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 for queues 0 through 3
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.
