Hi, Could you tell me what functions are triggered when a switch gets connected to controller and how does it get the node ID of the switch. Where and through what function does the controller keep information about the switch as soon as it gets connected.

Hi , By quick looking the code, DataListener will update the DataStore whenever some changes in the topology and also refresh the graph and add flows to the connected device. So I think you can fetch the nodeId by looking into datastore. Refer this link -> link text (here you can see the code for looking into DataStore to fetch details of Node) It might helpful..

Thanks, -Karthik
