To configure the OpenFlow controller settings on the Zodiac WX which is running firmware version 1.20 or higher go to SYSTEM->STARTUP on the left-hand menu in the web UI. At the bottom of the startup page, you can find a listing of the rc.local file which contains the configuration settings for your OpenFlow Controller. There are two settings (see below) that you need to change for your OpenFlow controller, they are IP_CONTROLLER which is the IP address of your OpenFlow controller and PORT_CONTROLLER which is the TCP port your OpenFlow controller is listening on.
Change these two settings to the required values and then press Save & Apply at the bottom of the page to save these changes, then reboot the device to apply the settings. No other settings require changing and may result in you being unable to access the device. If there is an issue perform a factory reset by pressing and holding the reset button underneath the device for 20 seconds and then release and allow the device to restart. This will restore the configuration back to the default settings and allow you to again connect to the device.
