Hi Ben, Thanks for your response.
I want to use OVS APIs to inform the controller about port shutdown. But, I don't find any direct API/function to do so. For example, *ofproto_port_add() *could be called to add a port into an openflow bridge and *ofproto_port_del() *can be called to remove a port from Openflow bridge and in each of the scenario, the OVS will send port add and delete message to the controller so that the controller will be aware of it. Now, i am bringing one of the openlow port to down state i.e. admin down. In this case, i want to call an API/function of OVS which can inform the controller about port state change. AFAIK, there is no *ofproto API *to inform the controller. Can someone guide me how to accomplish this? I am trying to delete the port from the bridge then add it once again whenever the port is set to admin down. But, I am suspecting this approach might create some other issue. Please help me on this. Thanks, Kals.
