7.7.12.1 802.1p Priority
Each port has eight egress queues. These queues can either be configured with the
Weighted Round Robin (WRR) scheduling algorithm or 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:
Packet’s 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.
