the switch operates.
Understanding System Message 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.
The syslog format is compatible with 4.3 BSD UNIX.
Note
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 console 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.
