The HPE 3100 v2 switch provides four output queues per port. WRR assigns each queue a weight
value (represented by w3, w2, w1, or w0) to decide the proportion of resources assigned to the
queue.
On a 100 Mbps port, you can configure the weight values of WRR queuing to 5, 3, 1, and 1
(corresponding to w3, w2, w1, and w0, respectively). In this way, the queue with the lowest priority
can get a minimum of 10 Mbps of bandwidth. WRR avoids the disadvantage of SP queuing, where
packets in low-priority queues can fail to be served for a long time.
Another advantage of WRR queuing is that when the queues are scheduled in turn, the service time
for each queue is not fixed. If a queue is empty, the next queue will be scheduled immediately. This
improves bandwidth resource use efficiency.
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.
Configuring SP queuing
NOTE:
The congestion management settings on the HPE 3100 v2 switches are made in system view and
apply to all ports of the switch.
Configuration procedure
To configure SP queuing:
Step
1.
Enter system view.
2.
Configure SP queuing
on the switch.
3.
Display SP queuing
configuration.
