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 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.
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.
