• The bandwidth percentage assigned to each flow is (precedence value of the flow + 1)/total assignable bandwidth quota. The bandwidth percentages for the flows are 1/15, 2/15, 3/15, 4/15, and 5/15, respectively. • The bandwidth assigned to a queue = the minimum guaranteed bandwidth + the bandwidth allocated to the queue from the assignable bandwidth. SP+WRR queuing You can assign some queues on a port to the SP scheduling group and the others to the WRR scheduling group (group 1) to implement SP + WRR queue scheduling. The switch schedules packets in the SP scheduling group preferentially, and when the SP scheduling group is empty, schedules the packets in the WRR scheduling group. Queues in the SP scheduling group are scheduled with the SP queue scheduling algorithm. Queues in the WRR scheduling group are scheduled with WRR. SP+WFQ queuing SP+WFQ queuing is similar to SP+WRR queuing. You can assign some queues on a port to the SP scheduling group and the others to the WFQ scheduling group to implement SP + WFQ queue scheduling. The switch schedules packets of queues in the WFQ group based on their minimum guaranteed bandwidth settings, then uses SP queuing to schedule the queues in the SP scheduling group, and at last uses WFQ to schedule the queues in the WFQ scheduling group in a round robin fashion according to their weights Configuring SP queuing Configuration procedure To configure SP queuing: Step 1.

The bandwidth percentage assigned to each flow is (precedence value of the flow + 1)/total
assignable bandwidth quota. The bandwidth percentages for the flows are 1/15, 2/15, 3/15,
4/15, and 5/15, respectively.

The bandwidth assigned to a queue = the minimum guaranteed bandwidth + the bandwidth
allocated to the queue from the assignable bandwidth.
SP+WRR queuing
You can assign some queues on a port to the SP scheduling group and the others to the WRR scheduling
group (group 1) to implement SP + WRR queue scheduling. The switch schedules packets in the SP
scheduling group preferentially, and when the SP scheduling group is empty, schedules the packets in the
WRR scheduling group. Queues in the SP scheduling group are scheduled with the SP queue scheduling
algorithm. Queues in the WRR scheduling group are scheduled with WRR.
SP+WFQ queuing
SP+WFQ queuing is similar to SP+WRR queuing. You can assign some queues on a port to the SP
scheduling group and the others to the WFQ scheduling group to implement SP + WFQ queue
scheduling. The switch schedules packets of queues in the WFQ group based on their minimum
guaranteed bandwidth settings, then uses SP queuing to schedule the queues in the SP scheduling group,
and at last uses WFQ to schedule the queues in the WFQ scheduling group in a round robin fashion
according to their weights
