User Guidelines

The ratio for each queue is defined as the queue weight divided by the sum of all

queue weights (the normalized weight). This sets the bandwidth allocation of each

A weight of 0 indicates that no bandwidth is allocated for the same queue, and the

shared bandwidth is divided among the remaining queues. It is not recommended

to set the weight of a queue to a 0 as it might stop transmission of

control-protocols packets generated by the device.

All queues participate in the WRR, excluding the expedite queues, whose

corresponding weight is not used in the ratio calculation.

An expedite queue is a priority queue, which is serviced until empty before the

other queues are serviced. The expedite queues are designated by the

priority-queue out num-of-queues
