Command Usage
You can set the switch to service the queues based on a strict rule that
requires all traffic in a higher priority queue to be processed before lower
priority queues are serviced, or use Weighted Round-Ro bin (WRR) queuing
that specifies a relative weight of each queue. WRR u ses a pred efined re lative
weight for each queue that determines the pe rcentage of service tim e the
switch services each queue before moving on to the next queue. This
prevents the head-of-line blocking t hat can occur with strict priority queuing.
