Subject: help with cbq scheduling

Im having a small problem with scheduling which I was hoping i could get 
some help with.

Im trying to setup a semi complex set of pools for a project im working on. 
Im using cbqinit however I don't understand how or if parents work the way 
im expecting them too.

What I want to do is have 3 main pools ( on a gig link)

A 400mbits max
B 400mbits max
c 300mbits max

however under "c" I want some sub pools

c.1 150mbit max
c.2 200mbit max
c.3 250mbit max

However I don't want the sub groups of "c" to ever use more then the 
300mbits it is allowed.

Ive tried using parent in cbqinit however it is ignoring the "c" pool rule 
and just using however much the sub pools c1, c2, c3 want to use. So it is 
using a max of 600mbits not 300mbits.


my cbqinit files are

cbq-1280.A

Any help would be great. Im stumped, or just mis-interpreting things.
