ASA Redundant Interface Failover

[Cody Ridge]

Hello,

I have two ASA 5540s, ver 8.4 configured in Active/Standby failover.

I am also using the redundant interface feature for my Inside interface.  Gig0/0 is the active primary and Gig0/1 is standby.

I will activate failover monitoring of the Inside interface using the monitor inside command.

My question concerns the failover monitoring of the redundant interface.  If the gig0/0 connection were to fail would the Gig0/1 interface become Active, AND simultaneously result in a full device failover?

Or, does Gig0/1 of the Inside interface redundant pair simply become active and not change the Inside interface device failover state?  Thus NOT resulting in a device failover.

Regards,

"When  the active interface fails over to the standby interface, this activity  does not cause the redundant interface to appear to be failed when  being monitored for device-level failover. Only when both physical  interfaces fail does the redundant interface appear to be failed."
