README.Debian for openvswitch-switch
---------------------------------
-* The switch must be configured before it can be used. To configure
- it interactively, install the openvswitch-switch-config package and run
- the ovs-switch-setup program. Alternatively, edit
- /etc/default/openvswitch-switch by hand, then start the switch manually
- with "/etc/init.d/openvswitch-switch start".
-
* To use the Linux kernel-based switch implementation, you will need
to build and install the Open vSwitch kernel module. To do so, install
the openvswitch-datapath-source package, then follow the instructions
* This package does not yet support the userspace datapath-based
switch implementation.

+Debian network scripts integration
+----------------------------------
+This package lets a user to optionally configure Open vSwitch bridges
+and ports from /etc/network/interfaces. Please refer to the interfaces(5)
+manpage for more details regarding /etc/network/interfaces.
+
+The stanzas that configure the OVS bridges should begin with "allow-ovs"
+followed by name of the bridge. Here is an example.
+allow-ovs br0
+
+The stanzas that configure the OVS ports should begin with
+"allow-${bridge-name}" followed by name of the port. Here is an example.
+allow-br0 eth0
+
+The following OVS specific "command" options are supported:
+
+ - ovs_type: This can either be OVSBridge, OVSPort, OVSIntPort or OVSBond
+ depending on whether you configure a bridge, port, an internal port or
+ a bond. This is a required option.
+
+ - ovs_ports: This option specifies all the ports that belong to a bridge.
+
+ - ovs_bridge: This options specifies a bridge to which a port belongs.
+ This is a required option for a port.
+
+ - ovs_bonds: This option specifies the list of physical interfaces to be
+ bonded together.
+
+ - ovs_options: This option lets you add extra arguments to a ovs-vsctl
+ command. See examples.
+
+ - ovs_extra: This option lets you run additional ovs-vsctl commands,
+ separated by "--" (double dash). Variables can be part of the "ovs_extra"
+ option. You can provide all the standard environmental variables
+ described in the interfaces(5) man page. You can also pass shell
+ commands.
+
+More implementation specific details can be seen in the examples.
+
+Examples:
+--------
+ex 1: A standalone bridge.

+ address 192.168.1.1
+ netmask 255.255.255.0
+ ovs_type OVSBridge
+
+ex 2: A bridge with one port.
+
+allow-ovs br0

+ ovs_ports eth0
+
+allow-br0 eth0
+iface eth0 inet manual
+ ovs_bridge br0
+ ovs_type OVSPort
+
+ex 3: A bridge with multiple physical ports.
