The command ovs-vsctl is a utility for querying and configuring the Open vSwitch. The Open vSwitch configuration is kept in a database managed by the ovsdb-server process.The ovs-vsctl command connects to ovsdb-server, which maintains the Open vSwitch configuration database. Using this connection, ovs-vsctl queries and applies changes to the database, based on the supplied commands.

See ovs-vsctl help for more information about the utility.

ovs-vsctl(8)                                       Open vSwitch Manual                                       ovs-vsctl(8)
NAME
       ovs-vsctl - utility for querying and configuring ovs-vswitchd
SYNOPSIS
       ovs-vsctl [options] -- [options] command [args] [-- [options] command [args]]...
DESCRIPTION
       The  ovs-vsctl  program  configures ovs-vswitchd(8) by providing a high-level interface to its configuration data-
       base.  See ovs-vswitchd.conf.db(5) for comprehensive documentation of the database schema.
       ovs-vsctl connects to an ovsdb-server 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, by default it waits until ovs-vswitchd has finished reconfiguring itself before it  exits.
       (If you use ovs-vsctl when ovs-vswitchd is not running, use --no-wait.)
       ovs-vsctl  can  perform any number of commands in a single run, implemented as a single atomic transaction against
       the database.
       The ovs-vsctl command line begins with global options (see OPTIONS below for details).   The  global  options  are
       followed by one or more commands.  Each command should begin with -- by itself as a command-line argument, to sep-
       arate it from the following commands.  (The -- before the first command is optional.)  The command  itself  starts
       with  command-specific  options,  if  any, followed by the command name and any arguments.  See EXAMPLES below for
       syntax examples.
   Linux VLAN Bridging Compatibility
       The ovs-vsctl program supports the model of a bridge implemented by Open vSwitch, in which a  single  bridge  sup-
       ports  ports  on  multiple  VLANs.   In  this model, each port on a bridge is either a trunk port that potentially
       passes packets tagged with 802.1Q headers that designate VLANs or it is assigned a single implicit  VLAN  that  is
       never tagged with an 802.1Q header.
       For  compatibility  with  software designed for the Linux bridge, ovs-vsctl also supports a model in which traffic
       associated with a given 802.1Q VLAN is segregated into a separate bridge.  A special form of  the  add-br  command
       (see below) creates a ``fake bridge'' within an Open vSwitch bridge to simulate this behavior.  When such a ``fake
       bridge'' is active, ovs-vsctl will treat it much like a bridge separate from its ``parent bridge,'' but the actual
       implementation in Open vSwitch uses only a single bridge, with ports on the fake bridge assigned the implicit VLAN
       of the fake bridge of which they are members.  (A fake bridge for VLAN 0 receives packets that have no 802.1Q  tag
       or a tag with VLAN 0.)
