Default System Message Logging Configuration
Disabling Message Logging
Message logging is enabled by default. It must be enabled to send messages to any destination other than
the console. When enabled, log messages are sent to a logging process, which logs messages to
designated locations asynchronously to the processes that generated the messages.
Beginning in privileged EXEC mode, follow these steps to disable message logging. This procedure is
optional.
