[LARTC] Ok, a simple one then..

[Paul Wisén]

I use CBQ with sfq and tbf.

I want to have one "mother" class that gets all traffic in our network.
So I define cbq-0010.mother
with RULE=:,192.0.0.0/24

and I want a subclass to get all the data from a specific ip.
So I define a subclass

cbq-0065.8011_in
with
PARENT:0010
and RULE\x192.0.0.10

It doesnt matter how I do it. I've tested chainging the names, parent
numbers and so on.
The mother class always gets all the data.. Why ?
Ofcourse the first rule says that it should but, what if there'se some other
class that also would have triggerd on the packet ? How do I control witch
class gets what packet, if therese multiple true rules.. ??

please, anyone ??

/ Paul

Paul, I've seen your 'small ISP' posting but have not yet gotten round to
thinking it over.

You are using cbq.init.

# LEAF=none|tbf                                 optional, default "tbf"
#
#       Instructs the script to attach leaf queueing discipline to CBQ class.
#       By default, TBF is used. This parameter is useful for parent classes
#       where you probably want to specify LEAF=none. In future it might be
#       possible to use SFQ or CBQ (or other) as leaf qdisc.

You might want to specify that. But it might be that you are exceeding the
limits of cbq.init.

What you basically need is to get your second class to have a filter that
comes *first*, before the filter directing all everything to cbq-0010!

You can also set cbq.init to write out what it will do. Then you can change
the priority of filters, making sure that the more specific rules get tested
first.
