access-class access-list-name [ipv4 | ipv6]
NOTE: If you already have congured generic IP ACL on a terminal line, then you cannot further apply IPv4 or IPv6
specic ltering on top of this conguration. Similarly, if you have congured either IPv4 or IPv6 specic ltering on a
terminal line, you cannot apply generic IP ACL on top of this conguration. Before applying any of these congurations,
you must rst undo the existing conguration using the no access-class access-list-name [ipv4 | ipv6]
command.

Conguring 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 rst 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 password you assigned to the terminal line. Congure a password for the terminal line to which you
assign a method list that contains the line authentication method. Congure a password using the password
command from LINE mode.
local
Prompt for 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.
