Venkat,

I think you have it wrong. The Blade WS X6724-SFP Support 1P-3Q-8T

That is one priority Queue 3 regular queues and 8 tail drops. An
example config for this device is as follows:

 wrr-queue bandwidth 5 25 70
 wrr-queue queue-limit 5 25 40
 wrr-queue random-detect min-threshold 1 70 100 100 100 100 100 100 100
 wrr-queue random-detect min-threshold 3 50 60 70 80 90 100 100 100
 wrr-queue random-detect max-threshold 1 80 100 100 100 100 100 100 100
 wrr-queue random-detect max-threshold 2 80 100 100 100 100 100 100 100
 wrr-queue random-detect max-threshold 3 60 70 80 90 100 100 100 100
 wrr-queue cos-map 1 1 1
 wrr-queue cos-map 2 1 0
 wrr-queue cos-map 3 1 4
 wrr-queue cos-map 3 2 2
 wrr-queue cos-map 3 3 3
 wrr-queue cos-map 3 4 6
 wrr-queue cos-map 3 5 7
 priority-queue cos-map 1 5

In fact the show output says the same.. So I am puzzled if my
understanding of WRR is wrong.!

    Queueing Mode In Rx direction: mode-cos

    Receive queues [type = 1q8t]:

    Queue Id Scheduling Num of thresholds

       01 WRR 08
