Correct, in secure mode switch will do nothing if a packet doesn't match a rule. The default action in OF1.3+ is to drop such packets. FWIW To simplify debug of the flows I'd recommend to add a fall-through flow in table 0, with the lowest priority 0, to send not matching packets to controller. In the controller you might just print headers of the not-matched packets. Сб, 19 марта 2016 г. в 0:24, Scott Lowe <scott.l...@scottlowe.org>:
