This question has been asked many times around here :))
I remember i answered it back in April:
----First is *single-rate* three-color policer (RFC 2697).
http://www.cisco.com/univercd/cc/td/doc/product/software/ios124/124cg/hqos_c/ part20/ch05/hpoli.htm
Second is *two-rate* three-color policer (RFC 2698).
http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122t /122t4/ft2rtplc.htm
----
In real life, when you let PIR=CIR, Bc=Be with two-rate policer you get the same behavior as with single-rate.
