"The tool is a Python script that converts the supported settings in a FortiSwitch standalone configuration file to the equivalent FortiOS settings for a managed switch." Reference: FortiSwitch 7.2 Study Guide, page 349

Tail-drop mode is a congestion management technique used in network devices, including FortiSwitches, to handle congestion on network ports:
Tail-Drop Mode (A):
Behavior: When a queue reaches its maximum capacity on a congested port, tail-drop mode simply drops any incoming packets that arrive after the buffer is full. This continues until the congestion is alleviated and there is space in the queue to accommodate new packets.
Application: This is a straightforward approach used when the device's buffer allocated to the port becomes full due to sustained high traffic, preventing buffer overflow and maintaining system stability.

The MAC address "00:50:56:96:e3:fc" appearing in two different VLANs (4089 and 4094) in the diagnostic output indicates it is a MAC address associated with a device that supports traffic from multiple VLANs. Such a behavior is typical of network infrastructure devices like switches or routers, which are configured to allow traffic from various VLANs to pass through a single physical or logical interface. This is essential in network designs that utilize VLANs to segregate network traffic for different departments or use cases while using the same physical infrastructure.

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.
