queue weight
This command assigns weights to the four class of service (CoS) priority
queues when using weighted queuing, or one of the queuing modes that
use a combination of strict and weighted queuing. Use the no form to
restore the default weights.

queue weight weight0...weight3
no queue weight
weight0...weight3 - The ratio of weights for queues 0 - 3
determines the weights used by the WRR scheduler. (Range: 1-255)

Weights 1, 2, 4, 6 are assigned to queues 0 - 3 respectively.

•
This command shares bandwidth at the egress port by defining
scheduling weights for Weighted Round-Robin, or for the queuing mode
that uses a combination of strict and weighted queuing ( page 1121 ).
•
Bandwidth is allocated to each queue by calculating a precise number
of bytes per second that will be serviced on each round.

The following example shows how to assign round-robin weights of 1 - 4 to
the CoS priority queues 0 - 3.
