thank you murphy for your reply. i know that the action for entry can be set to send any packet that match rule to controller, but my intention is like this. I want to purposely set entry action as "drop" at first. After that the packet that hit the entry will timeout and retransmit (same header info). when the second packet hit the entry, i want the packet to notify/to be sent to controller for further action. Is it possible?thank you murphy for your hint and help
