The QoS > QoS Settings window displays the current QoS settings.

To configure the QoS settings, follow these steps.

STEP 1

Click

QoS > QoS Settings

.

STEP 2

Set the Queue Mode to Strict Priority or WRR.

•

Strict Priority

—Services the egress queues in sequential order,

transmitting all traffic in the higher priority queues before servicing lower
priority queues.

•

WRR

—Weighted Round-Robin shares bandwidth at the egress ports by

using scheduling weights 1, 2, 4, 8 for queues 1 through 4 respectively.

-

WRR Weight

—Displays the WRR weights to queues.
