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.
