"defaultList" is used by the console and only contains the method none. "networkList" is used by telnet and SSH and only contains the method local. Command Mode Global Configuration mode 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. Example The following example configures authentication login. 192 AAA Commands
