It's hard to tell because these two things (cbq and tbf) use different methods, which could interact strange way (and are not expected to work together). I think you should test them alone first (especially tbf), and send here the tc comannd plus "tc -s qdisc show dev eth0" and "tc -s class show dev eth0" output while traffic is run. You could also add this "ethtool -k eth0" and "ifconfig eth0". Jarek P. > >> > >> Hmm...
