This is an extension of the FDB table feature request that is marked as complete. In that request, it was discussed about adding a “Last seen” and/or “First Discovered” date to the FDB information to help track MAC addresses over time; however, that part was never implemented.
It would be very useful to have this information in Librenms as it would allow us to centralize more of our monitoring and replace another product we are using for this purpose (NetDB http://netdbtracking.sourceforge.net/)
- Configurable retention time (30 day default?)
- Faster polling (iirc FDB info is part of the discovery process not polling)
