FortiGate HA - Would it Failover if an interface remains active but IP connectivity is lost

[ck8882]

HI All,

May i know would it FortiGate Failover if an interface remains active but IP connectivity is lost? If yes, is it enable by default once configure HA? If no, is there any additional configuration to achieve it, like IP SLA in cisco HSRP?

Thanks

HI @ck8882 ,

I believe you are referring to the link monitoring not to the physical interface. 
If Yes, Have a look here as it may help :

Another option is with HA heartbeat.

 If that is the case here is how to configure it:

Hi @ck8882.,

You can use link-monitor for this purposes. Please refer to the following documents:
