I have two ASAv firewalls setup in CML 2.2 for Active/Standby Failover. The firewalls sync no problem and I can manually failover between the firewalls using the "failover active" command. The firewalls don't failover automatically, however. For instance, if I delete the link on the outside interface of the active firewall, it stays active.
Is this supported in CML? Perhaps it doesn't work due to the CML quirk where interfaces stay "up" all the time, even if there is no link to the interface.
