[solved] Indivdual bandwidth limits using TC.

Hello, I'm looking to give each IP in a subnet it's own max bandwidth limit. I've looked at this:

tc qdisc add dev $DEV root handle 1: cbq avpkt 1000 bandwidth 10mbit

      tc class add dev $DEV parent 1: classid 1:1 cbq rate 512kbit \
      allot 1500 prio 5 bounded isolated

      tc filter add dev $DEV parent 1: protocol ip prio 16 u32 \
      match ip dst 10.8.0.1/24 flowid 1:1

The problem: Instead of each IP in the subnet getting a max of 512, 512 is split between everyone in the subnet.
Does anyone know a way to accomplish my objective?

You're sharing the 512 between the class between all the IP addresses. You'll need to create a class for each IP that you want to dedicate it's own bandwidth to.

(Yes, tc is far from elegant)

Thank you, that works, at least using 10.8.0.5 and 18.8.0.6 as a test case. Maybe I can script it.
