Hi,

   I don't have a demo HW box to test it out, but i would say it's not gonna work as it shouldn't be supported via FlexConfig. FlexConfig is used to deploy mostly GUI unsupported features (but can be used also for GUI supported features) directly to the Lina(ASA). This heartbeat is a sort of keepalive mechanism used by FTD (not by Lina) to detect backplane connectivity with the FXOS chassis, so i don't see how you could push these settings via FlexConfig.

Cristian Matei.

Hello Cris,

thanks for your reply..

yes I am completely agree with you and after doing some research, found the below link..

https://www.cisco.com/c/en/us/td/docs/security/asa/asa-command-reference/A-H/cmdref1/a2.html

app-agent heartbeat

To configure the heartbeat message interval for the app-agent (application agent) running on the ASA to check the health of the Firepower chassis, use the app-agent heartbeat command in global configuration mode

Command Modes

The following table shows the modes in which you can enter the command:

Command Mode	Firewall Mode	Security Context
Routed	Transparent	Single	Multiple
Context	System
Global configuration	·         Yes	·         Yes	·         Yes	—	·         Yes

Thus, what I understood it is CLI command and will work only in Global configuration mode, even not in context mode only on system mode....

Thanks for your quick reply..

Appreciated..
