Hi
I have now my outgoing traffic shaped whith root
qdisc htb (where i configure basic rate) and tc
prio (as a leaf with 4 classes) where i can set
priority of different kinds of traffic. It works
but htb is work-conserving so packets are only
delayed (when the rate is exceeded), while i want them dropped. In the case when rate is exceeded i want to drop packets with priority set to 4, then if traffic still too high to drop packets with priority set to 3 and so on. So i need tc-prio under tbf.
But tbf is classless. Can i do what i want in some
other way? Or maybe i'm misunderstanding something
- when htb start to drop packets?

Maybe you could use htb + prio and add 4 p/b fifos to the prio classes and set low lengths with the limit parameter of the fifos.
