.SH DESCRIPTION
The \fBovs\-vsctl\fR program configures \fBovs\-vswitchd\fR(8) by
-providing a high\-level interface to editing its configuration
+providing a high\-level interface to its configuration
database. This program is mainly intended for use when
\fBovs\-vswitchd\fR is running. If it is used when
\fBovs\-vswitchd\fR is not running, then \fB\-\-no\-wait\fR should be
.PP
\fBovs\-vsctl\fR can perform any number of commands in a single run,
implemented as a single atomic transaction against the database.
-Commands are separated on the command line by \fB\-\-\fR arguments.
+.PP
+The \fBovs\-vsctl\fR command line begins with global options (see
+\fBOPTIONS\fR below for details). The global options are followed by
+one or more commands. Each command should begin with \fB\-\-\fR by
+itself as a command-line argument, to separate it from the global
+options and following commands. (If the first command does not have
+any options, then the first \fB\-\-\fR may be omitted.) The command
+itself starts with command-specific options, if any, followed by the
+command name and any arguments. See \fBEXAMPLES\fR below for syntax
+examples.

contacts to query or modify configuration. The default is

.
-.IP "\fBadd\-br \fIbridge\fR"
+.IP "[\fB\-\-may\-exist\fR] \fBadd\-br \fIbridge\fR"
Creates a new bridge named \fIbridge\fR. Initially the bridge will
have no ports (other than \fIbridge\fR itself).
+.IP
+Without \fB\-\-may\-exist\fR, attempting to create a bridge that
+exists is an error. With \fB\-\-may\-exist\fR, \fIbridge\fR may
+already exist (but it must be a real bridge, not a VLAN bridge).
.
-.IP "\fBadd\-br \fIbridge parent vlan\fR"
+.IP "[\fB\-\-may\-exist\fR] \fBadd\-br \fIbridge parent vlan\fR"
Creates a ``fake bridge'' named \fIbridge\fR within the existing Open
vSwitch bridge \fIparent\fR, which must already exist and must not
itself be a fake bridge. The new fake bridge will be on 802.1Q VLAN
\fIvlan\fR, which must be an integer between 1 and 4095. Initially
\fIbridge\fR will have no ports (other than \fIbridge\fR itself).
+.IP
+Without \fB\-\-may\-exist\fR, attempting to create a bridge that
+exists is an error. With \fB\-\-may\-exist\fR, \fIbridge\fR may
+already exist (but it must have the specified \fIvlan\fR and
+\fIparent\fR).
.
.IP "[\fB\-\-if\-exists\fR] \fBdel\-br \fIbridge\fR"
Deletes \fIbridge\fR and all of its ports. If \fIbridge\fR is a real
Lists all of the ports within \fIbridge\fR on standard output, one per
line. The local port \fIbridge\fR is not included in the list.
.
-.IP "\fBadd\-port \fIbridge port\fR"
+.IP "[\fB\-\-may\-exist\fR] \fBadd\-port \fIbridge port \fR[\fIcolumn\fR[\fB:\fIkey\fR]\fR=\fIvalue\fR]\&...\fR"
Creates on \fIbridge\fR a new port named \fIport\fR from the network
device of the same name.
+.IP
+Optional arguments set values of column in the Port record created by
+the command. For example, \fBtag=9\fR would make the port an access
+port for VLAN 9. The syntax is the same as that for the \fBset\fR
+command (see \fBDatabase Commands\fR below).
+.IP
+Without \fB\-\-may\-exist\fR, attempting to create a port that exists
+is an error. With \fB\-\-may\-exist\fR, \fIport\fR may already exist
+(but it must be on \fIbridge\fR and not be a bonded port).
.

+.IP "[\fB\-\-fake\-iface\fR] \fBadd\-bond \fIbridge port iface\fR\&... [\fIcolumn\fR[\fB:\fIkey\fR]\fR=\fIvalue\fR]\&...\fR"
Creates on \fIbridge\fR a new port named \fIport\fR that bonds
together the network devices given as each \fIiface\fR. At least two
interfaces must be named.
.IP
+Optional arguments set values of column in the Port record created by
+the command. The syntax is the same as that for the \fBset\fR command
+(see \fBDatabase Commands\fR below).
+.IP
With \fB\-\-fake\-iface\fR, a fake interface with the name \fIport\fR is
created. This should only be used for compatibility with legacy
software that requires it.
+.IP
+Without \fB\-\-may\-exist\fR, attempting to create a port that exists
+is an error. With \fB\-\-may\-exist\fR, \fIport\fR may already exist
+(but it must be on \fIbridge\fR and bond together exactly the
+specified interface).
.
.IP "[\fB\-\-if\-exists\fR] \fBdel\-port \fR[\fIbridge\fR] \fIport\fR"
Deletes \fIport\fR. If \fIbridge\fR is omitted, \fIport\fR is removed
not exist is an error. With \fB\-\-if\-exists\fR, attempting to
delete a port that does not exist has no effect.
.
+.IP "[\fB\-\-if\-exists\fR] \fB\-\-with\-iface del\-port \fR[\fIbridge\fR] \fIiface\fR"
+Deletes the port named \fIiface\fR or that has an interface named
+\fIiface\fR. If \fIbridge\fR is omitted, the port is removed from
+whatever bridge contains it; if \fIbridge\fR is specified, it must be
+the real or fake bridge that contains the port.
+.IP
+Without \fB\-\-if\-exists\fR, attempting to delete the port for an
+interface that does not exist is an error. With \fB\-\-if\-exists\fR,
+attempting to delete the port for an interface that does not exist has
+no effect.
+.
.IP "\fBport\-to\-br \fIport\fR"
Prints the name of the bridge that contains \fIport\fR on standard
output.

When a controller is configured, it is, ordinarily, responsible for
setting up all flows on the switch. Thus, if the connection to
the controller fails, no new network connections can be set up. If

Ordinarily, all of the files named in the SSL configuration must exist
