Configuring System Message Logging
Default System Message Logging Configuration
Table 30-2 shows the 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.
Disabling the logging process can slow down the switch because a process must wait until the messages
are written to the console before continuing. When the logging process is disabled, messages appear on
the console as soon as they are produced, often appearing in the middle of command output.
