Connects to \fIswitch\fR and prints to the console all OpenFlow

If \fImiss-len\fR is provided, \fBovs\-ofctl\fR sends an OpenFlow ``set
configuration'' message at connection setup time that requests
pairs of hexadecimal digits delimited by colons
(e.g. \fB00:0A:E4:25:6B:B0\fR).

.IP \fBdl_type=\fIethertype\fR

integer between 0 and 65535, inclusive, either in decimal or as a

+.IP \fBtable=\fInumber\fR
+If specified, limits the flow manipulation and flow dump commands to
+only apply to the table with the given \fInumber\fR.
+\fInumber\fR is a number between 0 and 254, inclusive.
+.
+Behavior varies if \fBtable\fR is not specified. For flow table
+modification commands without \fB\-\-strict\fR, the switch will choose
+the table for these commands to operate on. For flow table
+modification commands with \fB\-\-strict\fR, the command will operate
+on any single matching flow in any table; it will do nothing if there
+are matches in more than one table. The \fBdump-flows\fR and
+\fBdump-aggregate\fR commands will gather statistics about flows from
+all tables.

The following shorthand notations are also available:

.IP \fBlocal\fR
Outputs the packet on the ``local port,'' which corresponds to the
-\fBof\fIn\fR network device (see \fBCONTACTING THE CONTROLLER\fR in
-\fBovs\-openflowd\fR(8) for information on the \fBof\fIn\fR network device).

.IP \fBdrop\fR
Discards the packet, so no further processing or forwarding takes place.
1.0 and later. Otherwise, if \fIid\fR is a 64-bit value, it requires
Open vSwitch 1.1 or later.
.
-.IP \fBdrop_spoofed_arp\fR
-Stops processing further actions, if the packet being processed is an
-Ethernet+IPv4 ARP packet for which the source Ethernet address inside
-the ARP packet differs from the source Ethernet address in the
-Ethernet header.

-This action is deprecated in favor of defining flows using the
-\fBarp_sha\fR match field described earlier and will likely be removed
-in a future version of Open vSwitch.
-.
.IP \fBset_queue\fB:\fIqueue\fR
Sets the queue that should be used to \fIqueue\fR when packets are
output. The number of supported queues depends on the switch; some
The \fBdump\-flows\fR and \fBdump\-aggregate\fR commands support an
additional optional field:
.
-.IP \fBtable=\fInumber\fR
-If specified, limits the flows about which statistics are gathered to
-those in the table with the given \fInumber\fR. Tables are numbered
-as shown by the \fBdump\-tables\fR command.

.SH EXAMPLES
.
-The following examples assume that an OpenFlow switch on the local
-host has been configured to listen for management connections on a
-Unix domain socket named \fB@RUNDIR@/openflow.sock\fR, e.g. by
-specifying \fB\-\-listen=punix:@RUNDIR@/openflow.sock\fR on the
-\fBovs\-openflowd\fR(8) command line.
+The following examples assume that \fBovs\-vswitchd\fR has a bridge
+named \fBbr0\fR configured.
.
.TP
-\fBovs\-ofctl dump\-tables unix:@RUNDIR@/openflow.sock\fR
+\fBovs\-ofctl dump\-tables br0\fR
Prints out the switch's table stats. (This is more interesting after
some traffic has passed through.)
.
.TP
-\fBovs\-ofctl dump\-flows unix:@RUNDIR@/openflow.sock\fR
+\fBovs\-ofctl dump\-flows br0\fR
Prints the flow entries in the switch.
