ovs−ofctl is a utility for managing OpenFlow switches. ovs-ofctl should work with any OpenFlow switch, not just Open vSwitch.

Users can view the ovs-ofctl help for more information about the utility.

  dump-groups SWITCH [GROUP]  print group description
  dump-group-stats SWITCH [GROUP]  print group statistics
  queue-get-config SWITCH PORT  print queue information for port
  add-meter SWITCH METER      add meter described by METER
  mod-meter SWITCH METER      modify specific METER
  del-meter SWITCH METER      delete METER
  del-meters SWITCH           delete all meters
  dump-meter SWITCH METER     print METER configuration
  dump-meters SWITCH          print all meter configuration
  meter-stats SWITCH [METER]  print meter statistics
  meter-features SWITCH       print meter features
For OpenFlow switches and controllers:
  probe TARGET                probe whether TARGET is up
  ping TARGET [N]             latency of N-byte echos
  benchmark TARGET N COUNT    bandwidth of COUNT N-byte echos
SWITCH or TARGET is an active OpenFlow connection method.
Other commands:
  ofp-parse FILE              print messages read from FILE
  mod-temp-thresh SWITCH THRESHOLD  modify temperature threshold
  dump-temp-thresh SWITCH     print temperature threshold
  ofp-parse-pcap PCAP         print OpenFlow read from PCAP
  dump-tables-desc SWITCH     print tables description
  bundle SWITCH MSG           send bundle messages
Active OpenFlow connection methods:
  tcp:IP[:PORT]           PORT (default: 6633) at remote IP
  ssl:IP[:PORT]           SSL PORT (default: 6633) at remote IP
  unix:FILE               Unix domain socket named FILE
PKI configuration (required to use SSL):
  -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
  --no-chdir              do not chdir to '/'
  --pidfile[=FILE]        create pidfile (default: /ovs/var/run/openvswitch/
  --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)
Logging options:
  -vSPEC, --verbose=SPEC   set logging levels
  -v, --verbose            set maximum verbosity level
  --log-file[=FILE]        enable logging to specified FILE
                           (default: /ovs/var/log/openvswitch/ovs-ofctl.log)

       ovs-ofctl - administer OpenFlow switches
       ovs-ofctl [options] command [switch] [args...]
       The ovs-ofctl program is a command line tool for monitoring and administering OpenFlow switches.  It can also show
       the current state of an OpenFlow switch, including features, configuration, and table  entries.   It  should  work
       with any OpenFlow switch, not just Open vSwitch.
   OpenFlow Switch Management Commands
       These commands allow ovs-ofctl to monitor and administer an OpenFlow switch.  It is able to show the current state
       of a switch, including features, configuration, and table entries
