RE: 3 colour policing single rate and three colour policing

If you all you have to do is drop when exceeding and nothing else, just configure a 2-color 1 rate. Your customer is either adhering to the policy or he's not, if he's not he's dropped.

If you want to allow excess sometimes, then you need to figure out what you're willing to accept and what to do with the excess. I would re-read that first link, it explains the concepts well.
