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.

References:For more details on congestion management techniques and settings on FortiSwitch, you can refer to the configuration manuals available on:Fortinet Product Documentation

"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

When loop guard is enabled on port1 and port2 configured with the same native VLAN (VLAN 10), there are specific scenarios under which port1 can be shut down due to loop guard operation:

A.port1 was shut down by loop guard protection.Loop guard is a specific feature used in network environments to prevent alternative or redundant loops. When loop guard is active, it can shut down a port if it stops receiving BPDU (Bridge Protocol Data Units) on a port that is expected to receive them, assuming a loop or link failure and putting the port into an inconsistent state to prevent potential loops.

B.STP triggered a loop and applied loop guard protection on port1.If the Spanning Tree Protocol (STP) detects a loop or loss of BPDU transmissions while loop guard is enabled, it will proactively shut down the port to prevent network instability or a broadcast storm. This is an essential function of loop guard within the context of STP, providing additional protection against topology changes that could introduce loops.
