Hi Ramesh,

If you get your traffic into queues via a classifier or some other
means, you should be able to use the "exact" keyword on that PIC on
each of the schedulers attached to the queues. This will get you
shaping per queue with the caveat being you only have 4 queues for the
physical port.

If you have a config to share with a "show interface extensive" for
the egress interface, I'm sure we can see if there are any issues.

Pete
