Classification

Classifiers assign incoming unicast and multidestination (multicast, broadcast, and destination lookup fail) traffic to forwarding classes, so that different classes of traffic can receive different treatment. Classification is based on CoS bits, DSCP bits, EXP bits, a forwarding class (fixed classifier), or packet headers (multifield classifiers). Each classifier assigns all incoming traffic that matches the classifier configuration to a particular forwarding class. You cannot mix unicast and multidestination traffic in the same classifier or forwarding class.
