Probing provides information about the quality of an internet connection and what action to
take if there is no connectivity. You can configure separate probing settings for each
internet connection.
To configure probing for an internet connection (pings):
1. In the Internet Connectivity page, select a connection and click Connection
Monitoring.
The Edit Internet Connection window opens.
2. In the Connection Monitoring tab, select Monitor connection state by sending probe
packets to one or more servers on the Internet.
Select this option to use more methods and servers to detect connectivity loss.
Important - In versions R81.10.10 and higher, it is supported to disable
probing in an Internet connection only if you clear the option, "This Internet
connection will be a part of SD-WAN" (on the "Advanced" tab > section "SD-
WAN Settings").
3. For Connection probing method, select ping addresses.
4. Under Advanced Probing Settings, use the default values or enter new ones for:
n
Recovery time (in seconds)
n
Max latency allowed (milliseconds)
n
Probing frequency (seconds)
n
Window size (pings)
n
Failover pings (percent failures)
5. Click Apply.
