Hello...
Im trying to setup HTB to allow me to shape traffic from two upstreams
that meets on single lan0 interface. I prefer to use HTB qdisc
within HTB root qdisc for cleaner rules design.
Seems that it doesnt work at all. tc -s class show doesnt
show any traffic on other classes attached to HTB qdisc.
Linux 2.6.20.7
iproute-2.6.20-070313
Weird thing is that tc -s class show that 1: and 2: are both root
class, where it is not true since they both have parent qdisc 1: or 2:
and those qdisc arent root, they have parent class 10:11 or 10:12 (what
tc -s qdisc show says).
Is HTB qdisc within HTB qdisc is valid on newer kernels? If yes, what is
wrong in this setup?
This setup works fine when I use one HTB qdisc and many classes within
classes.
How it looks like:
