Cisco 3750 QOS using SRR

Hi all

I am studying QOS mechanisms on Cisco 3750.

I have a question about SRR (Shaped Round Robin).

Does somebody knows how the router classify these mechanisms :

I mean if I have a config like that :

srr-queue shape 10 0 0 0

srr-queue share 10 25 35 30

priority-queue out

I have 3 flow (data, voice, scavenger)

I have put voice un the first queue using mls qos maps commands

What I have understood is that shape is stronger that share, so voice will get 10% of the bandwidth

The srr-queue share 10 25 35 30 wion't consider the first value anymore.

But what will be the effect of priority-queue command ?

It seems during tests that this command "dominate" both srr-queue shape and share,

I mean that it will be the first to be considered.

If I put voice in queue 1 and activate priority queuing , voice take all the bandwidth whatever is

configured using srr-qeueue, can somebody confirm ?

Thanks for help.

Regards.
