I think it list out all the protocols. For class-based weighted fair queueing (CBWFQ), you define traffic classes based on match criteria including protocols, access control lists (ACLs), input interfaces, QoS labels, and EXP field values. Packets satisfying the match criteria for a class constitute the traffic for that class. The match protocol command specifies the name of a protocol to be used as the match criteria against which packets are checked to determine if they belong to the class specified by the class map.
