the LAN cards on a 6500 only support policing (you need the extra
buffers on OSM/Flexwan/SIP to do shaping). And you can't apply this
inbound on the 7200 as inbound shaping is not supported anywhere (?) at
the moment, so you need to turn this into a policer.  

But I'm not sure what you want to achieve. Limit the overall BW to
6Mbit, and within this 6Mbit do preferred treatment for some traffic
type? In the original post, you mentioned 6Mbit + some addlt. BW for
extra traffic/IP.. can you pls clarify?
