just remember the different calculation in
traffic shaping and policing
all calculations stem from these two
in you example it really does not limit the speed to 15meg
the one below will allow only 15meg
rate-limit output 15000000 2812500 2812500 conform-action transmit
exceed-action drop
with yours you are giving a little more bandwith
when bc=be there is no bursting ...you are allowing to burst
