Fortinet FortiLink Protocol: The FortiLink protocol is Fortinet's proprietary mechanism for managing FortiSwitch units from a FortiGate firewall. It simplifies configuration and security policy enforcement across the connected network devices. Auto-Discovery: FortiLink's auto-discovery feature means that by default, all ports on a FortiSwitch will actively send out discovery frames. This allows them to locate a FortiGate device that has a FortiLink interface enabled, streamlining the device management process. No Configuration Needed: You don't have to manually configure individual ports for FortiLink discovery on FortiSwitch devices. Reference FortiSwitchOS FortiLink Guide (FortiSwitch Devices Managed by FortiOS 7.2): Refer to pages 13 and 14 for details on zero-touch management and FortiLink configuration.
