8.2 Priority Queuing
Priority Queuing (PQ) allows you to define how traffic is prioritized in the switch. There are 8 traffic priorities (0-7) and
4 internal queues. Each packet can be assigned a priority based on which port it comes in, 802.1P header, or IP
precedence/DSCP in IP header if the packet is an IP packet. The OQS configurations determine how priority is
assigned based on packet characteristics to cause the switch to place traffic into the four queues.
8.2.1 Priority Mapping
Each outgoing packets is assigned to one of the 4 internal queues. The assigned is based on the configuration of the
mapping between priorities and queues. The default mapping is as follows:
Priorities Queues
0 1
1 1
2 2
3 2
4 3
5 3
6 4
7 4.
The default setting implies that priority 0 is the lowest and 7 the highest.
