How many Security Plus license do I need to configure Active/standby on a pair of ASA 5512-x

[izzinwa]

I have a couple of ASA 5512-x (running same ios software v9.8(3)), one of them has the security plus license required to enable HA pair (failover active/standby).

I was of the impression that you only needed one security plus license to enable HA.

But i cannot enable HA on the second one, says it requires a license. 

do i need ot purchase another security plus license for the second 5512-x? How can enable HA on the pair even though i have only one sec+ license

thanks

Hi Eze, 

This should answer your query

You need the license on both ASAs to enable HA. But keep in mind that this ASA is already End-of-Sale and goes End-of-Support in three years.
