NAME
ovs-appctl - utility for configuring running Open vSwitch daemons
SYNOPSIS
ovs-appctl [--target=target | -t target] command [arg...]
ovs-appctl --help
ovs-appctl --version
DESCRIPTION
Open vSwitch daemons accept certain commands at runtime to control
their behavior and query their settings. Every daemon accepts a common
set of commands documented under COMMON COMMANDS below. Some daemons
support additional commands documented in their own manpages.
ovs-vswitchd in particular accepts a number of additional commands doc-
umented in ovs-vswitchd(8).
The ovs-appctl program provides a simple way to invoke these commands.
The command to be sent is specified on ovs-appctl's command line as
non-option arguments. ovs-appctl sends the command and prints the dae-
mon's response on standard output.
