Hi halijenn / experts
I have a query related to failover and want to know as to what exactly is the advantage of using the switch between the 2 devices . If i am using cross over cable for the failover interfaces , i can understand that if cable is bad or any of the asa failover interface ports is faulty , it may lead to communication failure . Hence what is the advantage of using a switch in place of cross over cables
Nope. Shouldn't be any disruption.
Ankurs, With a switch in the middle, a failure of one interface will not affect the peer's interface (will still stay up). It is advised to use a switch for this reason. In your example, a failure of Fa0/2 will not impact Fa0/3 by design. A switch will have zero impact on config replication performance or any replication of connections etc. - Magnus
