ASA 5510 failover


I have 2 ASA 5510 and i want to create failover between them.

The 2 ASAs have the Security Plus license and 3DES enable.

But when I try to create the failover i obtain the following error message "Hardware module compatibility for platform failed"

See the following "show ver" wich confirm the 2 ASA have an identical hardware and fonctionnality.

The only difference is:

Hardware: ASA5510, 256 MB RAM, CPU Pentium 4 Celeron 1600 MHz

Hardware: ASA5510-K8, 256 MB RAM, CPU Pentium 4 Celeron 1600 MHz


Re: ASA 5510 failover

You are probably trying to do that through ASDM, try it via CLI and it should work.

It happened to me. I dont know if it's an ASDM bug.

Re: ASA 5510 failover

I resolve the problem.

One ASA was in mode single and the other in mode multiple.

Re: ASA 5510 failover

Hello mathieuchanu,

I have the same issue.

Did you have done the configuration by CLI or ASDM?
