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 it fails. To ensure that the authentication succeeds even if all methods return an error,
specify
none
as the final method in the command line.
Example
The following example configures the authentication login, so that user authentication is performed
as follows: Authentication is attempted at the RADIUS server. If the RADIUS server is not
available, authentication is attempted at the local user database. If there is no database, then no
authentication is performed.

method lists for accessing higher privilege levels. Use the no form of this command to return to the
