What is ctDiscoveryNMPort?
This integer gives the port index on which this MAC/Network association was most recently observed, with a value of zero indicating the port could not be determined. Combined with ctDiscoveryNMBoard, it lets an admin pinpoint the exact physical port a discovered host is plugged into for cable-tracing or troubleshooting. For example, an admin chasing down an unauthorized device found via discovery can read ctDiscoveryNMPort to learn it's plugged into port 12, then go disconnect that cable.
