You enable the expedite queues by using the priority-queue out interface configuration command
wrr-queue cos-map.
It is recommended to specifically map a single VPT to a queue, rather than mapping multiple VPTs to a
single queue
Example
The following example maps CoS 3 to queue 7.
Console (config)# wrr-queue cos-map 7 3
5.17.4 wrr-queue bandwidth
The wrr-queue bandwidth interface configuration command assigns Weighted Round Robin (WRR)
weights to egress queues. The weights ratio determines the frequency in which the packet scheduler
dequeues packets from each queue. To return to the default values, use the no form of this command.
Syntax
wrr-queue bandwidth weight1 weight2 ... weight_n
no wrr-queue bandwidth
weight1...weight_n—Sets the bandwidth ratio in which the WRR packet scheduler dequeues
packets. Separate each value by spaces. (Range: 6 - 255)
Default Configuration
The default WRR weight is 1/8 ratio for all queues (each weight set to 6).
Command Mode
Interface Configuration mode
User Guidelines
The packet refers to a threshold by the conformance level. Weighted round robin queues should be
defined on the interface.
Use the priority-queue out num-of-queues command to globally configure a queue as WRR or Strict
Priority.
Use this command to set a weight per interface.
The ratio will be like this:
The ratio for each queue is defined by the queue weight divided by the sum of all queue weights (i.e., the
normalized weight). This actually sets the bandwidth allocation of each queue.
A weight of 0 means no bandwidth is allocated for the same queue, and the share bandwidth is divided
among the remaining queues.
