[c-nsp] CBWFQ/PQ Support on 6500/SUP720-3BXL

[Zahid Hassan]

Thanks Douglas, I am still tyring to the find out if there is a way to  do this with wrr-queues.

The bit that I am not sure about is how to match on EXP bits within wrr-queues.


Does anyone know if this is at all possible ?


Regards,


Zahid
