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 
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
Console(config-if)#switchport priority default 5
Console(config-if)#end
Console#show interfaces switchport ethernet 1/3
