Hello, I use Linux VLAN with a Cisco Catalyst switch. The VLANs are working now properly. I have to set up traffic-shaping on interfaces and I have some questinos: 1. which is better: using the physical interface (e.g. eth0) or the VLAN interfaces (vlan000x)? 2. if I use the physical interface what should I take care about? - u32? 3. if I''m right traffic sharing is possible only a phys. interface, virtual interfaces have separated quues? 4. can I somehow configure the max. bandwidth that the user can use for communication? I know up/downstream is configurable but how can I manage these 2 queues? example: user has 64k, but he can download with 64k and the same time upload with 64k, so it is 128k on my lines. I would like to allow only 64k... Sorry for Q4, it is not about VLANs... Any other idea how should I solve this problem? Does anybody have any experience with this? Please write me anny comments/notes. Kind regards, Thomas _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
Hello, thank you for your help. I''m looking for IMQ. It looks pretty cool :) Is the IMQ code in the kernel (I use kernel 2.4.20)? I found only: Ingress Qdisc. Is it the Intermediate queueing device? I have iptables v1.2.6a (from RedHat 8.0). How can I combine IMQ and priority queueing? I MUST set up prioritization for RTP, so it is very important to prefer RTP packet. If I''m right IMQ can''t do PRIO queueing. Thank, Thomas On Fri, 29 Nov 2002, S Mohan wrote:> Traffic shaping can be done on physical or virtual devices.

For RTP, you need a combination of a low delay and stable bandwidth. You can do this with htb or cbq. And you don''t have to use imq. I think it can be done on 1 interface.> Thank, > Thomas > > On Fri, 29 Nov 2002, S Mohan wrote: > > Traffic shaping can be done on physical or virtual devices.

Good doc available at > > www.docum.org thanks to Stef Coene.Mhh. Imq has 1 queue, not incoming and outgoing queues. But you can redirect packets to it from INPUT and OUTPUT. So from in and outgoin traffic. So you can use incoing and outgoin control on the same device.
