I'm using tc to control traffic to some networks. In this case, I have 2
different classes going through eth2 (in a rh 7.2box).
The point is that I want that all traffic to the classes 200.39.174.0/24
and 200.39.187.0/24(the sum between them) be limited to 256.
How can I tell "tc" to limit 2 classes to the same flowid?
Right now I'm using:
tc filter add dev eth0 parent 10:0 protocol ip prio 100 u32 match ip dst
200.39.174.0/24 flowid 10:256
tc filter add dev eth0 parent 10:0 protocol ip prio 100 u32 match ip dst
200.39.187.0/24 flowid 10:256
But these leaves 256 to each network, and I want 256 to the sum of them.
Any idea?
Omar

I asume you want each network to use 50% of the bandwith (but they may borrow
from each other)? The only thing you have to do is to create 2 new classes
with parent 10:256 , rate = 128 and with no bounded parameter. Point the 2
filters to the 2 new classes and you'r done.
And of course, you remove the sfq qdisc from 10:256 and add 2 sfq qdiscs to
the 2 new classes.
