Terminal Lines

You can access the system remotely and restrict access to the system by creating user profiles.
Terminal lines on the system provide different means of accessing the system. The console line (console) connects you through the console
port in the route processor modules (RPMs). The virtual terminal lines (VTYs) connect you through Telnet to the system. The auxiliary line
(aux) connects secondary devices such as modems.

Denying and Permitting Access to a Terminal Line

Dell Networking recommends applying only standard access control lists (ACLs) to deny and permit access to VTY lines.
• Layer 3 ACLs deny all traffic that is not explicitly permitted, but in the case of VTY lines, an ACL with no rules does not deny traffic.
• You cannot use the show ip accounting access-list command to display the contents of an ACL that is applied only to a
VTY line.
• When you use the access-class access-list-name command without specifying the ipv4 or ipv6 attribute, both IPv4 as
well as IPv6 rules that are defined in that ACL are applied to the terminal. This method is a generic way of configuring access
restrictions.
• To be able to filter access exclusively using either IPv4 or IPv6 rules, use either the ipv4 or ipv6 attribute along with the access-
class access-list-name command. Depending on the attribute that you specify (ipv4 or ipv6), the ACL processes either
IPv4 or IPv6 rules, but not both. Using this configuration, you can set up two different types of access classes with each class
processing either IPv4 or IPv6 rules separately.
To apply an IP ACL to a line, Use the following command.
• Apply an ACL to a VTY line.
LINE mode
access-class access-list-name [ipv4 | ipv6]
