You separate all traffic for to groups

1. udp range 1000 and 2000
2. and rest traffic...

first - you are marking and policing
second - queueing (priority-group 2)

  I understand that the below config may not work....as the exceed action is
"Transmit".So does it ever go to the next statement. So anything above 6 Mbps
wont try to match the next rate-limit statement.

> rate-limit output access-group 110 6000000 25000 37500 conform-action
     set-dscp-transmit 46 exceed-action transmit
> rate-limit output 2000000 50000 62500 conform-action transmit
exceed-action
>drop

  Anyone else ? care to add.

  Good Luck,
  Kasturi.
