With ASA, you will just be using one of the LAN interface on the ASA for failover, ie: straight through cable.

Ha.. that’s great I thought it needs a special cable for failover. Also I have seen that cable based failover is only available in PIX. Is that true?

Thanks Jennifer..

Hi Varun,

So this kind of configuration is not possible with ASA 5520? Please clear my doubts

Yes, thats right Manish, not with any model of ASA.

Hi Varun,

Can you just confirm that ASA 5520 supports cable based Active/Active Failover.

HI Manesh,

Cisco ASA 5520 does not support cable based failover:


Cable-based failover is available only on the PIX 500 Series Security Appliance.

The PIX do have a special failover cable. it is a special cable that are for this purpose only.

The ASA 5520 does NOT have a special failover cable, instead you (or atleast you should) set aside and use one of the Ethernet interfaces to be used as the special failover lan. = normal RJ45 cabeling rules apply. no special cable needed.

Result in both pix and ASA case will be thesame = stateful failover.

So if the question is do you use a special cable then the answer is no, there is nothing special about the cable for the asa, its a normal RJ45 cable.

in the case of pix it is a special cable.

Can you do Active/Active stateful failover with the ASA ? Yes you can.

Good luck

Cable-Based Active/Active Failover is ONLY supported on PIX 500 series security appliance. To answer your question, no, ASA 5500 series cannot do Cable-Based Active/Active Failover,

When the security appliance is configured for Active/Active stateful failover, you cannot enable IPSec or SSL VPN. These features are unavailable. VPN failover is available for Active/Standby failover configurations only.
