Configuring Login Authentication for Terminal Lines

You can use any combination of up to six authentication methods to authenticate a user on a terminal line.
A combination of authentication methods is called a method list. If the user fails the first authentication method, Dell
Networking OS prompts the next method until all methods are exhausted, at which point the connection is terminated. The
available authentication methods are:
Prompt for the enable password.
enable
Prompt for the password you assigned to the terminal line. Configure a password for the terminal line to
line
which you assign a method list that contains the line authentication method. Configure a password using
the password command from LINE mode.
Prompt for the system username and password.
local
Do not authenticate the user.
none
Prompt for a username and password and use a RADIUS server to authenticate.
radius
Prompt for a username and password and use a TACACS+ server to authenticate.
tacacs+
1 Configure an authentication method list. You may use a mnemonic name or use the keyword default. The default
authentication method for terminal lines is local and the default method list is empty.
CONFIGURATION mode
aaa authentication login {method-list-name | default} [method-1] [method-2] [method-3]
[method-4] [method-5] [method-6]
2 Apply the method list from Step 1 to a terminal line.
CONFIGURATION mode
login authentication {method-list-name | default}
3 If you used the line authentication method in the method list you applied to the terminal line, configure a password for the
terminal line.
LINE mode
password
Example of Terminal Line Authentication
In the following example, VTY lines 0-2 use a single authentication method, line.
Dell(conf)#aaa authentication login myvtymethodlist line
Dell(conf)#line vty 0 2
Dell(config-line-vty)#login authentication myvtymethodlist
Dell(config-line-vty)#password myvtypassword
Dell(config-line-vty)#show config
