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.
