Queue Bandwidth - SMC Networks SMC TigerStack III SMC6824M Management Manual

Command Mode
Global Configuration
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.
