process, use the

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 mode commands. However, if the
logging on
command is
disabled, no messages are sent to these destinations. Only the console receives messages.
