In Cisco ASA Active/Standby State-full Failover, what is the difference B/W Failover LAN link and Statefull Failover link.

I understood how to configure.also we can use both LAN & STATE link as a single Interface, for best practice use as separate interface.

interface GigabitEthernet0/6
description STATE Failover Interface

interface GigabitEthernet0/7
description LAN Failover Interface

failover lan interface folink GigabitEthernet0/7
failover link statelink GigabitEthernet0/6
failover interface ip folink 172.16.0.6 255.255.255.252 standby 172.16.0.5
failover interface ip statelink 172.16.0.10 255.255.255.252 standby 172.16.0.9

The failover link is used for hellos between the firewalls, to replicate and synchronise the configuration, to exchange information about interfaces eg mac addresses and link status and which one is active and which one is standby.

The state failover link is used to pass the state table across so that existing connections can be preserved if the firewalls have to failover.
