Configuring a queue scheduling profile
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 algorithms: SP, WRR, and WFQ. In a queue
scheduling profile, you can configure SP + WRR or SP + WFQ. When the three queue scheduling
algorithms are configured, SP queues, WRR groups, and WFQ groups are scheduled in descending
order of queue ID. 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, Figure 17
show the scheduling order for
SF cards.
Figure 17 SP + WRR queuing
• 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 3, queue 4, and queue 5 are scheduled according to their weights. When both queue 6
and queue 7 are empty, WRR group 1 is scheduled.
• Queue 1 and queue 2 are scheduled according to their weights. WRR group 2 is scheduled when
queue 7, queue 6, queue 5, queue 4, and queue 3 are all empty.
• Queue 0 has the lowest priority, and it is scheduled when all the other queues are empty.
