Cisco ASA 5510 Failover.

[antrikos_kal]

Hello there,

How failover works on ASA 5510?In PIXes it had a failover cable.If I have 2xCisco 5510 w/ security plus LICENSES and both active/active the failover feature, how do I connect (physically) those two units?

Thanks,

-Andrew.

In ASA-Failover, both devices are connected with a free Ethernet-port:

But I would not spend any more effort into an 5510. This device is EOL and does not get any more security-updates. You should not connect it to an insecure network like the internet.
