Edit... Added content. Reference Guide

The ASA supports two failover modes, Active/Active failover and Active/Standby failover. Each failover mode has its own method for determining and performing failover.

• In Active/Standby failover, one unit is the active unit. It passes traffic. The standby unit does not actively pass traffic. When a failover occurs, the active unit fails over to the standby unit, which then becomes active. You can use Active/Standby failover for ASAs in single or multiple context mode.

• In an Active/Active failover configuration, both ASAs can pass network traffic. Active/Active failover is only available to ASAs in multiple context mode. In Active/Active failover, you divide the security contexts on the ASA into 2 failover groups. A failover group is simply a logical group of one or more security contexts. One group is assigned to be active on the primary ASA, and the other group is assigned to be active on the secondary ASA. When a failover occurs, it occurs at the failover group level.

Both failover modes support stateful or stateless failover.

..... More info on context mode and other info below.....

from the Cisco forum

Active/Standby failover works in both single mode or multiple context mode. It provides hot standby and replicates all the stateful information from active to standby firewall.

Active/Active failover only works in multiple context mode. Example: if you have 5 context, you can have 2 active on the primary firewall, and 3 active on the secondary firewall. When primary firewall fails, the 2 context who was active on the primary firewall will failover to the secondary firewall. After failover, the secondary firewall will have 5 active context.

In order to run Active/Active you need to run "multiple contexts". When you enable "multiple mode" you lose certain functionality. Remote access VPN is one of them.

  • Our requirement is configure Active/Standby with stateful failover so we don't drop any single packet, do i need licence for stateful failover? or it is just part of configuration? – Satish Aug 24 '17 at 20:59
  • It is a license. supportforums.cisco.com/t5/firewalling/… – Fixitrod Aug 24 '17 at 21:06
  • I am talking about stateful failover license not context licencing. – Satish Aug 24 '17 at 21:09
  • Both modes support stateful failover. I'll add to my answer. – Fixitrod Aug 24 '17 at 21:13
  • The reference guide at the top of that answer is very helpful. – Fixitrod Aug 24 '17 at 21:21
