For OpenFlow switches and controllers:

Active OpenFlow connection methods:

OpenFlow version options:
  -V, --version           display version information
  -O, --protocols         set allowed OpenFlow versions
                          (default: OpenFlow10, OpenFlow11, OpenFlow12, OpenFlow13, OpenFlow14, OpenFlow15)

  -v, --verbose            set maximum verbosity level
  --log-file[=FILE]        enable logging to specified FILE
                           (default: /var/log/openvswitch/ovs-ofctl.log)
