Hello, I''ve got somes questions about Bridge and QOS ... I''ve got a serveur with 2 interfaces eth0,eth1 inside br0 bridge ... nothing of special ...

Hello I have few questions regarding tc functionality (qdiscs, classes, etc.) when vlans are in use. For example, consider interface eth0, for which I create and extra vlan with vconfig, let''s say eth0.11. Then using tc I can add usual things - qdiscs, filters, ... - to both eth0 and eth0.11. The questions are: - on which interface - virtual or real, should I actually use tc ? Or

Hi folks. For quite a while, I tried to use linux (cbq and htb) to control bandwidth in order to replace a cisco equipment used to play this role on our network. After trying here and there, with a bunch of different distros, different versions, different compilations, ... the closest I could get was as follows: (using htb.init and cbq.init) Desired BW ==> Achieved BW 128k ==> 404.78
