What is fnSysSerial?

This OID stores the device's unique serial number as a text string, matching the physical label on the hardware. Operationally, it identifies the specific physical unit for warranty, support, and asset tracking purposes. A network operator retrieves this value for RMA (Return Merchandise Authorization) requests, inventory management, or when contacting vendor support.
