ACL overview
An access control list (ACL) is a set of rules (or permit or deny statements) for identifying traffic based on
criteria such as source IP address, destination IP address, and port number.
ACLs are primarily used for packet filtering. “
Packet filtering with ACLs “ provides an example. You can
use ACLs in QoS, firewall, routing, and other feature modules for identifying traffic. The packet drop or
forwarding decisions varies with the modules that use ACLs.
