after radius, no authentication is used
if the RADIUS server is down.
