Well yes, when you are basically fixing the bandwidth for each class (class-map)
What I was trying to say is that it's not possible to run wrr or wred
then the actual bandwidth behind the 10G is e.g. 3G.
The purpose would be to allow priority traffic have priority and then
let best effort fill the rest of the pipe
