The device to which an ACL-based simplified traffic policy is applied matches packet characteristics with access control list (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 and then configure an ACL-based simplified traffic policy so that the device can filter, police, re-mark, count, mirror, or redirect packets matching ACL rules.
Compared with a common traffic policy, an ACL-based simplified traffic policy is easy to configure because you do not need to configure a traffic classifier, traffic behavior, or traffic policy independently. However, an ACL-based simplified traffic policy defines less matching rules than a common traffic policy because only ACL rules are used to match packets.
