SMC Networks SMC6752AL2 manual 173, Setting the Service Weight for Traffic Classes

CLASS OF SERVICE CONFIGURATION

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 3-169,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 Table15 – Displays a list of weights for each traffic class (i.e., queue).

•Weight Value – Set a new weight for the selected traffic class. However, note that Queue 0 is fixed at a weight of 1, and cannot be configured. (Range: 1-31)

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