And remove all isolated parameters. They are not working. In fact, if you add a isolated parameter to class 1:10 and 1:20 then these class will get more bandwidth then the parent allows even if the parent is bounded. I think it's a bug in cbq (more info on http://www.docum.org/stef.coene/qos/tests/cbq/classes.html). tc qdisc add dev eth0 root handle 1: cbq bandwidth 10Mbit avpkt 1000 cell 8 tc class add dev eth0 parent 1: classid 1:1 cbq bandwidth 10Mbit rate 256 Kbit weight 2.56 Kbit prio 1 allot 1514 cell 8 maxburst 20 avpkt 1000 bounded tc class add dev eth0 parent 1:1 classid 1:10 cbq bandwidth 10Mbit rate 32 Kbit weight 3.2 Kbit prio 1 allot 1514 cell 8 maxburst 18 avpkt 100 tc class add dev eth0 parent 1:1 classid 1:20 cbq bandwidth 10Mbit rate 224 Kbit weight 2.24 Kbit prio 2 allot 1514 cell 8 maxburst 2 avpkt 1500 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/
