Thanks Ben, I think we figured it out.
We want the controller to allocate port numbers to prevent the round trip when we create a port and wanted to understand what is a safe range to allocate through the ofport_request so we don’t have to worry about collisions with the vswitch allocated port numbers. We are running with > 32k.

    I don't really understand this question.  OpenFlow usually runs on port
    6653, or sometimes on the legacy port number 6633.
