If you check the archives there's a discussion going on right now about this... You can use a classful qdisc such as HTB, create a leaf for each IP address, then filter into that leaf using the U32 filters. Something like this (untested - I've only copied from the list archives): tc qdisc add dev eth0 root handle 1: htb r2q 1 tc class add dev eth0 parent 1:0 classid 1:1 htb \ rate 3000kbit ceil 3000kbit tc class add dev eth0 parent 1:1 classid 1:100 htb \ rate 1500kbit ceil 1500kbit prio 3 tc filter add dev eth0 parent 1: protocol ip u32 \ match ip dst 172.16.254.1/32 classid 1:100 tc qdisc add dev eth0 parent 1:100 handle 100: sfq perturb 2 tc class add dev eth0 parent 1:1 classid 1:101 htb \ rate 1500kbit ceil 1500kbit prio 3 tc filter add dev eth0 parent 1: protocol ip u32 \ match ip dst 172.16.254.2/32 classid 1:101 tc qdisc add dev eth0 parent 1:101 handle 101: sfq perturb 2 ... You'll need a leaf class for each IP address, and all the leaf classes should add up to the parent. By the way - please start a new email when starting a new thread. If you reply to a previous email and change the subject then your email will still appear in the original thread in the message archives.
