Chapter 9 Configuring Switch-Based Authentication

Controlling Switch Access with TACACS+

	Command	Purpose
Step 3
	aaa authentication login {default	Create a login authentication method list.
	list-name}method1 [method2...]	• 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 9-13.
		• 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.
Step 4 line [console tty vty] line-number		Enter line configuration mode, and configure the lines to which you want
	[ending-line-number]	to apply the authentication list.
Step 5
	login authentication {default	Apply the authentication list to a line or set of lines.
	list-name}	• 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.
Step 6
	end	Return to privileged EXEC mode.
Step 7
	show running-config	Verify your entries.
Step 8
	copy running-config startup-config	(Optional) Save your entries in the configuration file.

To disable AAA, use the no aaa new-modelglobal 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.
