Monitor Interfaces for High Availability devices question

Dear All, 

 

       I have 2 x fortigate 201F with HA, port 23 & 24 were connected to each other for HA, may i ask for monitor interfaces which interface i should be added for this ? does it means if i added a interface for example port3, if this port3 were disconnected, the whole devices will be failover to the secondary device ? any help would be appreicated

Hi,

 

- You should be monitoring the interface which are connected and passing the critical traffic in your network. Please refer the below document.

Hi @piaakit1210, 

 

If Monitor interface is down, it will trigger HA failover.
