  1. openflow appears to be provided by openvswitch-controller; apt-cache policy openvswitch-controller should show you the version installed.

  2. The version of openvswitch can be determined with ovs−ctl version, but that won't necessarily tell you the version of "OpenFlow" that is supported by that version. To do that, you'll need to cross reference it against the openvswitch web site or source. Per http://git.openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=blob_plain;f=FAQ;hb=HEAD:

    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.

  3. You can run the following command to show the version of openflow being run. I am using openvswitch v2.17

    $ovs-ofctl -V
ovs-ofctl (Open vSwitch) 2.17.2
OpenFlow versions 0x1:0x6

    0x1:0x6 = "1.6"
