I am using tbf to do bandwidth limitation. i found that when i start passing traffic there is a burst and then the rate goes down to what is configured. is this a known issue or do i need to change some parameters? 
 
thanks.

The behaviour you have described is exactly the theoretical goal of 
a token bucket filter, and also the practical behaviour of the TBF 
queueing discipline.  In other words, congratulations, you are 
using a TBF!

You probably wish to tweak parameters.
