Enabling Offline Mode shuts down the protocol used to communicate with managed devices. This is a feature you can use to troubleshoot problems, allowing you to change FortiManager unit settings without affect managed devices.

Select the ADOM mode, either Normal or Advanced.

Select to download the FortiManager unit’s Web Services Description Language (WSDL) file.

Web services is a standards-based, platform independent, access method for other hardware and software APIs. The file itself defines the format of commands the FortiManager will accept as well as the response to expect. Using the WSDL file, third-party or custom applications can communicate with the FortiManager unit and operate it or retrieve information just as an admin user would from the Web‑based Manager or CLI.

Enable chassis management.

Enter a chassis update interval from 14 to 1440 minutes (default is 15). This option is only available if chassis management is enabled.

Select to either automatically accept changes or to prompt the administrator to accept the changes.

Set a limit on the size of the task list.

Select to preview the installation before proceeding.

Select to manage and install interface based policies only instead of all device and policy configuration.
