ASA context licensing in Act/Stby

[#1]

Customer has two units of ASA5585-X with base license which each contains 2 security contexts; 4 total contexts per pair.
They’re looking at deploying active/standby failover and configuring 4 different context on the active box.

How many contexts to be licensed in this case?
4 (only contexts on the active box are counted)?
or 8 (context on the standby box are also counted)?

Thanks in advance!

In an HA pair the contexts combine - so you have 4 to work with (absent having added any optional context licenses).

When counting against the license limits, only count the configured contexts (and the system context doesn't count).

So in your example, the customer requires 4 contexts - which is what they have.
