Creating egress queue weights
The Passport 1600 Series switch contains 4 hardware priority queues. Three of these queues use DWRR, while the fourth uses SP. Incoming packets are mapped to one of these four queues.
This example explains how to configure egress queue weights. Specifically, it involves prioritizing traffic on egress port 39.
The table and figure that follows illustrates the configuration involved in prioritizing traffic on port 39.
