Is there a recommended practice for determining the best QoS burst setting when policing on an (ethernet) interface over a WAN circuit...so you get the best throughput as as close to the cir as possible?
Say you have a 20MB wan circuit and want to police a certain type of traffic to say 5MB we can say this is web traffic. What would be a way to determine the best burst speed for optimal throughput for the policed traffic allowing up to the cir speed.
In your case, you are just using the defaults, so that should work fine.
Question is, why are you shaping and policing?
If you just apply the service-policy police to the interface directly, traffic won't exceed the bandwidth anyway.
