Hi Waimen,

Each ethernet port on the 3550 has four egress queues, one of which can be the egress expedite queue. All four queues participate in the WRR unless the expedite queue is enabled, in which case, the fourth queue is ignored and not used in the ratio calculation. The expedite queue is a strict-priority queue, and it is serviced until empty before the other queues are serviced. You enable the expedite queue by using the priority-queue out interface configuration command.

Hope this helps!
