For the FOS-VM to become fully operational, it has to be authorized by FortiMeter. Once the FOS-VM is added to FortiManager (promoted), it can then be managed by the FortiMeter module. If it can register, then the “FortiMeter grace period” value is set to 15 days. If the FOS-VM does not or cannot register to a FortiManager instance before the grace period timer elapses, then the license status becomes “Invalid” and the FOS-VM ceases functioning. The VM then starts to register to the FortiManager instance that is defined in its configuration file.
