Hi Iwase, Thanks for the suggestion. I changed from OpenFlow 1.2 to OpenFlow 1.0. It worked. Now our controller connects to OpenFlow Switch.

It seems that Ryu sent OFPT_HELLO message with OpenFlow 1.2. How about specifying OpenFlow version in your RyuApp as follows? https://github.com/osrg/ryu/blob/master/ryu/app/simple_switch.py#L33 Thanks, Iwase On 2016年04月05日 18:16, HENRYDOSS, JAMES wrote: > Hi Iwase, > > Thanks for the quick feedback.
