• default - Uses the listed authentication methods that follow this argument as the default list of methods, when using higher privilege levels. • list-name - Character string used to name the list of authentication methods activated, when using access higher privilege levels. (Range: 1-12 characters) • method1 [method2...] - Specify at least one from the following table: Keyword enable line none radius tacacs Source or destination Uses the enable password for authentication. Uses the line password for authentication. Uses no authentication. Uses the list of all RADIUS servers for authentication. Uses the list of all TACACS+ servers for authentication. Default Configuration The default enable list is "enableList." It is used by console, telnet, and SSH and only contains the method none. Command Mode Global Configuration mode 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 listname 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. 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. 151
