What is sfddiDownstreamNbr?

This read-only OCTET STRING holds the MAC address of the station immediately downstream of this FDDI port on the ring. Admins use this to map out ring topology and quickly identify which neighboring device is next in line, useful when isolating a break or fault location. If sfddiDownstreamNbr suddenly changes or shows an unexpected address, that signals the ring topology has changed, perhaps due to a station dropping off.
