◆
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)#
Related Commands

queue weight
This command assigns weights to the eight 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.
Syntax
queue weight weight0...weight7
no queue weight
weight0...weight7 - The ratio of weights for queues 0 - 7 determines the
weights used by the WRR scheduler. (Range: 1-15)
Default Setting
Weights 1, 2, 4, 6, 8, 10, 12, 14 are assigned to queues 0 - 7 respectively.

Command Usage
◆
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 602 ).
◆
Bandwidth is allocated to each queue by calculating a precise number of bytes
per second that will be serviced on each round.
