User Guidelines
The logging process controls the distribution of logging messages to the various destinations, such as
the logging buffer, logging file, or syslog server. Logging on and off for these destinations can be
individually configured using the logging buffered, logging file, and logging global configuration
commands. However, if the logging on command is disabled, no messages are sent to these
destinations. Only the console receives messages.
Example
The following example shows how logging is enabled.
Console (config)# logging on
5.24.2 logging
