Hi, Something I discovered with the latest git pull code:
Using the same interface in a fromdevice and todevice element, seems to cause a loop e.g. Eth0 receives 1 pps but transmits e.g. 80k pps @ 1500bytes or line rate 1gbps. This can be replicated with the config below: FromDevice(eth0, PROMISC true)->Queue->ToDevice(eth0); To test this the following example can be used at the source of the packets: // Where ethX is connected to eth0: RatedSource(DATA \<DATA>, RATE 1, LIMIT 10, ACTIVE true, STOP true) -> Queue -> ToDevice(ethX); FromDevice(ethX, PROMISC true) -> c::Counter -> Queue -> Discard; Script( wait 1, print c.rate, loop ); Changing the interface in the ToDevice to a different interface e.g. eth1 solves the problem... When adding another fromdevice and todevice pair even with different interfaces (as long as a fromdevice interface and todevice interface match somewhere in the config) the problem returns e.g FromDevice(eth0, PROMISC true)->Queue->ToDevice(eth1); FromDevice(eth1, PROMISC true)->Queue->ToDevice(eth0); I have checked whether this is because of promiscuous mode but found the same result when removing promisc and using EtherEncap.
