Chapter 8 Configuring Switch-Based Authentication Controlling Switch Access with TACACS+ Step 3 Command aaa authentication login {default | list-name} method1 [method2...] Step 4 Step 5 line [console | tty | vty] line-number [ending-line-number] login authentication {default | list-name} Step 6 Step 7 Step 8 end show running-config copy running-config startup-config Purpose Create a login authentication method list. • To create a default list that is used when a named list is not specified in the login authentication command, use the default keyword followed by the methods that are to be used in default situations. The default method list is automatically applied to all ports. • For list-name, specify a character string to name the list you are creating. • For method1..., specify the actual method the authentication algorithm tries. The additional methods of authentication are used only if the previous method returns an error, not if it fails. Select one of these methods: • enable-Use the enable password for authentication. Before you can use this authentication method, you must define an enable password by using the enable password global configuration command. • group tacacs+-Uses TACACS+ authentication. Before you can use this authentication method, you must configure the TACACS+ server. For more information, see the "Identifying the TACACS+ Server Host and Setting the Authentication Key" section on page 8-13. • line-Use the line password for authentication. Before you can use this authentication method, you must define a line password. Use the password password line configuration command. • local-Use the local username database for authentication. You must enter username information in the database. Use the username password global configuration command. • local-case-Use a case-sensitive local username database for authentication. You must enter username information in the database by using the username name password global configuration command. • none-Do not use any authentication for login. Enter line configuration mode, and configure the lines to which you want to apply the authentication list. Apply the authentication list to a line or set of lines. • If you specify default, use the default list created with the aaa authentication login command. • For list-name, specify the list created with the aaa authentication login command. Return to privileged EXEC mode. Verify your entries. (Optional) Save your entries in the configuration file. To disable AAA, use the no aaa new-model global configuration command. To disable AAA authentication, use the no aaa authentication login {default | list-name} method1 [method2...] global configuration command. To either disable TACACS+ authentication for logins or to return to the default value, use the no login authentication {default | list-name} line configuration command.
