This probably depends on which address you're using to communicate between the switches in the Mininet topology and the controller. If you're using a loopback address (e.g., 127.0.0.1), it should be a loopback adapter. When in doubt, try it.
You can also use POX to produce capture files using the openflow.debug component, which can then be read in Wireshark. -- Murphy On Sep 30, 2013, at 9:12 AM, Windhya Rankothge <[email protected]> wrote: > Hi all, > > I am running my mininet topology on the native machine and POX controller on > the same machine..
