I don't know about it and why do that ? how to do it?

If I want to fixate every class bandwidth. not lended and not borrow .How to do it.
cburst play tricks??
On www.docum.org's FAQ have :
The same story goes for ceil and cburst, you don't want the class to send more packets then it's ceil allows. So removing the cburst is a good choice for that case.
