Hmm, there appears to be a lack of clarity regarding what a "switch port" means and what "multiple controllers" actually means.
But really this isn't a NOX issue, so you should try to clearly and accurately describe the problem you are seeing and then post it to mininet-discuss. [On a more NOX-related note I might mention that we are fixing the NOX controller class in Mininet to make it work better, for example being able to type mn --controller nox,pyswitch to have Mininet start up NOX with the pyswitch module.] On Jun 1, 2012, at 11:41 AM, Murphy McCauley wrote: > I'm pretty sure that the last time I checked, Mininet only had partial > support for multiple controllers.
