.TP
-\fBadd\-dp \fIdp\fR [\fInetdev\fR...]
-Creates datapath \fIdp\fR. The name of the new datapath's local port
-depends on how \fIdp\fR is specified: if it takes the form
-\fBdp\fIN\fR, the local port will be named \fBdp\fIN\fR; otherwise,
-the local port's name will be \fIdp\fR.
+\fBadd\-dp \fIdp\fR [\fInetdev\fR[\fB,\fIoption\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
-This will fail if the host already has 256 datapaths, if a network
-device with the same name as the new datapath's local port already
-exists, or if \fIdp\fR is given in the form \fBdp\fIN\fR
-and a datapath numbered \fIN\fR already exists.
-.IP
-If \fInetdev\fRs are specified, \fBovs\-dpctl\fR adds them to the datapath.

.TP
-\fBadd\-if \fIdp netdev\fR[\fIoption\fR...]...
+\fBadd\-if \fIdp netdev\fR[\fB,\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

.
.RS
-.IP "\fBinternal\fR"
-Instead of attaching an existing \fInetdev\fR, creates an internal
-port (analogous to the local port) with that name.
+.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.
+.
+.IP "\fBset\-if \fIdp port\fR[\fB,\fIoption\fR]..."
+Reconfigures each \fIport\fR in \fIdp\fR as specified. An
+\fIoption\fR of the form \fIkey\fB=\fIvalue\fR adds the specified
+key-value option to the port or overrides an existing key's value. An
+\fIoption\fR of the form \fIkey\fB=\fR, that is, without a value,
+deletes the key-value named \fIkey\fR. The type of a port cannot be
+changed, so \fBtype=\fItype\fR is only allowed if \fItype\fR is the
+port's existing type.
.TP
\fBdel\-if \fIdp netdev\fR...
Removes each \fInetdev\fR from the list of network devices datapath
\fIdp\fR monitors.
.

-\fBdump-dps\fR
+\fBdump\-dps\fR
Prints the name of each configured datapath on a separate line.
.
.TP
-\fBshow \fR[\fIdp\fR...]
+[\fB\-s\fR | \fB\-\-statistics\fR] \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.)
+port is identified as port 0.) If \fB\-s\fR or \fB\-\-statistics\fR
+is specified, then packet and byte counters are also printed for each

.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.
.
-.IP "\fBdump-flows \fIdp\fR"
+.IP "\fBdump\-flows \fIdp\fR"
Prints to the console all flow entries in datapath \fIdp\fR's
flow table.
.IP
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"
+.IP "\fBdel\-flows \fIdp\fR"
Deletes all flow entries from datapath \fIdp\fR's flow table.

This command is primarily useful for debugging Open vSwitch. As
-discussed in \fBdump-flows\fR, these entries are
+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 "\fBdump-groups \fIdp\fR"
-Prints to the console the sets of port groups maintained by datapath
-\fIdp\fR. Ordinarily there are at least 2 port groups in a datapath
-that \fBovs\-openflowd\fR or \fBovs\-vswitch\fR is controlling: group
-0 contains
-all ports except those disabled by STP, and group 1 contains all
-ports. Additional or different groups might be used in the future.
