HA interfaces for Heartbeat

[BensonLEI]

Hi, guys,

We have Fortigate 400e HA pairs, and the HA cables (two cables for HA ) are connected directly (i.e Forti400e -UTP cable- Forti400e). May I know if these two cables could be Lacp ?

Also what are optimal values of the configurable setup for HA synchronization ?

Many thanks

No, you should absolutely not use aggregate interfaces for HA.  See Fortinet's HA best practices here:

Hi, Lobstercreed,

Thanks for the weblink, I think this page might be more precisely describing the HA heartbeat interface and its configuration.
