Creating a traffic class

In the traffic class-based configuration model, you use match criteria to create a class of IPv4 or IPv6 traffic and select the packets you want to manage. In a traffic class configuration, match criteria consist of match and ignore commands. These commands determine the packets that belong to a class. (Match/ignore criteria are modelled on the permit/deny criteria used in ACLs.)

The traffic classes you configure can be used later in the service policies you create for different software features, such as QoS and port mirroring. The match criteria used in match/ignore statements are the same across software features.
