Description
This article describes that by default, all FortiGates support a maximum of 10 virtual domains (VDOMs) except the FortiGate-30B.
On high-end FortiGate models, it is possible to increase the number of VDOMs to 25, 50, 100, 250, or 500 by purchasing a license key from Fortinet.
Scope
FortiGate: model 3000 or higher (FortiGate-1240B supports 25 VDOMs).
FortiOS firmware - version 3.0 and higher.
Solution
To obtain a VDOM license key:
Record the FortiGate serial number. It is possible to find the serial number in the web-based manager on the System Status page.
Login on the Fortinet Support website, and use the serial number of the registered FortiGate to purchase a license key for 25, 50, 100, 250, or 500 VDOMs.
- When the license key is received, go to System -> Maintenance -> License on the FortiGate.
- In the License Key field, enter the 32-character license key received from Fortinet.
- Select Apply.
Since the release of FortiOS 5.2, upgrading VDOM licenses no longer requires a system reboot.
To verify the VDOM license was upgraded, go to the System Status page under License Information to confirm VDOMs Allowed are now the upgraded license number.
Vdom licenses are perpetual. It has no expiration date once applied. However, it is tied to a specific serial number.
In an HA cluster, ensure that all devices in the same cluster have the VDOM license, as the license is tied to the serial number.
Note:
When configuring 250 or more VDOMs, it is possible to experience performance issues.
