Weighted round-robin (WRR) scheduling: WRR scheduling requires
you to specify a number the indicates the importance (weight) of the queue
relative to other CoS queues. WRR scheduling prevents the low-priority
queues from being completely neglected during periods of high-priority
traffic. The WRR scheduling transmits some packets from each queue in
turn. The number of packets it sends corresponds to the relative importance
of the queue. For example, if one queue has a weight of 3 and another
has a weight of 4, three packets are sent from the first queue for every four
that are sent from the second queue. By using this scheduling, low-priority
queues have the opportunity to send packets even through the high-priority
queues are not empty. The valid value of weight is from 1 to 255 and weight
settings only effective for WRR scheduling.
Click OK to make the setting send to the switch (HTTP server). Click Reload to
refresh the settings to current value. To make the configuration effective, please
