Thanks Andrey, you mentioned ... "In fact, I found in some cases QoS hurts more than it helps, because you are limiting the amount of bandwidth available to high priority packets (either priority, policy or shape) and you will have a chance for tail drops or WRED even on a non congested link."
Question - what if you don't limit the amount of bandwidth available to high pri traffic, in other words, what if, on a 1 gig link, you say 1 gbps for the priority queue and 100% available to everything else, and then if there is hi-pri traffic, it gets what it needs, but when there isn't hi-pri traffic taking up 1 gbps, then everything else can use up to 100% minus what hi-pri traffic needs. ? eng-lab-3600-1#sh run policy-map qos-test Building configuration...
