This post shows a basic configuration step for a HA setup of two Firepower 1010. 

FDM is a web-based, simplified, on-device manager. Because it is simplified, some FTD features are not supported using FDM. You should use FDM if you are only managing a small number of devices and don’t need a multi-device manager. Note Both FDM and CDO can discover the configuration on the firewall, so you can use FDM and CDO to manage the same firewall. FMC is not compatible with other managers

  • Firepower Threat Defense(FTD)
  • Firepower Device Manager (FDM)
  • Firepower Management Center (FMC)
  • Cisco Defense Orchestrator (CDO)

HA System Requirements

The 2 units in the HA must:

  • Be the same model
  • Have the same number and types of interfaces
  • Be in the same firewall mode (routed or transparent)
  • Have the same software version
  • Be in the same domain or group on the FMC
  • Have the same NTP configuration
  • Be fully deployed on the FMC with no uncommitted changes
  • Not have DHCP or PPPoE configuration in any of their interfaces
  • FTD devices in HA mush have the same license
  • HA configurations require two smart license entitlements; one for each device in the pair.
