Questions on policy-maps

I'm looking to configure policy-maps to implement bandwidth levels and I had a question:

Using police command, what does the burst subcommand actually affect? Is this the amount of bandwidth that can exceed the average rate?

Hello Joe,

the best thing is to read the command reference

http://www.cisco.com/en/US/docs/ios/qos/command/reference/qos_n1.html#wp1046487

the burst can be seen as an additional buffer expressed in bytes to handle some packets in excess to rate.

Hope to help

Re: Questions on policy-maps

It indirectly determines what time period is being used to measure the transmission rate. Realize a policer (or shaper) allows traffic at full link/interface bandwidth rate, the CIR (and/or PIR) is based on an amount of bits transfered during some time period.
