How Log Messages Are Organized

How Log Messages Are Organized
Syslog messages are listed numerically by message code. Each message is followed by a brief
explanation and a recommended action. If several messages share the same explanation and
recommended action, the messages are presented together, followed by the common
explanation and recommended action.
The explanation of each message indicates what kind of event generated the message.
Possible events include the following:
■ Authentication, authorization, and accounting (AAA) events
■ Connection events (for example, connections denied by the PIX configuration or address
translation errors)
■ Failover events reported by one or both units of a failover pair
■ File Transfer Protocol (FTP)/Uniform Resource Locator (URL) events (for example,
successful file transfers or blocked Java applets)
■ Mail Guard/SNMP events
■ Security Appliance management events (for example, configuration events or Telnet
connections to the Security Appliance console port)
■ Routing errors
