we have purchased these two Cisco ASA 5500 series ASA for a customer who has requested active/standby failover. I have gone through these Cisco documentation explaning the failover configuration and the fact that there are twp methods, statfull and regular.
I am confused about the "Serial Cable" and Also the LAN based failover since there is a switch between the two ASAs for LAN based failover.
these ASA has 4 ethernet ports, 0 through 3 a total of 4. I assume just like PIXs, ethernet 0 is inside interface and ethernet 1 is outside but I am not sure how to use the other two ports(interfaces) for faulover?
what is the serial cable for this type of failover ? and what is the port on teh appliance for this to hapen? I have not seen serlial ports in the back of these appliances?
can someone please help me uderstand this and wht i need t make this happen using the two ASA appliances that the have purchased?
I don't even kno wif thry are the right ones for this job but I know they got the unrestricted license to support failover?
how do I use these 4 ethernet Interfaces?
there are aslo console and managemnet Interfaces as well plus some USB ports, 2 of them.
