Configure Active-Standby High Availability on a ASA

Jason Tramer Jason Tramer Profile: Jason Tramer

Ok so you can easily do this from within the ASDM using the HA wizard, however I recently tried this and had issues with the wizard not working for me. So here is how you do it from the cli:
Primary:

failover
failover lan unit primary
failover lan interface failover Ethernet X
failover key cisco
failover interface ip failover x.x.x.1 y.y.y.y standby x.x.x.2

Secondary:
failover
failover lan unit secondary
failover lan interface failover Ethernet X
failover key cisco
failover interface ip failover x.x.x.1 y.y.y.y standby x.x.x.2
It should begin the failover replication process immediately upon completing both units.

Use “show failover” to see the status

Hope this helps

    Jason, this was a life-saver! We were trying to setup an ASA 5505 for high availability failover and we could NOT get the wizard to work - it kept failing on Step 3 whenever we hit the "Next" button. We had all but given up on the GUI (and the setup) when I found your post and voila! We entered the commands and it worked like a charm. Thanks again!
