Limitations of FDM

[vetriselvan]

We are planning to operate the 3105 FTD firewall without FMC.

Is it possible to use FDM without FMC?

If so, what are the limitations of FDM?

sure you can use FDM without FMC, in real if you use both then each one will erase the config done by other.

That 2017 slide is a bit outdated. You can now do HA, port channels, SSL and Identity polices etc. using FDM.

FMC (on-prem or cloud-delivered) is still recommend for most customers however. You can migrate FDM 7.2+ to FMC later using the Migration Tool. This did not used to be possible.

YES / NO depends on the requirement and environment you managing the (devices)

what are the limitations of FDM?

Many features improved in 7.X  onwards also in 7.3 for FDM (that does not mean it replace 100% FMC).

Chcek what features you looking to use - based on that made decison ( my view FMC or Cloud one is best option).
