For this configuration I'm going to use GNS3 with QEMU emulator to run a ASA in a virtual environment.
First get the files downloaded
GNS3 : https://www.gns3.com/
ASA Images :
ASA842-Intrid and ASA842vmlinuz
I'm not going to describe how to set the ASA in GNS3
For failover configuration
Node 01 :
(config)#failover lan unit primary
(config)#failover lan interface FOLINK Gi0/0
(config)#failover interface ip FOLINK 10.1.1.1 255.255.255.0 standby 10.1.1.2
(config)#failover
Node 02 :
(config)#failover lan unit secondary
(config)#failover lan interface FOLINK Gi0/0
(config)#failover interface ip FOLINK 10.1.1.1 255.255.255.0 standby 10.1.1.2
(config)#failover
P.S : You may also configure link failover (state failover) with the command
Node 01 & 02:
(config)#failover link FOLINK Gi0/1
Verification Commands,
#show failover
#show failover state
