Re: Question about QoS on C3750

I think you should be just fine with the default queueing mechanisms if you
put your video traffic in the priority queue. The default buffers give you
25% of the interface buffer in the priority queue and 400% maximum
(borrowing from the common pool). 25% of your Gig interface gives you
250Mb/s

To see what you have allocated check out "show mls qos queue-set" and "sh
mls qos interface <x/y> queueing"
