The threshold is measured based on:<br><br>\u2728 Latency ms<br>\ud83e\udd50 Jitter ms<br>\ud83c\udf7f Packet loss %<br><br>You would configure within the Groups of Interest in SD-WAN Manager initially to determine what the threshold should be. So if an application is experiencing 10% packet loss which breaches the threshold , you can configure to fallback to the LTE for just that specific application and drop everything else.
