Hi Bill
if you have enough time and equipment, try it...
it's pretty interesting actually.
you only need two catalyst, and three PCs.
(one of the PC run traffic generator to flood the trunk, you can use Brick, TFGen or anything else).
usually by using priority-queue out, queue-id 4 will be expedited.
and when congestion happen, anything else beside that queue-id 4 will be dropped.
I think the docCD you are reading is not correct.
you will not need that priority-queue out if you already define the wrr-queue bandwidth command.
Rgds,
Thomwin

Here is the requirement :
Cos-3 must be sent of everything else and match the following cos values to
according bandwidth.
Cos 3 = 25%
CoS 6,7 = 20%
CoS 0,1,2 = 30%
CoS 4,5 = 25%
Here is the solution:
wrr-queue bandwidth 4 6 5 5
wrr-queue cos-map 1 6 7
wrr-queue cos-map 2 0 1 2
wrr-queue cos-map 3 4 5
wrr-queue cos-map 4 3
priority-queue out
I don't understand the values in the wrr-queue bandwidth command and trying
to look at the doc cd is just confusing me more. Can anyone point me to a
better explanation of how the values were estimated?
Thanks,
Bill
