Priority Commands (Layer 2)
– 859 –
response time for software applications assigned a specific priority
value.
◆ 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.
◆ 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)#

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: 1-15)

COMMAND USAGE
◆ 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).
◆ Bandwidth is allocated to each queue by calculating a precise number
of bytes per second that will be serviced on each round.
