I have two 520 PIX running in failover mode on 5.3.3 version. I am getting a message on Primary such as "(Secondary) Lost Failover communications with mate on interface X" and then if I do show failover, it says that its doing testing on both interfaces 0 and 1 of secondary. Output of show failover command is like this:
show failover
Failover On
Cable status: Normal
Reconnect timeout 0:00:00
Poll frequency 15 seconds
This host: Secondary - Active
Active time: 12660 (sec)
Interface outside (x.x.x.x): Normal
Interface inside (x.x.x.x): Normal
Other host: Primary - Standby
Active time: 0 (sec)
Interface outside (x.x.x.x): Testing
Interface inside (x.x.x.x): Testing
When I go to secondary and do show failover, it gives me normal status on all interfaces for itself and primary. Plus on both it says that cable status is normal. I tried by making the secondary to primary but same thing happened. I am getting jerks in connectivity on LAN to internet as primary doesn’t respond on LAN for few seconds and then come back up. This happened in both scenarios when I switched secondary to primary.
A week back, we had power shut down and we kept the primary firewall running while the secondary was shutdown for an hour. If this has something to do with this issue?? if yes then what would be the remedy?
Please if anyone can tell me to how to trouble shoot this issue. Thanks in advance.
