The controlling policy against Telnet users is determined, including the source and
destination IP addresses to be controlled and the controlling actions (permitting or
denying).
Controlling Telnet users by source IP addresses is achieved by applying basic ACLs,
which are numbered from 2000 to 2999. For defining an ACL, refer to "Defining
Basic ACLs" on page 641.
