The following is for working with the Cisco ASA with failover – where you have two ASA’s set up so that one will take over when one fails. This is not used for ISP failover. For that, see here.

Force failover ASA’s to change which one is currently active

myasa# failover exec standby failover active

See which ASA is the active in a failover group

 myasa# show failover | grep host
    This host: Secondary - Active 
    Other host: Primary - Standby Ready
