Good morning

I have two Firepower 2140 arriving soon and I have been searching about the differences between the Active/Active and Active/Passive Failover schemes and I haven't found anything yet

I would like to know what are the operational differences of those schemes, like if there are some services available in a certain scheme that won't work in the other.

Stay pending for your answer, thanks a lot.

Unfortunately, FTD2100 today can only do Active/Standby meaning one FTD will be passing traffic at a time while the other wait for failover which is similar to ASA. Only FTD 4100 and 9300 are capable to Active/Active in a form of clustering. 

Cisco now has an HA bundle SKU which gives you a discount on the second license.


Great info. Thank you for sharing.


I'm just trying to configure FTD HA Active/Standby on EVE-NG using FTD6.6, when I reach the part of selecting the failover interface, there is no interface to select, what could be the problem?
