initialize the database without executing any other command.

.SS "Bridge Commands"
These commands examine and manipulate Open vSwitch bridges.

.SS "OpenFlow Controller Connectivity"
.
\fBovs\-vswitchd\fR can perform all configured bridging and switching
-locally, or it can be configured to connect a given bridge to an
-external OpenFlow controller, such as NOX.
+locally, or it can be configured to connect a given bridge to one or
+more external OpenFlow controllers, such as NOX.
.
-If a \fIbridge\fR argument is given, the settings apply only to the
-specified bridge. Otherwise, they apply to the Open vSwitch instance,
-and its configuration applies to any bridge that has not been explicitly
-configured through a \fIbridge\fR argument.
+For each of these commands, a \fIbridge\fR of \fBdefault\fR applies
+the configuration as the default for any bridge that has not been
+explicitly configured. Otherwise, \fIbridge\fR must name a bridge,
+and the settings apply only to that bridge. (Omitting \fIbridge\fR
+entirely usually has the same effect as specifying \fBdefault\fR.)

.IP "\fBget\-controller\fR [\fIbridge\fR]"
Prints the configured controller target.
.IP "\fBdel\-controller\fR [\fIbridge\fR]"
Deletes the configured controller target.

-Sets the configured controller target. The \fItarget\fR may use any of
-the following forms:
+.IP "\fBset\-controller\fR [\fIbridge\fR] \fItarget\fR\&..."

.IP "\fBInterface\fR"
A network device attached to a port. Records may be identified by
name.
+.IP "\fBMirror\fR"
+A port mirroring configuration attached to a bridge. Records may be
+identified by mirror name.
.IP "\fBController\fR"
Configuration for an OpenFlow controller. A controller attached to a
particular bridge may be identified by the bridge's name. The default
controller controller for an Open vSwitch may be identified by
specifying \fB.\fR as the record name.
-.IP "\fBMirror\fR"
-A port mirroring configuration attached to a bridge. Records may be
-identified by mirror name.
.IP "\fBNetFlow\fR"
A NetFlow configuration attached to a bridge. Records may be
identified by bridge name.

+The global SSL configuration for \fBovs\-vswitchd\fR. The record
+attached to the \fBOpen_vSwitch\fR table may be identified by

+.IP "\fBsFlow\fR"
+An sFlow configuration attached to a bridge. Records may be
+identified by bridge name.

Names of tables, records, and columns are not case-sensitive, and
\fB--\fR and \fB_\fR are treated interchangeably. Unique
escape special characters. The empty string must be represented as a
pair of double quotes (\fB""\fR).
.IP "UUID"
-A universally unique identifier in the style of RFC 4122,
-e.g. \fBf81d4fae-7dec-11d0-a765-00a0c91e6bf6\fR.

Multiple values in a single column may be separated by spaces or a
single comma. When multiple values are present, duplicates are not
or empty map, as appropriate. This command applies only to columns
that are allowed to be empty.

Creates a new record in \fItable\fR and sets the initial values of
each \fIcolumn\fR. Columns not explicitly set will receive their
default values. Outputs the UUID of the new row.

+If \fB@\fIname\fR is specified, then the UUID for the new row may be
