Intel SBCEGBESW10 CLI manual Priority-queue out num-of-queues

QoS Commands

Default Configuration

The default WRR weight ratio is one-eighth of the sum of all queue weights (each weight is set to 6).

Command Mode

Interface Configuration (Ethernet, port-channel) mode

User Guidelines

Use the priority-queue out num-of-queuesGlobal Configuration mode command to configure a queue as WRR or Strict Priority. Use this command to define a WRR weight per interface.

The weight ratio for each queue is defined by the queue weight divided by the sum of all queue weights (i.e., the normalized weight). This sets the bandwidth allocation for each queue.

A queue can be assigned a WRR weight of 0, in which case no bandwidth is allocated to the queue and the shared bandwidth is divided among the remaining queues.

All eight queues participate in the WRR, excluding the queues that are assigned as expedite queues. The weights of the expedite queues are ignored in the ratio calculation.

An expedite queue is a priority queue, and it is serviced before the other queues are serviced. Use the priority-queue out Interface Configuration (Ethernet, port-channel) mode command to enable expedite queues.

Example

The following example assigns a weight of 6 to each of the 8 WRR queues.

Console(config-if)# wrr-queue bandwidth 6 6 6 6 6 6 6 6

priority-queue out num-of-queues

The priority-queue out num-of-queuesGlobal Configuration mode command configures the number of expedite queues. To return to the default configuration, use the no form of this command.

Syntax

priority-queue out num-of-queues number-of-queues
