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 privilege level one administrator if no authentication method is defined. A privilege level one administrator must authenticate to get to Privileged Exec mode. NOTE: Requests sent by the switch to a RADIUS server include the username "$enabx$", where x is the requested privilege level in decimal. For enable to be authenticated on RADIUS servers, add "$enabx$" users to them. The login user ID is also sent to TACACS+ servers for enable authentication. Example The following example configures enable authentication to use the enable method for accessing higher privilege levels. console(config)# aaa authentication enable default enable aaa authentication login Use the aaa authentication login command in Global Configuration mode to create and enable the authentication method required for administrative access to the switch. To return to the default configuration and optionally delete an authentication list, use the no form of this command. Syntax aaa authentication login {default | list-name} {method1 [method2...]} no aaa authentication login {default | list-name} • default - Uses the listed authentication methods that follow this argument as the default list of methods when an administrator logs in. • list-name - Character string used to name the list of authentication methods activated when an administrator logs in to the switch.
