Guarantee bandwidth for a specific host

Hy!
There is a customer which have 30/30Mb internet connection. Now there aren’t any queue rule. I would like to set the guarantee bandwidth 8/8Mb for a specific host? I can create a simple queueu and specify the target host on the Target: field, but where can I set the 8/8Mb value to guarantee the minimum bandwidth? Limit At filed on the Advanced field?


I created a simple queue:
Target: specific host IP
Max limit: Upload: 30M , Download: 30M
Limit At: Upload: 8M, Download: 8M


Is it correct? Does it need the mangle rule?

Thanks.

Anyone?
