"For example, calculate the minimum burst value in order to sustain a rate of
1 Mbps.
The rate is defined as 1000 Kbps, so the minimum burst needed is the sum of
this equation:
1000 (Kbps) / 8000 (1/sec) =125 (bits)
The minimum supported burst size is 8000 bytes,which is more than the minimum
burst calculated.
Note: Due to hardware policing granularity, the exact rate and burst is
rounded to the nearest supported value."

Trying to setup inbound policing on 3550 to limit ICMP traffic to a max of
256Kbps. Is their a way to calculate the burst bytes given the average or max
rate ? Anyone have a good link to explain values ?
<police rate-bps burst-byte>
class-map match-all map1
match access-group name ICMP

policy-map pmap1
class map1
police 256000 ?? exceed-action drop
ip access-list extended ICMP
permit ICMP any any
Thanks
