In a Cisco firewall log, the %ASA-1-106021 part represents a Mnemonic message. %ASA refers to the Cisco Adaptive Security Appliance, 1 denotes the severity level, and 106021 is the specific code for the log message. This code helps in identifying the nature of the logged event or action.
In Cisco firewall logs, the %ASA-1-106021 part of the log entry is a Mnemonic message. Here's the breakdown: %ASA: Indicates the type of device, which in this case is a Cisco ASA (Adaptive Security Appliance) firewall. 1: Denotes the severity level of the message (1 is for emergencies). 106021: This is the specific log message code that corresponds to a predefined event or action in the firewall. So, %ASA-1-106021 represents a specific message type or mnemonic that details the nature of the event or action being logged.
