AAA Commands
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.
Console(config)# aaa authentication login default radius local enable none
