In order to set up policing, you must define the QoS policy maps and apply them to ports. This is otherwise known as port-based QoS.

Refer to this document for more information on policing:

looking forward for the method on which bandwidth stated in the policing command is computated.

e.g after enable qos on box & creating proper class-map & policing on an interfacef0/1 for 20mb. If a send 64 byte ethernet frame ( 46 byte-data) what would be the rate effectively one would get.
