I believe in the current scheme, 1:170 is child from 1:1 and 1:30 a child from 1:170. I think you want both 1:170 as 1:30 to be children from 1:1. > tc qdisc add dev eth0 parent 1:30 tbf rate 30Kbit buffer 10Kb/8 limit > 15Kb mtu 1500 > tc filter add dev eth0 parent 1:0 protocol ip prio 100 u32 match ip dst > 10.10.20.95 flowid 1:30 > > tc class add dev eth1 parent 1:171 classid 1:31 cbq bandwidth 200Kbit > rate 30Kbit weight 3Kbit prio 6 allot 1514 cell 8 maxburst 20 avpkt 1000 > tc qdisc add dev eth1 parent 1:31 tbf rate 30Kbit buffer 10Kb/8 limit > 15Kb mtu 1500 > tc filter add dev eth1 parent 1:0 protocol ip prio 100 u32 match ip dst > 10.10.30.2 flowid 1:31
