So we do need connectivity from controller?Because when we connect to controller,it starts learning and it might put the high priority entries in the flow table which will get compared before my manual entry and that way my entries will be of no use. My knowledge is limited in this as of now,so at this point of time it looks to me that we must connect to controller else switch will move to fail-safe mode and it will start broadcasting the packets?
