Regarding the scenario where a FortiSwitch did not reboot after the authorization process while the

other devices did, the most likely cause, given the configuration settings in the exhibit, is:

The management mode was set to use FortiLink mode (Option B): If the FortiSwitch was already

configured to use FortiLink for its management mode, it may not require a reboot to complete the

authorization process as its management interface settings are already aligned with FortiLink

requirements. This is unlike switches that might be transitioning from a standalone or another

management mode, which would typically require a reboot to apply new management settings fully.

Reference:

FortiLink mode specifically tailors FortiSwitch to be managed via a FortiGate device, integrating its

operation into the wider security fabric without needing a reboot if it is already set to this mode

before authorization. This contrasts with other management modes where transitioning to FortiLink

could necessitate a system restart to initialize the new configuration.
