ubiSldIfNotifyOnlyEnabled is a read-write TruthValue that, when configured, causes a detected self-loop on this interface to trigger only a notification rather than disabling the interface. Admins use this per-port override to exempt specific ports from automatic shutdown when a loop is detected, overriding the global ubiSldNotifyOnlyEnbaled behavior for that port. For example, an admin might enable this on a lab test port that's intentionally looped, so SLD logs the event there without taking the port down.
