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-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.

Example

The following example sets the queue mode to strict priority service mode:

Console(config)#queue mode strict

Console(config)#

queue bandwidth

This command assigns weighted round-robin (WRR) weights to the four class of service (CoS) priority queues. Use the no form to restore the default weights.

Syntax

queue bandwidth weight1...weight4 no queue bandwidth

weight1...weight4 - The ratio of weights for queues 0 - 3 determines the weights used by the WRR scheduler. (Range: 1 - 255)

Default Setting

Weights 1, 4, 16 and 64 are assigned to queue 0, 1, 2 and 3 respectively.
