Hi, Thanks for the information, i could not find Packet_Outs and Packet_Ins messages....
I am running my mininet topology on the native machine and POX controller on the same machine.. To see the packets movements to different switches and controller, I would like to know, which interface I should look at ? Is it the Ethernet interface of my machine or the loopback interface ?
