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
ƒ 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.
All eight queues are participating excluding the queues that are assigned as expedite queues. The weights of these queues are
ignored in the ratio calculation.
All eight queues participate in the WRR exclude the expedite queues, in which case the corresponded weight is ignored (not
used in the ratio calculation). The expedite queue is a priority queue, and it is serviced until empty before the other queues are
serviced.
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.
Example
The following example sets queue weights as follows:
ƒ Queue 1—6/36
ƒ Queue 2—6/36
ƒ Queue 3—6/36
ƒ Queue 4—6/36
