.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.

.SS "Linux VLAN Bridging Compatibility"
The \fBovs\-vsctl\fR program supports the model of a bridge
.SS "Bridge Commands"
These commands examine and manipulate Open vSwitch bridges.
.
-.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"
Creates on \fIbridge\fR a new port named \fIport\fR from the network
device of the same name.
+.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\&..."
Creates on \fIbridge\fR a new port named \fIport\fR that bonds
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.
