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.
To disable message logging, perform this task:
Command
Step 1
Switch# configure terminal
Step 2
Switch(config)# no logging on
Step 3
Switch(config)# end
Step 4
Switch# show running-config
or
show logging
Step 5
Switch# copy running-config
startup-config
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 are
displayed on the console as soon as they are produced, often appearing in the middle of command output.
The logging synchronous global configuration command also affects the display of messages to the
console. When this command is enabled, messages appear only after you press Return. For more
information, see the
To reenable message logging after it has been disabled, use the logging on global configuration
command.
