Description


This article provides steps to enable the usage of multiple VDOMs.

 

Scope

 

FortiGate.

Solution


The following commands are used to enable multiple VDOMs in different FortiOS versions.

In version 5.6 and 6.0.

 

config sys global
    set vdom-admin enable
end

 

In versions 6.2, 6.4 and 7.0 FortiOS, there are two VDOM modes.

'split-vdom': split-task VDOM mode simplifies deployments that require only one management VDOM and one traffic VDOM.
The management VDOM is used to manage the FortiGate, and cannot be used to process traffic.

The traffic VDOM provides separate security policies and is used to process all network traffic.

'multi-vdom': multiple, completely separate VDOMs are created.
Any VDOM can be the management VDOM, as long as it has internet access.

There are no 'inter-VDOM' links, and each VDOM is independently managed.

To enable 'multiple vdom's:

 

config sys global
    set vdom-mode multi-vdom   
end

 

To enable 'split-vdom':

 

config sys global
    set vdom-mode split-vdom
end

 

Additional to the above, starting from version 6.4 onwards, it is also possible to enable the following to prevent accidentally creating VDOMs in the CLI:

 

config system global
    set edit-vdom-prompt enable
end

 

This setting is disabled by default. Once enabled, when an administrator creates a new VDOM, the FortiGate displays a prompt to confirm before the VDOM is created.

 

config vdom
    edit vdomtest1
The input VDOM name doesn't exist.
Do you want to create a new VDOM?
Press 'y' to continue, or press 'n' to cancel. (y/n)y

 

 

To revert to single vdom scenario:

  • Make sure there are no interfaces assigned to any of the VDOMs (except the root VDOM)
  • Run the following command:

 

config system global

set vdom-mode no-vdom

 

Note:

FortiProxy versions below 7.0 do not support multi-VDOM configuration in any version. To enable multi-VDOM configuration in version 7.2.x and above, run the following command:

 

config system global

set vdom-mode multi-vdom

end
