Explanation:

https://www.cisco.com/c/en/us/support/docs/security/firepower-management-center/212699-configure-ftd-high-availability-on-firep.htmlConditionsIn order to create an HA between 2 FTD devices, these conditions must be met:

Same model

Same version (this applies to FXOS and to FTD - (major (first number), minor (second number), and maintenance (third number) must be equal)) Same number of interfaces Same type of interfaces Both devices as part of same group/domain in FMC Have identical Network Time Protocol (NTP) configuration Be fully deployed on the FMC without uncommitted changes Be in the same firewall mode: routed or transparent.

Note that this must be checked on both FTD devices and FMC GUI since there have been cases where the FTDs had the same mode, but FMC does not reflect this.

Does not have DHCP/Point-to-Point Protocol over Ethernet (PPPoE) configured in any of the interface Different hostname (Fully Qualified Domain Name (FQDN)) for both chassis. In order to check the chassis hostname navigate to FTD CLI and run this command
