A device with an ACL-based simplified traffic policy can match packet characteristics with ACLs, and provide the same QoS for packets that match ACL rules. This implements differentiated services.
To control traffic entering a network, configure an ACL to match information such as the source IP address, fragment flag, destination IP address, source port number, and source MAC address. Then, configure an ACL-based simplified traffic policy so that the device can filter packets that match ACL rules.
Compared with a traffic policy based on traffic classifiers, an ACL-based simplified traffic policy is easy to configure because there is no need to independently configure a traffic classifier, traffic behavior, or traffic policy. However, an ACL-based simplified traffic policy defines less matching rules than a traffic policy based on traffic classifiers.
