System link monitor in 5.6

Hello together,

we upgraded from OS 5.2.5 to 5.6.1. We configured the option system link-monitor on 5.2.5.

After we upgraded the function is disappeared, but it is already in our config file.

Is the function replaced in 5.6.1 ? Is "SD-WAN Status Check" the replacement ?

Many thanks for your help.

regards

Patrick
