Thank you for you answer, 1:10 is incresed but 1:20 is also increased and increase to the specific rate if I add 100kbps to every line. In my case, I would like to put all the extra to 1:10 only, is that means I have to give 1:11 ceil to 10kbps. If it is, is that means I don't need prio paramter? How prio parameter works? echo Clean all the tc setup ./tc qdisc del dev lo root ./tc qdisc add dev lo root handle 1: htb default 12 ./tc class add dev lo parent 1: classid 1:1 htb rate 100kbps ceil 100kbps ./tc class add dev lo parent 1:1 classid 1:2 htb rate 40kbps ceil 100kbps ./tc class add dev lo parent 1:2 classid 1:10 htb rate 30kbps ceil 100kbps prio 0 ./tc class add dev lo parent 1:2 classid 1:11 htb rate 10kbps ceil 100kbps <-- 10Kbps?? prio 1 ./tc class add dev lo parent 1:1 classid 1:12 htb rate 60kbps ceil 100kbps echo qdisc ./tc qdisc add dev lo parent 1:10 handle 20: pfifo limit 5 ./tc qdisc add dev lo parent 1:11 handle 30: pfifo limit 5 ./tc qdisc add dev lo parent 1:12 handle 40: sfq perturb 10 On Fri, 7 Jun 2002, Martin Devera wrote: > You either missed "ceil" parameter or it is missing on my page :) > Without ceil it is the same as rate thus all classes are bounded > in fact.
