using the management interface as the failover interface

Unanswered Question
May 21st, 2010

cisco does not recommend the use of management interface for failover.  one reason is the management interface is not Gigabit but a 100mbps link.  i monitor the traffic load on the ASA using MRTG. if my OUTSIDE, public facing, interface has a YEARLY average of 1.3 mbps, and a YEARLY peak of 86 mbps, does that mean i can use the management interface for failover without much problems?

I have this problem too.

It all depends on connection rates rather than amount of traffic. The more connection replication, the more traffic for the failover link, the more load for the failover link.

from the numbers you are giving though, I believe the ASA would be able to handle it.

I hope it helps.

You can use it without any issues , as only TCP states will be updated via failover link, you can goahead and use.
