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 2-53, 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 spe-
cific 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.”
