Perhaps you can add an SNMP Traffic sensor. Then add the switch port of interest.

On the sensor settings, set "Connection Status Handling" to "Show down status for all disconnected states".

On your Notification Triggers, Add State Trigger with this condition:

When sensor state is Up for at least x seconds, perform <select notification/email template>

Hope this achieves what you want :)
