hi! I'm trying to control down- and upstream with a 2.4.3 kernel, iptables and tc. I managed to limit the upstream and it works perfect, but somehow my downstream traffic seems not to be affected from traffic controlling. I'm not sure if I missunderstood something or perhaps only mixed up some parameters - I tried several configurations, but it's always the same: the traffic is filtered to the correct class, but there's no limitation. The "strongest" connection can always allocate allmost all downstream traffic. So here's the setup - perhaps someone can give me a hint? # DDEV="dev eth0" # DBAND="bandwidth 768Kbit" # DOPT="maxburst 20 avpkt 1000" eth0 is the device to the lan, the average pakte size should be arround 1000 (I got this from some netfilter byte counters) - but I'm not sure about maxburst - I just took ist from the HOWTO - what's that for? # $TC qdisc add $DDEV root handle 1: cbq bandwidth 100Mbit avpkt 1000 mpu 64 # $TC class add $DDEV parent 1:0 classid 1:1 cbq bandwidth 100Mbit rate 100Mbit allot 1492 weight 10Mbit prio 8 $DOPT # $TC class add $DDEV parent 1:1 classid 1:2 cbq bandwidth 100Mbit rate 768Kbit allot 1492 weight 77Kbit prio 6 $DOPT bounded # $TC class add $DDEV parent 1:2 classid 1:3 cbq $DBAND rate 688Kbit allot 1492 weight 70Kbit prio 1 $DOPT # $TC class add $DDEV parent 1:3 classid 1:100 cbq $DBAND rate 384Kbit allot 1492 weight 38Kbit prio 4 $DOPT # $TC class add $DDEV parent 1:3 classid 1:200 cbq $DBAND rate 120Kbit allot 1492 weight 12Kbit prio 2 $DOPT # $TC class add $DDEV parent 1:3 classid 1:300 cbq $DBAND rate 120Kbit allot 1492 weight 12Kbit prio 3 $DOPT # $TC class add $DDEV parent 1:3 classid 1:400 cbq $DBAND rate 64Kbit allot 1492 weight 12Kbit prio 5 $DOPT # $TC qdisc add $DDEV parent 1:100 prio # the same with [1:200, 1:300 and 1:400] Now `tc -s qdisc` shows that no pakets have been dropped, there's no overlimit, but for example the 1:300-class got 60M while 1:200 and 1:100 only got 10M traffic per class. My first thought was, that if I use the full bandwidth there won't be anything to limit, because the classes are always borrowing bandwidth to and from each other - so I changed the rate of class 1:3 to 688Kbit to have 80Kbit "to share" but that also had no effect. Now I've no more ideas what to change - any ideas? thanks a lot for your time :) Sebastian -- Sebastian 'spax' Pape | Your mouse has moved.
