How do you enable VDOMs on a FortiGate device?

Enabling Virtual Domains (VDOMs) on a FortiGate device is achieved by executing the command "config system global" followed by setting "vdome-enable." This method allows the administrator to configure the global settings for the FortiGate appliance, which includes enabling the VDOM feature.

When VDOMs are enabled, the FortiGate device can be divided into multiple virtual units, each functioning independently with its own security policies, interfaces, and routing protocols. This capability is especially beneficial for organizations that require isolation between different departments, clients, or environments while utilizing a single hardware device.

Other options may include common tasks associated with configuration but do not directly enable VDOMs in the way described. For example, setting a specific interface does not change the global settings required to enable VDOMs. Accessing the web interface to enable VDOMs is not available as a configuration option; instead, the command line interface provides the necessary commands for this action. Lastly, updating the firmware can provide enhancements and new features but is not a precondition for enabling VDOMs on devices that support them.
