Configure 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, FTOS 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.

Apply an ACL to a VTY line. ip access-class access-list LINE
FTOS Behavior: Prior to FTOS version 7.4.2.0, in order to deny access on a VTY line, you must apply an ACL and
AAA authentication to the line. Then users are denied access only after they enter a username and password.
Beginning in FTOS version 7.4.2.0, only an ACL is required, and users are denied access before they are
prompted for a username and password.
