I don't know about it.why do that? How to it?

Below My filter and iptables rules

tc filter add dev eth1 parent 30: protocol ip prio 1  handle 8 fw classid  30:20
tc filter add dev eth1 parent 30: protocol ip prio 1  handle 9 fw classid  30:1000
tc filter add dev eth1 parent 30: protocol ip prio 1  handle 10 fw classid  30:2000

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.
