queue bandwidth

This command assigns weighted round-robin (WRR) weights to the eight

class of service (CoS) priority queues, or specifies a high-priority queue

when the queue mode is set to hybrid. Use the no form to restore the

default weights.

Syntax

queue bandwidth weight1...weight8

no queue bandwidth

weight1...weight7 - The ratio of weights for queues 0 - 7 determines

the weights used by the WRR scheduler. (Range: 0 - 15)

Default Setting

Weights 1, 2, 4, 6, 8, 10, 12, 14 are assigned to queues 0 - 7 respectively.

Command Mode

Interface Configuration (Ethernet, Port Channel)

Command Usage

• WRR controls bandwidth sharing at the egress port by defining

scheduling weights for allocated service priorities.

• Use queue weights 1-15 for queues allocated service time based on

WRR. Queue weights must be configured in ascendant manner,

assigning more weight to each higher numbered queue.

• Use queue weight zero for high-priority queues processed with strict

priority under the hybrid mode (see the queue mode command on

page 33-3). Set queue bandwidth to zero to indicate a high-priority

queue. Any of queues 2 - 7 can be specified as high-priority queues,

but the selected queues must be in consecutive order, and must all be

grouped toward the high end of the queue list as shown in the

following example.
