Priority Commands (Layer 2)
– 859 –
response time for software applications assigned a specific priority
value.
â—† Service time is shared at the egress ports by defining scheduling
weights for WRR, or for the queuing mode that uses a combination of
strict and weighted queuing. Service time is allocated to each queue by
calculating a precise number of bytes per second that will be serviced
on each round.
â—† The specified queue mode applies to all interfaces.
EXAMPLE
The following example sets the queue mode to strict priority service mode:
Console(config)#queue mode strict
Console(config)#

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: 1-15)

COMMAND USAGE
â—† This command shares bandwidth at the egress port by defining
scheduling weights for WRR, or for the queuing mode that uses a
combination of strict and weighted queuing (page 858).
â—† Bandwidth is allocated to each queue by calculating a precise number
of bytes per second that will be serviced on each round.
