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 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.
The priority levels recommended in the IEEE 802.1p standard for
various network applications are shown in the following table.
However, you can map the priority levels to the switch's output
queues in any way that benefits application traffic for your own
network.
