QSFP+ transceiver (A): The QSFP+ (Quad Small Form-factor Pluggable Plus) transceiver is designed to handle 40G data rates and can be used to split a 40G port into multiple 10G connections. This type of transceiver supports such configurations, making it suitable for high-density applications where multiple 10G connections are derived from a single 40G port, thereby maximizing the utilization of the port and the fiber infrastructure.

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.

From the exhibit and the details given about the routes not installed in the FIB:

• These two routes have a higher administrative distance value available to the destination networks (Option A): Administrative distance is a measure used by routers to select the best path when there are two or more different routes to the same destination from two different routing protocols. A higher administrative distance means that the route is considered less trustworthy, thus not selected for the FIB unless the more preferred routes fail.
• These two routes will become primary, if the best routes are removed (Option B): In routing, if the currently installed routes (which are considered the best due to reasons like lower administrative distance) are removed or become unavailable, the next best routes based on administrative distance will be used. This behavior ensures redundancy and maintains network connectivity in diverse scenarios.

References:

• This approach is aligned with standard routing protocol behavior as documented in networking protocols and Fortinet’s routing mechanisms which prioritize routes based on administrative distance and other metrics to maintain efficient and reliable network routing.

VLAN assignments on FortiSwitch ports must follow certain rules and guidelines to ensure network integrity and proper traffic segregation:

• Only Assign One Native VLAN on a Port (C):
• Assign Untagged VLANs Using FortiGate CLI (D):
