Cisco ASA Audit Event: 210003

Cisco ASA Events

The logs of network perimeter devices such as firewalls, antivirus applications and intrusion prevention systems contain crucial information that helps to pre-emptively block security attacks and breaches. Hence, it's mandatory for you to monitor and audit these logs. Because Cisco ASA provides the combined functionality of all the three, it becomes all the more important to monitor its logs. 

ManageEngine's EventLog Analyzer, a comprehensive log management solution, collects and analyzes the log data from Cisco ASA devices, triggers alerts and generate reports on detected security incidents thus helping you to take suitable measures against security threats, if any.

210003: Unknown LU object

Cisco ASA is a security device that provides the combined capabilities of a firewall,an antivirus, and an intrusion prevention system. It also facilitates virtual private network (VPN) connections.It helps to detect threats and stop attacks before they spread through the network.

Message: %ASA-3-210003: Unknown LU Object number.

Event 210003 is generated when Stateful Failover receives an unsupported logical update object and is unable to process it. This might have been caused by a corrupted memory, LAN transmissions or other such events.

How could you resolve this situation?

If this even keeps recurring, check the Stateful Failover link LAN connection. If the error had not caused by a faulty failover link LAN connection, determine if an external user is trying to compromise the protected network. Also, check for misconfigured clients.
