weighted round robin (WRR) and Weighted Random Early Detection (WRED) parameters.
You enable the expedite queues by using the priority-queue out interface configuration command wrr-queue cos-map.
It is recommended to specifically map a single VPT to a queue, rather than mapping multiple VPTs to a single queue

Console (config)# wrr-queue cos-map 7 3
