.SH DESCRIPTION
The \fBovs\-vsctl\fR program configures \fBovs\-vswitchd\fR(8) by
-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
-specified and configuration changes will only take effect when
-\fBovs\-vswitchd\fR is started.
-.PP
-By default, each time \fBovs\-vsctl\fR runs, it connects to an
-\fBovsdb\-server\fR process that maintains an Open vSwitch
-configuration database. Using this connection, it queries and
-possibly applies changes to the database, depending on the supplied
-commands. Then, if it applied any changes, it waits until
-\fBovs\-vswitchd\fR has finished reconfiguring itself before it exits.
+providing a high\-level interface to its configuration database.
+See \fBovs\-vswitchd.conf.db\fR(5) for comprehensive documentation of
+the database schema.

+connection, it queries and possibly applies changes to the database,

.PP
\fBovs\-vsctl\fR can perform any number of commands in a single run,
implemented as a single atomic transaction against the database.
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

+commands. (The \fB\-\-\fR before the first command is optional.) The

itself starts with command-specific options, if any, followed by the
command name and any arguments. See \fBEXAMPLES\fR below for syntax
examples.

.SH OPTIONS

.IP "\fB\-\-db=\fIserver\fR"
Sets \fIserver\fR as the database server that \fBovs\-vsctl\fR
contacts to query or modify configuration. The default is
-\fBunix:@RUNDIR@/ovsdb\-server\fR. \fIserver\fR must take one of the
+\fBunix:@RUNDIR@/db.sock\fR. \fIserver\fR must take one of the
following forms:

-reconfigure itself according to the the modified database. This

option should be used if \fBovs\-vswitchd\fR is not running;

.IP
This option has no effect if the commands specified do not change the
changes that it makes to the system log. This option disables this
logging.
.IP
-This option is equivalent to \fB\-\-verbose=vvsctl:syslog:warn\fR.
+This option is equivalent to \fB\-\-verbose=vsctl:syslog:warn\fR.
.
.IP "\fB\-\-oneline\fR"
Modifies the output format so that the output for each command is printed
lines are printed as \fB\\n\fR, and any instances of \fB\\\fR that
would otherwise appear in the output are doubled.
Prints a blank line for each command that has no output.
+This option does not affect the formatting of output from the
+\fBlist\fR or \fBfind\fR commands; see \fBTable Formatting Options\fR

.IP "\fB\-\-dry\-run\fR"
Prevents \fBovs\-vsctl\fR from actually modifying the database.
.
-.IP "\fB-t \fIsecs\fR"
-.IQ "\fB--timeout=\fIsecs\fR"
-Limits runtime to approximately \fIsecs\fR seconds. A value of
-zero will cause \fBovs\-vsctl\fR to wait forever. If the timeout expires,
-\fBovs\-vsctl\fR will exit with a \fBSIGALRM\fR signal. If this option is
-not used, \fBovs\-vsctl\fR uses a timeout of five seconds.
-(A timeout would normally happen only if the database cannot be contacted.)
+.IP "\fB\-t \fIsecs\fR"
+.IQ "\fB\-\-timeout=\fIsecs\fR"
+By default, or with a \fIsecs\fR of \fB0\fR, \fBovs\-vsctl\fR waits
+forever for a response from the database. This option limits runtime
+to approximately \fIsecs\fR seconds. If the timeout expires,
+\fBovs\-vsctl\fR will exit with a \fBSIGALRM\fR signal. (A timeout
+would normally happen only if the database cannot be contacted, or if
+the system is overloaded.)
+.
+.IP "\fB\-\-retry\fR"
+Without this option, if \fBovs\-vsctl\fR connects outward to the
+database server (the default) then \fBovs\-vsctl\fR will try to
+connect once and exit with an error if the connection fails (which
+usually means that \fBovsdb\-server\fR is not running).
+.IP
+With this option, or if \fB\-\-db\fR specifies that \fBovs\-vsctl\fR
+should listen for an incoming connection from the database server,
+then \fBovs\-vsctl\fR will wait for a connection to the database
+forever.
+.IP
+Regardless of this setting, \fB\-\-timeout\fR always limits how long
+\fBovs\-vsctl\fR will wait.

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

responsibility for setting up
flows when no message has been received from the controller for three
