aaa authentication enable "tacp" tacacs-server host 1.2.3.4 key "secret" exit line telnet login authentication tacplus enable authentication tacp exit The following describes each line in the above configuration: • The aaa authentication login "tacplus" tacacs command creates a login authentication list called "tacplus" that contains the method tacacs. If this method returns an error, the user will fail to login. • The aaa authentication enable "tacp" tacacs command creates an enable authentication list called "tacp" that contains the method tacacs. If this method fails, then the user will fail to execute the enable command. • The tacacs-server host 1.2.3.4 command is the first step in defining a TACACS+ server at IP address 1.2.3.4. The result of this command is to place the user in tacacs-server mode to allow further configuration of the server. • The key "secret" command defines the shared secret. This must be the same as the shared secret defined on the TACACS+ server. • The line telnet command enters the configuration mode for the telnet line. • The login authentication tacplus command assigns the tacplus login authentication method list to be used for users accessing the switch via telnet. • The enable authentication tacp command assigns the tacp enable authentication method list to be used for users executing the enable command when accessing the switch via telnet. NOTE: A user logging in with this configuration would be placed in User EXEC mode with privilege level 1. To access Privileged EXEC mode with privilege level 15, use the enable command.
