ASA Active/Passive Failed

Michael Wollner — Mon, 11 Mar 2019 22:13:47 GMT

Hello,

i have a problem with a Failover Pair of 5510. The Boxes run with the software version 8.2.5.

If the Active ASA goes down, the Standby ASA switch to Active.

Now the problem.

If i switch on the old Active ASA, both ASA are Active.

This problem don't solved with the command 'no failover active' on the Standby box.

This problem only solved with the command 'no failover' and then 'failover' on the Standby box.

ASA Active/Passive Failed

use the failover active command on the standby unit or the no failover active command on the active. This should work fine if not working then something else might causing some issue.

Hello ajay,

This command have no effect on the Standby unit. Both ASA Primary and Standby are Active after restart the Primary ASA.

Only the command 'no failover' and then 'failover' works.

Hi Michael,

Can you post failover config for both the Firewalls as well as show failover output attached with them?

Thanks

Ajay

The Standby ASA is now Offline. I can't get a 'show failover' now. I post the logging at Monday.
