.SH NAME
.SH DESCRIPTION
.PP
The \fBovs\-dpctl\fR program can create, modify, and delete Open vSwitch
-datapaths. A single machine may host up to 256 datapaths (numbered 0
-to 255).
+datapaths. A single machine may host any number of datapaths.
+.PP
+This program works only with datapaths that are implemented outside of
+\fBovs\-vswitchd\fR itself, such as the Linux and Windows kernel-based
+datapaths. To manage datapaths that are integrated into
+\fBovs\-vswitchd\fR, such as the userspace (\fBnetdev\fR) datapath,
+use \fBovs\-appctl\fR(8) to invoke the \fBdpctl/*\fR commands, which
+are documented in \fBovs\-vswitchd\fR(8).
.PP
A newly created datapath is associated with only one network device, a
virtual network device sometimes called the datapath's ``local port''.
.PP
The following commands manage datapaths.
.
-.TP
-\fBadd\-dp \fIdp\fR [\fInetdev\fR...]
-Creates datapath \fIdp\fR, with a local port also named \fIdp\fR.
-This will fail if a network device \fIdp\fR already exists.
-.IP
-If \fInetdev\fRs are specified, \fBovs\-dpctl\fR adds them to the datapath.
-.
-.TP
-\fBdel\-dp \fIdp\fR
-Deletes datapath \fIdp\fR. If \fIdp\fR is associated with any network
-devices, they are automatically removed.
-.
-.TP
-\fBadd\-if \fIdp netdev\fR[\fIoption\fR...]...
-Adds each \fInetdev\fR to the set of network devices datapath
-\fIdp\fR monitors, where \fIdp\fR is the name of an existing
-datapath, and \fInetdev\fR is the name of one of the host's
-network devices, e.g. \fBeth0\fR. Once a network device has been added
-to a datapath, the datapath has complete ownership of the network device's
-traffic and the network device appears silent to the rest of the
-system.
-.IP
-A \fInetdev\fR may be followed by a comma-separated list of options.
-The following options are currently supported:
-.
-.RS
-.IP "\fBtype=\fItype\fR"
-Specifies the type of port to add. The default type is \fBsystem\fR.
-.IP "\fIkey\fB=\fIvalue\fR"
-Adds an arbitrary key-value option to the port's configuration.
-.RE
-.IP
-\fBovs\-vswitchd.conf.db\fR(5) documents the available port types and
-options.

.
-.TP
-\fBdel\-if \fIdp netdev\fR...
-Removes each \fInetdev\fR from the list of network devices datapath
-\fIdp\fR monitors.
-.
-.TP
-\fBdump\-dps\fR
-Prints the name of each configured datapath on a separate line.
-.
-.TP
-\fBshow \fR[\fIdp\fR...]
-Prints a summary of configured datapaths, including their datapath
-numbers and a list of ports connected to each datapath. (The local
-port is identified as port 0.)
-.IP
-If one or more datapaths are specified, information on only those
-datapaths are displayed. Otherwise, \fBovs\-dpctl\fR displays information
-about all configured datapaths.
+.SH OPTIONS
+.IP "\fB\-s\fR"
+.IQ "\fB\-\-statistics\fR"
+Causes the \fBshow\fR command to print packet and byte counters for
+each port within the datapaths that it shows.
.
-.IP "\fBdump\-flows \fIdp\fR"
-Prints to the console all flow entries in datapath \fIdp\fR's
-flow table.
-.IP
-This command is primarily useful for debugging Open vSwitch. The flow
-table entries that it displays are not
-OpenFlow flow entries. Instead, they are different and considerably
-simpler flows maintained by the Open vSwitch kernel module.
-.IP "\fBdel\-flows \fIdp\fR"
-Deletes all flow entries from datapath \fIdp\fR's flow table.
-.IP
-This command is primarily useful for debugging Open vSwitch. As
-discussed in \fBdump\-flows\fR, these entries are
-not OpenFlow flow entries. By deleting them, the process that set them
-up may be confused about their disappearance.
+.IP "\fB\-m\fR"
+.IQ "\fB\-\-more\fR"
+Increases the verbosity of \fBdump\-flows\fR output.
.
-.SH OPTIONS
-.TP
-\fB\-t\fR, \fB\-\-timeout=\fIsecs\fR
+.IP "\fB\-t\fR"
+.IQ "\fB\-\-timeout=\fIsecs\fR"
Limits \fBovs\-dpctl\fR runtime to approximately \fIsecs\fR seconds. If
the timeout expires, \fBovs\-dpctl\fR will exit with a \fBSIGALRM\fR
signal.

-.SH EXAMPLES
-.
-A typical \fBovs\-dpctl\fR command sequence for controlling an
-Open vSwitch kernel module:
-.
-.TP
-\fBovs\-dpctl add\-dp dp0\fR
-Creates datapath number 0.
-.
-.TP
-\fBovs\-dpctl add\-if dp0 eth0 eth1\fR
-Adds two network devices to the new datapath.
-.
-.PP
-At this point one would ordinarily start \fBovs\-openflowd\fR(8) on
-\fBdp0\fR, transforming \fBdp0\fR into an OpenFlow switch. Then, when
-the switch and the datapath is no longer needed:
-.
-.TP
-\fBovs\-dpctl del\-if dp0 eth0 eth1\fR
-Removes network devices from the datapath.
-.
-.TP
-\fBovs\-dpctl del\-dp dp0\fR
-Deletes the datapath.
