I use this configuration in kernel 2.2.16 : ./tc qdisc add dev eth0 root handle 1: cbq bandwidth 10Mbit cell 8 avpkt 1000 mpu 64 ./tc class add dev eth0 parent 1:0 classid 1:1 cbq bandwidth 10Mbit rate 10Mbit allot 1514 weight 1Mbit prio 7 maxburst 20 avpkt 1000 bounded isolated ./tc class add dev eth0 parent 1:1 classid 1:100 cbq bandwidth 10Mbit rate 800Kbit allot 1514 weight 80Kbit prio 5 maxburst 21 avpkt 1000 bounded ./tc qdisc add dev eth0 parent 1:100 tbf rate 800Kbit burst 20Kbit mtu 1514 peakrate 820Kbit latency 500ms ./tc filter add dev eth0 parent 1:0 protocol ip prio 5 u32 match ip src 192.168.127.1/32 flowid 1:100 My problem is that this configuration works well in kernel 2.2.16.
