Description: This object identifies this MAC's previous downstream neighbor.
What is cntFddiMACOldDownstreamNbr?
This object identifies this MAC's previous downstream neighbor before the current one. An administrator compares this against cntFddiMACDownstreamNbr to see exactly which neighbor relationship changed and confirm a suspected ring reconfiguration event. For example, if the old and current downstream neighbor values differ, the admin has direct evidence that a station was added, removed, or reordered on this segment of the ring.
