SMC Networks SMC6750L2 manual Setting the Service Weight for Traffic Classes

CONFIGURING THE SWITCH

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 2-55,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.

Web – Open Priority/Queue Scheduling. Select a traffic class by clicking on it with your cursor, enter a weight value, and then click “Apply.”

CLI – The following example shows how to assign WRR weights of 1, 4, 16 and 64 to the CoS priority queues 0, 1, 2 and 3.
