Yes. I have 1:99 class. I didn't write all script.

It's mistake. Should be 256Kbit

Thanks.
Second question.
I play with htb.init-v0.8.4 from sf.net and QOS configurator from
docum.org.
I attached my htb script.
Then I get statistics:

Opps. All overlimits in classes is zero!
That I wrote in my first message.
It's strange for me.
I want to know what protocol had overlimit.
