ubiSldNotifyOnlyEnbaled is a read-write TruthValue that globally enables sending only a notification when a self-loop is detected, without actually disabling the affected interface. Admins enable this when they want visibility into loop events without the disruption of ports being automatically shut down, useful in environments where automatic port shutdown would be too aggressive. For example, an admin in a lab environment with frequent intentional loopback testing might set this to true so SLD only logs/traps the event rather than disabling ports each time.
