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.

Console(config)#interface ethernet 1/3

24-2

Console(config-if)#switchport priority default 5

31-4

Console(config-if)#end
Console#show interfaces switchport ethernet 1/3
