Ingress seems to be a topic that is discussed often on LARTC, and I believe your options are to either use an ingress policer or the IMQ target. The former you can do directly with tcng, the latter I believe you cannot. > That is, each client inside the LAN should get garrantied > - PER_CLIENT_DOWN=256kbit/s > - and PER_CLIENT_UP=42kbit/s > Each unused bandwith may be shared between them. > > The LAN clients have IP pool: > 192.168.2.2-192.168.2.4, and > 192.168.2.6-192.168.2.8 > > But how exactly do I now express my wish in TCNG syntax? > > Some kind of pseudo code like below... > <snip> > The "device" object is meant to represent the device's configuration > specific data.

You'd probably use HTB for egress. If you decide to use IMQ you might use it in both directions. > Sorry, this is *my* brain-dead-pseudo-code to explain, what I want, with a > syntax associated to the tcc(tcng) examples I have found on the net. > > Could someone *now* show me, how my goal should look in tcng syntax? I don't think you can use IMQ from within tcng, so you may not be able to do ingress and egress with a single tool. > Many thanks, > Christian Parpart. -- Jason Boxman Perl Programmer / *NIX Systems Administrator Shimberg Center for Affordable Housing | University of Florida http://edseek.com/ - Linux and FOSS stuff _______________________________________________ LARTC mailing list / LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
