Cisco ASA Audit Event: 105020

105020: Incomplete / slow configuration replication

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-1-105020: (Primary) Incomplete/slow config replication.

Event 105020 is generated when a failover occurs and the Active ASA detects a partial configuration in memory. This is usually caused by an interruption in the replication service.

How could you resolve this situation?

After the ASA detects the failover, it automatically reboots and loads the configuration from flash memory and/or resynchronizes with another ASA. If failovers occurs repeatedly, check the failover configuration and make sure that both ASAs can communicate with each other.
