With ASA, the secondary IP is always reachable, just like the primary IP.

Yes. This is normal. You need to configure your interface to have a standby IP. Don’t try to set a different config on the standby unit as it will just be overwritten by the primary.

Set your management interface on the primary like follows:

ip address standby

Your primary unit will be accessible from and your standby ASA will now be accessible from

level 4

It’s easy to confuse primary/secondary with active/standby. Wherever you have primary above, it should say Active. Primary/secondary role stays with the unit it was configured on, whether it is active or standby.

level 3

Did yoy configure the ASA1 is stand by, and ASA2 is active? For the failover change.
