The FAQ says:

Q: What versions of OpenFlow does Open vSwitch support?

    A: The following table lists the versions of OpenFlow supported by each
    version of Open vSwitch:

    =============== ===== ===== ===== ===== ===== ===== =====
    Open vSwitch    OF1.0 OF1.1 OF1.2 OF1.3 OF1.4 OF1.5 OF1.6
    =============== ===== ===== ===== ===== ===== ===== =====
    1.9 and earlier  yes   ---   ---   ---   ---   ---   ---
    1.10, 1.11       yes   ---   (*)   (*)   ---   ---   ---
    2.0, 2.1         yes   (*)   (*)   (*)   ---   ---   ---
    2.2              yes   (*)   (*)   (*)   (%)   (*)   ---
    2.3, 2.4         yes   yes   yes   yes   (*)   (*)   ---
    2.5, 2.6, 2.7    yes   yes   yes   yes   (*)   (*)   (*)
    2.8              yes   yes   yes   yes   yes   (*)   (*)
    =============== ===== ===== ===== ===== ===== ===== =====

    --- Not supported.
    yes Supported and enabled by default
    (*) Supported, but missing features, and must be enabled by user.
    (%) Experimental, unsafe implementation.

    In any case, the user may override the default:

    - To enable OpenFlow 1.0, 1.1, 1.2, and 1.3 on bridge br0::

          $ ovs-vsctl set bridge br0 \
              protocols=OpenFlow10,OpenFlow11,OpenFlow12,OpenFlow13

    - To enable OpenFlow 1.0, 1.1, 1.2, 1.3, 1.4, and 1.5 on bridge br0::

          $ ovs-vsctl set bridge br0 \
              protocols=OpenFlow10,OpenFlow11,OpenFlow12,OpenFlow13,OpenFlow14,OpenFlow15

    - To enable only OpenFlow 1.0 on bridge br0::

          $ ovs-vsctl set bridge br0 protocols=OpenFlow10

    All current versions of ovs-ofctl enable only OpenFlow 1.0 by default.  Use
    the -O option to enable support for later versions of OpenFlow in
    ovs-ofctl.  For example::

        $ ovs-ofctl -O OpenFlow13 dump-flows br0

    (Open vSwitch 2.2 had an experimental implementation of OpenFlow 1.4 that
    could cause crashes.  We don't recommend enabling it.)

    :doc:`/topics/openflow` tracks support for OpenFlow 1.1 and later features.
    When support for OpenFlow 1.5 and 1.6 is solidly implemented, Open vSwitch
    will enable those version by default.
