What is swL2MACNotifyHistorySize?
Sets how many MAC address table change events the switch buffers in its internal history log before older entries are overwritten (1-500, default 1). Increasing it lets an admin review a longer backlog of learn/age events after enabling MAC notification, rather than only the most recent change.
