The switches would delete the traffic flows or any flow that i add on it if it is not connected to controller from the beginning or if I remove them later on after getting connected . if the switches have flows and try to connect to controller which is not started, they would eventually delete all the flows that were added on them after few seconds. same happens if i stop the controller separately and l see the flows getting deleted. the flows remain if the controller is active and connected.
