Class of Service Configuration
3-147
CLI
– This example assigns a default priority of 5 to port 3.
Mapping CoS Values to Egress Queues
This switch processes Class of Service (CoS) priority tagged traffic by using eight
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.
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.
