IOS XE Policy Map Policing

Phil Clemens · ‎07-26-2017

I am trying to perfect our policy maps, which restrict our customer bandwidth to their subscribed rate.

What I am missing is the relationships between cir/bc/be and the exceed action.

Given the following config

police cir 50000000 9375000 18750000 conform-action transmit exceed-action drop

What is being exceeded and dropped, the bc or the be? Should my exceed action be transmit, and then the violate action be to drop?

Should the pir come into play?

I've found a few documents and threads out there, but nothing that really defines these relationships.

Reading more into this, I am getting the bucket concept. However, what I'm not sure about is when the buckets come into play. Is it always, or only after the cir is exceeded? If the buckets are always part of the process, then why define a cir? Why not just define a bucket size that is your desired cir/8?
