Actually Sila I think there is a big difference, but don't have a lot of
time this AM...heading to spend my Saturday in a fun NMC lab the rest of
the day..

But if I remember right when you have multiple priority queues set up in
MQC it becomes a like fifo round robin setup where as in priority
queuing if there is data in the high queue it will always get serviced
first.

Subject: QoS - legacy priority convert to MQC

Hi

I'm practicing QoS. I've some questions.

Are the two methods the same? If not specified, I can
assign any value to my priority right? BTW, if my
total value exceed 75%, I should use
'max-reserved-bandwidth xx' under the interface. What
if the value is less than 75%?

TIA
Sila
