So in your cas 100mbit. Second, you need to create a bounded class and attach it to the root qdis= c=20 with rate =3D bandwith. Attach both other class to this class in stead o= f the=20 root qdisc. And don't use the isolated parameter. It's not working. And take weight =3D rate /10. > Question 1: > > My intention is to apply a class.1 to TCP traffic class no.2 to UDP > traffic. Is that acheived?

I have some scripts on www.docum.org. First script is monitor.pl and it=20 gives a real time bandwith usage of the classes (it uses the byte counter= s of=20 iptables/ipchains and not the output of the tc command). I have a=20 web-interface example here : http://qos.dyndns.org:8080/cgi-bin/monitor.p= l I have also a version that can be used in a terminal. I also wrote a new script. It uses the=20 output of tc and rrd to create=20 some graphs (http://home.docum.org/stef.coene/qos/gui/rrd.html). Hope this helps Stef --=20 stef.coene@docum.org More QOS info : http://www.docum.org/ Title : "Using Linux as bandwidth manager"
