Selecting the Queue Mode
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-Robin (WRR) queuing that specifies a relative
weight of each queue. WRR uses a predefined relative weight for each queue that
determines the percentage of service time the switch services each queue before
moving on to the next queue. This prevents the head-of-line blocking that can occur
with strict priority queuing.
Command Attributes
•
WRR
- Weighted Round-Robin shares bandwidth at the egress ports by using
scheduling weights 1, 2, 4, 6, 8, 10, 12, 14 for queues 0 through 7 respectively.
(This is the default selection.)
•
Strict
- Services the egress queues in sequential order, transmitting all traffic in the
higher priority queues before servicing lower priority queues.
Web
– Click Priority, Queue Mode. Select Strict or WRR, then click Apply.
