Hi Fabio, You should do something like this: tc qdisc add dev eth0 root handle 1: prio bands 3 tc qdisc add dev eth0 parent 1:1 handle 2 sfq perturb 10 tc qdisc add dev eth0 parent 1:2 handle 3 sfq perturb 10 tc qdisc add dev eth0 parent 1:3 handle 4 sfq perturb 10 tc filter add dev eth0 protocol ip parent 1: prio 1 <your criteria_high> flowid 1:1 tc filter add dev eth0 protocol ip parent 1: prio 2 <your criteria_middle> flowid 1:2 tc filter add dev eth0 protocol ip parent 1: prio 3 <your criteria_low> flowid 1:3 That works in my system. 2009/5/20, Fabio Marcone <fabio.marcone@xxxxxxx>: > Hi all, > I'm studying traffic shaping and I need some informations. > I studied HTB and I had no problem to limit bandwidth (with and without > borrowing).
