ASA5520 Failover Problem

[justin.dalwood]

Hi Everyone,

I have just installed 2 new ASA5520 devices configured for A/S failover.

Every few hours or so the following is logged and the devices failover:

%ASA-1-104001: (Primary) Switching to ACTIVE - HELLO not heard from mate.

I am using the management interface for both the failover traffic and state information. The memory usage is 75MB and CPU utilisation if 0%.

Can anyone think of why these hello messages are being missed?

Basically these devices seem to function ok but they continually failover.

Thanks

Hey Justin

Have a look at this URL... it clearly gives indications of why failovers are normally triggered:

http://www.cisco.com/en/US/products/ps6120/products_configuration_guide_chapter09186a008045247e.html#wp1046889

failover can occur only when the device/power/interfaces of the primary fails.. there are a couple of commands on the doc given above... try those too...

Hope this helps..

Thanks for the link.

I guess what i am trying to figure out is why the devices keep failing over.

Here is a snippet of its behaviour today:

12-12-2006 07:42:02 %ASA-1-104001: (Primary) Switching to ACTIVE - HELLO not heard from mate.

12-12-2006 07:53:20 %ASA-1-104001: (Secondary) Switching to ACTIVE - HELLO not heard from mate.

12-12-2006 12:24:00 %ASA-1-104001: (Secondary) Switching to ACTIVE - HELLO not heard from mate.

12-12-2006 13:19:21 %ASA-1-104001: (Primary) Switching to ACTIVE - HELLO not heard from mate.

12-12-2006 15:56:23 %ASA-1-104001: (Secondary) Switching to ACTIVE - HELLO not heard from mate.

12-12-2006 16:25:43 %ASA-1-104001: (Primary) Switching to ACTIVE - HELLO not heard from mate.

I don't understand why the hello's are not being heard since the failover interface (management0/0) are connected via a 2m xover cable...
