Step 3 aaa authentication login {default |
list-name} method1 [method2...]Creates 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 you plan to use 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 3-18.
• 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
[ending-line-number]Enters line configuration mode, and configures the lines to which you
want to apply the authentication list.
Step 5 login authentication {default |
list-name}Applies 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.
Step 6 end Returns to privileged EXEC mode.
