Configuring System Message Logging Chapter 23 Configuring System Message Logging Disabling and Enabling 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: Step 1 Step 2 Step 3 Step 4 Step 5 Command configure terminal no logging on end show running-config or show logging copy running-config startup-config Purpose Enter global configuration mode. Disable message logging. Return to privileged EXEC mode. Verify your entries. (Optional) Save your entries in the configuration file. 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 "Synchronizing Log Messages" section on page 23-6. To re-enable message logging after it has been disabled, use the logging on global configuration command. Setting the Message Display Destination Device If message logging is enabled, you can send messages to specific locations in addition to the console. Beginning in privileged EXEC mode, use one or more of the following commands to specify the locations that receive messages: Step 1 Step 2 Command configure terminal logging buffered [size] Purpose Enter global configuration mode. Log messages to an internal buffer. The default buffer size is 4096. The range is 4096 to 4294967295 bytes. Note Do not make the buffer size too large because the switch could run out of memory for other tasks. Use the show memory privileged EXEC command to view the free processor memory on the switch; however, this value is the maximum available, and the buffer size should not be set to this amount. 23-4 Catalyst 2950 Desktop Switch Software Configuration Guide 78-14982-01
