What is jnxL2aldMacHistTableMaxLength?

The maximum number of entries the MAC change history table (jnxL2aldMacHistoryTable) may hold, default 256, with the oldest entry evicted once full; a value of 0 disables history retention entirely. Lower it on memory-constrained devices, or raise it if you need a longer audit trail of MAC learn/remove events.
