Can I use the same interface for both the lan failover cable and the state sync'ing?
I currenlty have the following ocnfig, but I really need another interface for a DMZ, so I'd like to consolidate the lan interface and link interface if possible. Would they use the same IP addresses if this scenario is a valid option?
-----
failover lan unit primary
failover lan interface failover GigabitEthernet0/3
failover link FWstate GigabitEthernet0/2
failover interface ip failover 10.2.0.1 255.255.255.0 standby 10.2.0.2
failover interface ip FWstate 10.2.1.1 255.255.255.0 standby 10.2.1.2
Essentially, I'm asking will the following work:
failover lan unit primary
failover lan interface failover GigabitEthernet0/3
failover link FWstate GigabitEthernet0/3
failover interface ip failover 10.2.0.1 255.255.255.0 standby 10.2.0.2
failover interface ip FWstate 10.2.0.1 255.255.255.0 standby 10.2.0.2

It is possible, but do not duplicate failover interface addresing. Use following config:
failover lan unit primary
failover lan interface FAIL GigabitEthernet0/3
failover link FAIL GigabitEthernet0/3
failover interface ip FAIL 10.2.0.1 255.255.255.0 standby 10.2.0.2

Hi
Looking at the docs To use Stateful Failover, you must configure a Stateful Failover link to pass all state information. You have three options for configuring a Stateful Failover link:
â¢You can use a dedicated Ethernet interface for the Stateful Failover link.
â¢If you are using LAN-based failover, you can share the failover link.
â¢You can share a regular data interface, such as the inside interface. However, this option is not recommended.
If you are using a dedicated Ethernet interface for the Stateful Failover link, you can use either a switch or a crossover cable to directly connect the units. If you use a switch, no other hosts or routers should be on this link.
