Configuring Login Authentication for Terminal Lines
You can use any combination of up to 6 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:
•
enable—Prompt for the enable password.
•
line—Prompt for the e password you assigned to the terminal line. You must configure a password for
the terminal line to which you assign a method list that contains the
line authentication method.
Configure a password using the command password from LINE mode.
•
local—Prompt for the the system username and password.
•
none—Do not authenticate the user.
•
radius—Prompt for a username and password and use a RADIUS server to authenticate.
•
tacacs+—Prompt for a username and password and use a TACACS+ server to authenticate.
To configure authentication for a terminal line, follow these steps:
VTY lines 0-2 use a single authentication method,
line (Figure 4-6).
Step Task Command Syntax Command Mode
1 Create 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.
aaa authentication login {method-list-name |
default} [method-1] [method-2] [method-3]
[method-4] [method-5] [method-6]
CONFIGURATION
2 Apply the method list from Step 1 to
a terminal line.
login authentication {method-list-name |
default}
CONFIGURATION
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.
