The default and optional list names created with the aaa authentication enable command are
used with the enable authentication command.

name
is any character string used to name this list. The
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. Note that enable will not succeed for a
level one user if no authentication method is defined. A level one user must authenticate to get
to privileged EXEC mode. For example, if none is specified as an authentication method after
radius, no authentication is used if the RADIUS server is down.
NOTE: Requests sent by the switch to a RADIUS server include the username "$enabx$", where x is the
requested privilege level. For enable to be authenticated on RADIUS servers, add "$enabx$" users to
them. The login user ID is now sent to TACACS+ servers for enable authentication.
Example
The following example sets authentication when accessing higher privilege levels.
console(config)# aaa authentication enable default enable
