Default VDOM configuration
By default when the FortiGate-7000 first starts up it is operating in multiple VDOM mode. The system has a management VDOM (named dmgmt-vdom) and the root VDOM. All management interfaces are in dmgmt-vdom and all other interfaces are in the root VDOM. You can add more VDOMs and add interfaces to them or just use the root VDOM.
Default management VDOM
By default the FortiGate-7000 configuration includes a management VDOM named dmgmt-vdom. For the FortiGate-7000 system to operate normally you should not change the configuration of this VDOM and this VDOM should always be the management VDOM. You should also not add or remove interfaces from this VDOM.
You have full control over the configurations of other FortiGate-7000 VDOMs.
