User Guidelines
The default and optional list names created with the aaa authentication
enable command are used with the enable authentication command.
Create a list by entering the aaa authentication enable list-name method
command 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 authenticate the administrator. Only
the RADIUS or TACACS methods can return an error. For example, if none is
specified as an authentication method after radius, no authentication is used
if the RADIUS server is down.
