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 PD.
