Hope someone can help me in this issue, today I spent several hours in it but I wasn't be able to fix it.
Two ASA 5510 appliances configured for failover through management interface. At the beginning, both were connected to a switch with 2 sub-interfaces in each one, one VLAN for sinchro and the other one for stateful.
As it didn't work I connected both ASA directly configuring only the monitoring interface. I have ping between them, both interfaces are up and I removed the command "management-only" from management. Both have the same license, model, version but always have the same error:
Failover LAN Interface: controlasa Management0/0 (Failed - No Switchover)
Attach the output from the next commands from both ASA:
With both interfaces I mean the management interfaces in the appliances.
Yes, they have 4 interfaces, the primary has all of them connected and up and it's providing connectivity to the customer. The secondary only has connected and up the interface management (connected to the another ASA). I didn't connect the regular interfaces because the failover is not working and I would have duplicity IP's issues
