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

[Todd, Douglas M.]

Zahid:

We were looking at the same senerio and found that we must use a SIP type card
to do any traffic shaping.  The 6500 does not have this type of feature.
SIP-200/400 for either DS1/100FD/1G type of connections.

Hope this helps.

Douglas

For MPLS packets, the EXP value is mapped into an internal DSCP so that the
PFC3BXL or PFC3B can apply non-MPLS QoS marking and policing.
