ASA Lan & statful failover on subinterfaces

Unanswered Question
Jul 28th, 2008


Has anyone of you guys configured Lan & stateful failover interface on a single physical interface with two subinterfaces dedicated for each?

I am configuring 5520's in an Active/Standby mode and falling short on the physical interfaces...

Pls advise or refer any cisco documentation regarding the same.


I have this problem too.

what do you mean "falling short on the physical interfaces"?

Just make sure you've used standby IP's on any interface with a regular IP.

You dont need to make any sub-interfaces. Just use the same 'physical' interface for both failover and stateful links. It works as long as your state traffic does not overwhelm the bandwidth of the interface.
