I successfully used a bounded cbq to cut down outgoing bandwidth to certain addresses on eth0: # tc qdisc add dev eth0 root handle 10: cbq bandwidth 100Mbit avpkt 1000 # tc class add dev eth0 parent 10:0 classid 10:1 cvq bandiwdth 100Mbit rate 100Mbit allot 1514 weight 1Mbit prio 8 maxburst 20 avpkt 1000 # tc class add dev eth0 parent 10:1 classid 10:100 cbq bandwidth 100Mbit rate 1Mbit allot 1514 weight 10Kbit prio 1 maxburst 20 avpkt 1000 bounded # tc qdisc add dev eth0 parent 10:100 sfq quantum 1514b perturb 15 # tc filter add dev eth0 parent 10:0 protocol ip prio 100 u32 match ip dst 192.168.1.0/24 flowid 10:100 I basically copied this straight out of a howto - now I can't figure out how to remove the limitations (without rebooting that is). I was expecting something like: # tc filter del 10:100 or possibly # tc class del 10:100 but clearly I don't really understand what's going on here... any pointers? Thanks, Ben
