In this article we will discuss Default Logging, will make brief discussion on Default Logging, In last article we discuss about Service Timestamp.
By default, Cisco routers and switches send log messages for all severity levels to the console. On some IOS versions, the device also buffers log messages by default.
The show logging command displays the default logging service settings on a Cisco router. The first lines of output list information about the logging process, with the end of the output listing log messages. To enable these two settings, use the logging console and logging buffered global configuration commands, respectively.
The first highlighted line states that this router logs to the console and includes debug messages. This actually means that all debug level messages, as well as any lower level messages (such as notification level messages), are logged to the console. On most Cisco IOS routers, the default severity level is 7, debugging. The output also notes that 32 such messages have been logged.
The second highlighted line states that this router logs to an internal buffer. Because this router has enabled logging to an internal buffer, the show logging command also lists the messages in that buffer. You can view some of the system messages that have been logged at the end of the output.
