The topology you show is what's usually referred to as "in-band control". At least in the ideal case, it doesn't alter how the controller interacts with the switches at all. All that matters is that the controller can communicate with the switches: whether it's through a separate control network, the same network as the data, or any other configuration is (hopefully) irrelevant.
So the short answer is that it shouldn't matter and the POX discovery application should work the same in both cases. -- Murphy On Sep 26, 2013, at 10:15 PM, Windhya Rankothge <[email protected]> wrote: > Hi all, > > My question is about a physical network like following, where POX controller > is physically directly connected to S1, but it controlls both S1 and S2 > > C1 > I > S1 --- S2 > > In this case, for the openflow topology discovery, does POX controller send > LLDP packets to both switches which are controlled by it, or does it send to > LLDP packet only to S1 which is directly connected to controller ?? > > Highly appreciate your thoughts.. > > Best Regards, > > Windhya Rankothge.....
