This object identifies which of three lifecycle actions, creation, deletion, or modification, triggered the accompanying notification about an optical patch, a logical or physical cross-connect between optical ports. It matters because on optical transport gear, patches represent actual physical or logical light paths carrying traffic, so knowing whether a notification represents a new patch being stood up versus an existing one being torn down or changed is critical to correctly interpreting whether a resulting service disruption was intentional. A notification arriving with this object set to delete right before a service outage ticket comes in would immediately confirm the outage was caused by a patch removal, deliberate or accidental, rather than an equipment fault.
