4.5.12 QoS and CoS

4.5.12.1 802.1p Priority

Eight egress queues on all switch ports. These queues can either be configured

with the Weighted Round Robin (WRR) scheduling algorithm or configured with

one queue as a strict priority queue and the other queues for WRR. The strict

priority queue must be empty before the other queues are serviced. You can use

the strict priority queue for mission-critical and time-sensitive traffic. There are

three options:

First Come First Service: the first come frame has the highest priority
High First: Packetʼs priority depends on its CoS value
Weighted Round Robin (WRR): If WRR scheduling algorithm is enabled,

the ratio of the weights is the ratio of frequency in which the WRR scheduler

de-queues packets from each queue.
