putting command " sudo x actions="load:0->OXM_OF_IN_PORT[]". If you

Dear RYU Team,
May I raise one question that how can I change or modify the ingress port
number in RYU controller. In OVS, we can simply put "load:0->OXM_OF_IN_PORT[]"
this statement at action field. In RYU controller,
how can i install that action.

Hello
Try to configure your OVS to support OF version 1.0, 1.1 , 1.2 and 1.3 at
the same time and lets see the result.

assign the flow entry reactively.

I assign the flow rules in each OF Switch to send packet-in message to RYU

is RYU controller receive the a lot of packet-in message from OF Switch.
