Configuring the Switch
3-102
CLI – The following sets the queue mode to strict priority service mode.
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).

* 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.
