You add a root cbq qdisc, that's fine, but > you need to add a class if you want to bound it to a rate. I see. That does explain a lot of things I haven't been able to pull together, actually. Thank you very much for pointing that out. > If you add a filter to a qdisc, it has to point to a class of that > qdisc. Not to an other class. That confuses me a bit. It does certainly make it work, and it does certainly make sense. However, in the advanced routing howto, section 9.5.2.1, it seems to very much implicate that you can create filters like that. Is that howto wrong or did I misinterpret something?

What's up with that?) > Try > tc -s -d filter show dev eth1 parent 2: Hehe... Don't I feel stupid now... Oh well, at least now I know (I thought all filters were in a per-interface namespace). Thank you for pointing that out. _______________________________________________ LARTC mailing list / LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
