The link itself is a 100%-CIR SDSL (for LANof 300+ machines). I've set up ceil(up and down) to ~95% of real bandwidth. It seems that classes exceed maximum rates (ceils) defined for them. For example : p2p class has ceil of 2.5 mbits When p2p traffic is not allowed to pass through bandwidth usage varies around 30%. Afrer allowing p2p to pass bandwidth usage quickly rises to nearly 100%. Is it possible to somehow isolate a class (as in cbq?) ?. In the archives I've found something like this (let's say): '[...] rate 2500kbit ceil 2500kbit'. This should produce something like isolated class , but for me it simply doesn't work. I'd be very grateful for any suggestions / ideas ...
