Please read REPORTING-BUGS and pass along the information recommended in
In case you are not sure that your controller is configured correctly,
you might try using the "ovs-controller" program as a simple
controller. If you pass in the option "-vvconn" you can watch all of
the OpenFlow traffic going back and forth to it.

65534 is OFPP_LOCAL, the "local port" associated with the datapath
itself, e.g. with dp0.
1 is just the first ordinary OpenFlow port.
"ovs-ofctl dump-ports" will print the association between ports and
their OpenFlow port numbers.
