Question on 65k QOS configuration

Hi,

Currently our company has 65k switch where qos is enabled. it has the following configurations for video traffic and network protocols traffic with the following threshold values

wrr-queue cos-map 2 2 4

wrr-queue cos-map 3 2 3

wrr-queue cos-map 3 3 6 7

wrr-queue queue-limit 40 30 15

wrr-queue random-detect min-threshold 1 40 60 80 80 80 80 80 80

wrr-queue random-detect max-threshold 1 70 80 100 100 100 100 100 100

no wrr-queue random-detect 2

no wrr-queue random-detect 3

wrr-queue threshold 2 60 80 100 100 100 100 100 100

wrr-queue threshold 3 60 80 100 100 100 100 100 100

what is the advantage of changin that to different queue/threshold

wrr-queue cos-map 3 5 4

wrr-queue cos-map 3 2 3

wrr-queue cos-map 3 3 6

wrr-queue cos-map 3 4 7

wrr-queue random-detect min-threshold 2 80 80 100 100 100 100 100 100

wrr-queue random-detect max-threshold 2 100 100 100 100 100 100 100 100

wrr-queue random-detect min-threshold 3 80 70 80 90 100 100 100 100

wrr-queue random-detect max-threshold 3 100 80 90 100 100 100 100 100

Re: Question on 65k QOS configuration

naveen a 6500 can have qos based on the module. so modules have priority q + normal transmit.

some have only normal queues without any priority.

I can see that the cos map being changed from using queue2 and 3 to just queue 3. so any  frames with cos 3 4 6 7 will be serviced in queue 3 with various thresholds. threshold indicated in random detect have two values

minimum threshold define at what % of the queue limit should wred kick in to start weighted random discarding packets beyond this % threshold limit

max is the maximum threshold in % of queue capacity that will start the all packet discard beyond this point scenario.
