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 Weighted Round
Robin (WRR). Up to 8 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.
