ovs-testcontroller: OpenFlow controller
usage: ovs-testcontroller [OPTIONS] METHOD
where METHOD is any OpenFlow connection method.

Active OpenFlow connection methods:
  tcp:HOST[:PORT]         PORT (default: 6653) at remote HOST
  ssl:HOST[:PORT]         SSL/TLS PORT (default: 6653) at remote HOST
  unix:FILE               Unix domain socket named FILE
Passive OpenFlow connection methods:
  ptcp:[PORT][:IP]        listen to TCP PORT (default: 6653) on IP
  pssl:[PORT][:IP]        listen for SSL/TLS on PORT (default: 6653) on IP
  punix:FILE              listen on Unix domain socket FILE
PKI configuration (required to use SSL/TLS):
  -p, --private-key=FILE  file with private key
  -c, --certificate=FILE  file with certificate for private key
  -C, --ca-cert=FILE      file with peer CA certificate

Daemon options:
  --detach                run in background as daemon
  --monitor               creates a process to monitor this daemon
  --user=username[:group] changes the effective daemon user:group
  --no-chdir              do not chdir to '/'
  --pidfile[=FILE]        create pidfile (default: /run/openvswitch/ovs-testcontroller.pid)
  --overwrite-pidfile     with --pidfile, start even if already running

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

Logging options:
  -vSPEC, --verbose=SPEC   set logging levels
  -v, --verbose            set maximum verbosity level
  --log-file[=FILE]        enable logging to specified FILE
                           (default: /var/log/openvswitch/ovs-testcontroller.log)
  --syslog-method=(libc|unix:file|udp:ip:port)
                           specify how to send messages to syslog daemon
  --syslog-target=HOST:PORT  also send syslog msgs to HOST:PORT via UDP

Other options:
  -H, --hub               act as hub instead of learning switch
  -n, --noflow            pass traffic, but don't add flows
  --max-idle=SECS         max idle time for new flows
  -N, --normal            use OFPP_NORMAL action
  -w, --wildcards[=MASK]  wildcard (specified) bits in flows
  -q, --queue=QUEUE-ID    OpenFlow queue ID to use for output
  -Q PORT-NAME:QUEUE-ID   use QUEUE-ID for frames from PORT-NAME
  --with-flows FILE       use the flows from FILE
  --unixctl=SOCKET        override default control socket name
  -h, --help              display this help message
  -V, --version           display version information
