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

Conguring 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 EMC 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. Congure a password for the terminal line to which you
assign a method list that contains the line authentication method. Congure 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.
