Configuring queue scheduling profiles

In a queue scheduling profile, you can configure scheduling parameters for each queue. By applying the
queue scheduling profile to an interface, you can implement congestion management on the interface.
Queue scheduling profiles support three queue scheduling methods: SP, WRR, and WFQ. In a queue
scheduling profile, you can configure SP+WRR or SP+WFQ. When SP+WRR or SP+WFQ is configured,
the scheduling priority is as follows:
The SP group has higher priority than WRR groups and WFQ groups.
•
Queues in the SP group are scheduled in descending order of queue IDs.
•
WRR or WFQ groups are scheduled in the 1:1 ratio.
•
• In a WRR or WFQ group, queues are scheduled based on their weights.
When SP and WRR groups are configured in a queue scheduling profile,
order.
Figure 16 Queue scheduling profile configured with both SP and WRR
• Queue 7 has the highest priority. Its packets are sent preferentially.
Queue 6 has the second highest priority. Packets in queue 6 are sent when queue 7 is empty.
•
Queue 0 has the third highest priority, and it is scheduled when queue 7 and queue 6 are empty.
•
Queues 3 through 5 in WRR group 1 are scheduled according to their weights when queue 7,
•
queue 6, and queue 0 are empty.
