Does the ASA's failover interface work at 1000/Full Duplex?

Unanswered Question

I was once told that the speed had to be set to 100Mbs on the Failover link when using LAN based failover on a Gig switchport.

I have this problem too.

I am not aware of any such restriction and the recommendation from Cisco is to use an interface that is running at the same speed as your data interfaces for failover. Are you proposing to use stateful failover ?

I am running Active/Passive on my ASAs right now, this is the only configuration that I needed on my primary unit for the FO interface, I never had to set the interface link speed.

interface GigabitEthernet0/3

description LAN/STATE Failover Interface


failover lan unit primary

failover lan interface FOLink GigabitEthernet0/3

failover replication http

failover link FOLink GigabitEthernet0/3

failover interface ip FOLink standby
