Information About Configuring System Message Logs
System Messsage Logging
By default, a switch sends the output from system messages and debug privileged EXEC commands to a
logging process. . The logging process controls the distribution of logging messages to various destinations,
such as the logging buffer, terminal lines, or a UNIX syslog server, depending on your configuration. The
process also sends messages to the console.
When the logging process is disabled, messages are sent only to the console. The messages are sent as they
are generated, so message and debug output are interspersed with prompts or output from other commands.
Messages appear on the active consoles after the process that generated them has finished.
You can set the severity level of the messages to control the type of messages displayed on the consoles and
each of the destinations. You can time-stamp log messages or set the syslog source address to enhance real-time
debugging and management. For information on possible messages, see the system message guide for this
release.
