Overview
Indigo Virtual Switch (IVS) is a pure OpenFlow virtual switch designed for high performance and minimal administration. It is built on the Indigo platform, which provides a common core for many physical and virtual switches.

Build and Install
| Code Block |

cd ivs make |
The IVS daemon and ivs-ctl utility will be written to
| Code Block |
|---|
targets/ivs/build/gcc-local/bin/ivs
targets/ivs-ctl/build/gcc-local/bin/ivs-ctl
|
Copy it to the sbin directory
| Code Block |
|---|
sudo cp targets/ivs/build/gcc-local/bin/ivs targets/ivs-ctl/build/gcc-local/bin/ivs-ctl /usr/sbin |
Running IVS
Controller configuration
You'll need an OpenFlow controller to use IVS. We suggest Floodlight, which should work out of the box. Follow your controller's instructions to get it running and note down its IP address.
Kernel Module
The openvswitch kernel module must be loaded:
| Code Block |
|---|
modprobe openvswitch
|
Run the IVS daemon
You'll need to tell it the IP address of the controller (-c) and the initial set of network interfaces to connect (-i). Here's an example command line:
| Code Block |
|---|
sudo ivs -c 192.168.1.10 -i eth1 -i eth2 |
IVS will immediately begin communicating with the controller and, depending on your controller's configuration, forwarding traffic between eth1 and eth2.
| Code Block |
|---|
ivs-ctl add-port |
and
| Code Block |
|---|
ivs-ctl del-port |
can be used to add and remove ports at runtime (for example, this is used by hypervisors when a VM is started). See the ivs-ctl reference for more more details.
