ASA Random Failovers

‎01-25-2018 07:04 AM - edited ‎02-21-2020 07:12 AM

Hello I'm working on a ASA 5512 ver 9.4(1) that keeps failing over randomly like once every other week.

When the failed firewall is reboot, it comes back like normal. Can you please assist? Last I did was to disable the service-card monitoring and this is still happening. 

here's the last messages from the show failover history:

Hi

Can you share your config and the output of show failover?
Here it says that you got ifc failure on inside.

Thanks

Here's the config. I checked the inside interface on the switch side and the firewall and they both look good. When we reboot the failed firewall this ifc failure goes away.

It's not able to see the primary unit interfaces.
How the standby interface is connected? Through a vlan or direct cable?

If you use a vlan can you validate full connectivity between them?

Can you share config of primary asa?

Thanks

This output says that failover is passing through g0/5 but behind the hood, is it a direct cable or is there a switch or multiple switch transporting a vlan?

 

The 2nd asa is in failed status and interfaces attached to it are in unknown state.

Can you validate the physical or logical path between them?

 


Thanks

Nothing wrong on this output.

You said when you reboot everything is back normal? 

Can you reboot the standby and paste the show failover again?

 

Do you see something on logs?
