The QoS Exam Certification Guide doesn't mention the 'police rate' command at all and I've been trying to figure out if there is any difference between this and the 'police cir' command (besides the fact that 'police rate' allows you to configure the rate as bps or packets per second, and 'police cir' only allows bps). I found this on Cisco's site which sounds like 'police rate' is meant to be used for control plane policing:

and this on Internetwork Expert's forums which says the same thing (read the last post by Petr Lapukhov):

However I've found that both 'police rate' and 'police cir' are able to be configured in a policy and applied on an interface. Wouldn't the result of using either of the following 2 commands and applying the policy to an interface be the same?
police cir 64000 bc 8000 conform-action transmit exceed-action drop
police rate 64000 burst 8000 conform-action transmit exceed-action drop
Is there any reason not to use 'police rate' on an interface, or is this just two different ways of doing the same thing?
