Description This article describes how the FortiManager license count works for FortiGate with VDOM enabled.
Scope FortiManager.
Solution
  1. FortiManager licenses count only to the Traffic-type VDOM.
  2. Admin-type VDOMs are excluded from the license count.

 

Example:

In FortiGate:

  • 4 different VDOMs have been configured: 1 VDOM as Admin-type VDOM, and 3 VDOMs as Traffic-type VDOMs.

In FortiManager:

  • Run the following CLI command:

 

diagnose dvm device list

 

  • The result will show that currently FortiManager is managing 4 devices/VDOMs, but the license only counts as 3 devices/VDOMs.

License count rules for FortiManager-VM, Cloud (Fortinet, Azure, or AWS), and Hardware:

  • VDOM disabled: 1 FortiGate = 1 license.

  • VDOM enabled: 1 VDOM = 1 license.

  • FortiAnalyzer will be considered as 1 license.
  • Unregistered device in root ADOM: 1 unregistered device = 1 license. Hidden devices are not counted.

Excluded VDOMs

  • The Global VDOM is not included in the license count.

  • 'Admin' type VDOMs are not included in the license count. Only 'Traffic' type VDOMs are counted.
