Please read the FAQ.
Q: What versions of OpenFlow does Open vSwitch support?
A: Open vSwitch 1.9 and earlier support only OpenFlow 1.0 (plus
extensions that bring in many of the features from later versions
of OpenFlow).
Open vSwitch 1.10 and later have experimental support for OpenFlow
1.2 and 1.3. On these versions of Open vSwitch, the following
command enables OpenFlow 1.0, 1.2, and 1.3 on bridge br0:
ovs-vsctl set bridge br0 protocols=OpenFlow10,OpenFlow12,OpenFlow13
Open vSwitch version 2.0 and later will have experimental support
for OpenFlow 1.1, 1.2, and 1.3. On these versions of Open vSwitch,
the following command enables OpenFlow 1.0, 1.1, 1.2, and 1.3 on
bridge br0:
ovs-vsctl set bridge br0
protocols=OpenFlow10,OpenFlow11,OpenFlow12,OpenFlow13
Use the -O option to enable support for later versions of OpenFlow
in ovs-ofctl. For example:
ovs-ofctl -O OpenFlow13 dump-flows br0
Support for OpenFlow 1.1, 1.2, and 1.3 is still incomplete. Work
to be done is tracked in OPENFLOW-1.1+ in the Open vSwitch sources
(also via http://openvswitch.org/development/openflow-1-x-plan/).
When support for a given OpenFlow version is solidly implemented,
Open vSwitch will enable that version by default.

Does your controller support OpenFlow 1.3?
