Configuring the Switch

CLI – The following sets the queue mode to strict priority service mode.

Console(config)#queue mode strict

4-151

Console(config)#exit

 

Console#show queue mode

4-151

Queue mode: strict

Console#

Setting the Service Weight for Traffic Classes

This switch uses the Weighted Round Robin (WRR) algorithm to determine the frequency at which it services each priority queue. As described in “Mapping CoS Values to Egress Queues” on page 3-100,the traffic classes are mapped to one of the four egress queues provided for each port. You can assign a weight to each of these queues (and thereby to the corresponding traffic priorities). This weight sets the frequency at which each queue will be polled for service, and subsequently affects the response time for software applications assigned a specific priority value.

Command Attributes

•WRR Setting Table* – Displays a list of weights for each traffic class (i.e., queue).

•Weight Value – Set a new weight for the selected traffic class. (Range: 1-255)

*CLI shows Queue ID.

Web – Click Priority, Queue Scheduling. Select the interface, highlight a traffic class (i.e., output queue), enter a weight, then click Apply.
