Mapping CoS Values to Egress Queues

This switch processes Class of Service (CoS) priority tagged traffic by using four
priority queues for each port, with service schedules based on strict or Weighted
Round Robin (WRR). Up to eight separate traffic priorities are defined in IEEE
802.1p. The default priority levels are assigned according to recommendations in
the IEEE 802.1p standard as shown in the following table.
