Hi Guys,
 
In the rate limit statement or question if only rate is given(assue 20mbps), how do we arrive at values for extended and normal burst sizes. I know this has been discussed earlier but any help is appreciated.
eg:
rate-limit output access-group 101 20000000 24000 32000 conform-action set-prec-
transmit 5 exceed-action set-prec-transmit 0
 
ps:
20000000- in bits per second
24000----bytes
32000----bytes
How do they arrive at 24000 and 32000 values.
 
thanks
