Cisco ASA Audit Event: 212011

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.

212011: SNMP engineBoots is set to maximum value

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-3-212011: SNMP engineBoots is set to maximum value.Reason:%s User intervention necessary.

Event 212011 is generated when the device rebooted 214783647 times, which is the maximum allowed value of the engineBoots variable, or an error reading the persistent value from flash memory occurred. The reason string is specified in the message.

How could you resolve this situation?

If the reason is 'device reboots', the administrator must delete all SNMP Version 3 users and add them again to reset the engineBoots variable to 1. All subsequent Version 3 queries will fail until all users have been removed. If the reason is 'error accessing persistent data', the administrator must delete the context-specific file, then delete all SNMP Version users, and add them again to reset the engineBoots variable to 1. All subsequent Version 3 queries will fail until all users have been removed.
