Humm are you sure. The topic of the question was "QoS Limiting in 10Gb"
I know that you limit the traffic ignoring QoS (DSCP values) e.g.

policy-map 3GbE
  class class-default
   police cir 3000000000 bc 562500000 conform-action transmit
exceed-action drop     violate-action drop

but how can you do it with a Diffserv policy, e.g. wred/wrr?
