Policing is very limited. It operates all-or-nothing on all the packets
arriving at an interface. There is no opportunity to parse the packet
and distinguish between VLANs or other fields.
You can do a form of QoS with meters, perhaps satisfying the rates that
you mention, but it operates on the packets transmitted to an interface,
not on the packets received on one.
