As title, the idea from @flottmedia , Nebula Switch should have event logs when the ports change the state from forwarding to blocking.

In general it would be helpful to have more detailled information on certain events. E.g. "STP topology changes" could also display an added / changed / removed MAC and Port or "Port X - PortX link down" also the MAC, IP, name of the device in the log details similar to the detail field of some NAP log entries.
