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
2-89, 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.
