Re: Detect Non Stable WAN with Link monitor
There might be something different in SD-WAN config to specifically detect packet losses, which I'm not familiar with. But again it would be likely using the same ping mechanism the link-monitor uses.
If the packet loss rate is consistently 40%, the probability is your link-monitor ping packets would be lost 40% as well. In reality those drops don't happen exactly in the same sequence all the time like !!!!!!....!!!!!!....!!!!!!!....(18 successes/12 failures) and so on. But likely something like !!..!!.!!..!!!.!!!!....!!..!!!(18 successes/12 failures).
I think you can adjust the interval shorter from the default 5 sec, and less failtime from the default 5 times to catch those failures to trigger a failover. Most difficult part is you can't test until 40% packet loss ready happens.
