Hi,

is there a way to display and/or log received spanning-tree topology change notifications?
TCNs are causing switches having to flush the mac address table, which may cause painful jitter within larger layer2 networks.

This information should be added to the switch log if STP et. al. is enabled, to allow debugging and mitigation.

Any hint on this one? Terminal command for debugging would be also ok.

Once again I am trying to bump this topic after no response from Netonix for >1y.
Is there a way to log or debug spanning-tree TC notifications and determine the source port causing this issue?
