I have two ASA 5545 running 9.7(1)4. They are an active/standby pair. Failover on all interfaces is working except for one. I am getting repeated log entries every few seconds for this interface of:
ASA-1-105008: (Primary) Testing Interface "Interface Name"
%ASA-1-105009: (Primary) Testing on interface "Interface Name" Passed
From the Active unit I am able to ping the active interface IP but not the standby IP. From the Standby unit I am not able to ping the active interface unit but I am able to ping the standby IP. I have verified that both the active and standby interfaces are up/up without errors. I also do not see the interface bouncing. Again this is the only interface having this issue. All the other firewall interfaces (8 additional) are stable. Any suggestions?
