Repeat the steps if you have multiple items that you want in effect at different times.

Applying an IPv4 ACL to a Terminal Line

You can use numbered ACLs to control access to one or more terminal lines. You cannot apply named ACLs
to lines. You must set identical restrictions on all the virtual terminal lines because a user can attempt to
connect to any of them.
Follow these steps to restrict incoming and outgoing connections between a virtual terminal line and the
addresses in an ACL:
