This is the read-only status counterpart to swCFMExtMgmtLockState, reporting whether a lock condition from a lower-level domain is currently detected(1) as active or has been cleared(2), mirroring swCFMExtMgmtAISStatus's role for the AIS function. It is the object confirming whether a planned maintenance lock is actually in effect right now, letting downstream monitoring or the maintenance team itself verify the lock signal is being correctly asserted for the duration of the work. A technician who enabled the lock function before starting maintenance would check this status reads detected(1) to confirm the lock is actually active before proceeding with the disruptive part of the work.
