You create bounded cbq classes and you add a tbf qdisc that bounds the traffic in these classes again. So you don't need the tbf qdisc. I'm not sure it will change a lot, but you can try to replace the tbf qdisc with a prio or sfq qdisc. > Here's my tc config rules, minus the long list of ports in the class: > > tc qdisc del dev eth0 root [eth0 is the Internet facing interface] > tc qdisc add dev eth0 root handle 1 cbq bandwidth 10Mbit avpkt 1000 cell 8 > tc class change dev eth0 root cbq weight 1Mbit allot 1514 > > tc qdisc del dev eth1 root [eth1 is the intranet facing interface] > tc qdisc add dev eth1 root handle 1 cbq bandwidth 10Mbit avpkt 1000 cell 8 > tc class change dev eth1 root cbq weight 1Mbit allot 1514 > > tc class add dev eth1 parent 1: classid 1:50 cbq bandwidth 10Mbit rate > 35Kbit weight 3Kbit prio 5 allot 1514 cell 8 maxburst 20 avpkt 1000 bounded > tc qdisc add dev eth1 parent 1:50 handle 50 tbf rate 35Kbit buffer > 10Kb/8 limit 15Kb mtu 1500 > tc filter add dev eth1 parent 1:0 protocol ip prio 100 u32 match ip > sport 1755 0xffff match ip dst 0/0 classid 1:50 > tc filter add [etc....] Stef -- stef.coene@docum.org "Using Linux as bandwidth manager" http://www.docum.org/ #lartc @ irc.oftc.net _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
