Overview of ACL-based Simplified Traffic Policies

Overview of ACL-based Simplified Traffic Policies

The device to which an ACL-based simplified traffic policy is applied matches packet characteristics with ACL rules and provides the same QoS for packets matching ACL rules, implementing differentiated services.

To control traffic entering a network, configure ACL rules to match information such as the source IP address, fragment flag, destination IP address, source port number, and source MAC address in packets. Then configure an ACL-based simplified traffic policy so that the device can filter, count, or redirect packets matching ACL rules.

Compared with a common traffic policy, an ACL-based simplified traffic policy is easy to configure. This is because you do not need to configure a traffic classifier, traffic behavior, or traffic policy independently. However, an ACL-based simplified traffic policy supports fewer matching rules than a common traffic policy because only ACL rules are used to match packets.
