However, clearly, it would be useful to keep a copy of the log messages for later review, so IOS provides two primary means to keep a copy. IOS can store copies of the log messages in RAM by virtue of the logging buffered global configuration command. Then any user can come back later and see the old log messages by using the show logging EXEC command. As a second option—an option used frequently in production networks—all devices store their log messages centrally to a syslog server. RFC 5424 defines the Syslog protocol, which provides the means by which a device like a switch or router can use a UDP protocol to send messages to a syslog server for storage. All devices can send their log messages to the server. Later, a user can connect to the server (typically with a graphical user interface) and browse the log messages from various devices. To configure a router or switch to send log messages to a syslog server, add the logging {address\|hostname} global command, referencing the IP address or hostname of the syslog server. Figure 33-2 shows the ideas behind the buffered logging and syslog logging.”” [Wendell Odom](https://sms4smile.com/quotes/author/wendell-odom/) ## About This Quote This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation. Explains two methods for preserving log messages: buffered RAM storage and remote syslog server, enabling later review. **In simple terms:** How to keep logs for future analysis. Key Takeaway Use buffering or syslog to retain logs. Themes network management logging system administration troubleshooting Mood practical technical informative Type instructional reference When to use this quote - router configuration - network monitoring - incident response - audit trails Key Concepts buffered logging syslog protocol RFC 5424 remote storage Questions to Reflect On - How do you decide between local buffering and remote syslog? - What security concerns arise with central log storage? A Different Perspective Requires sufficient storage and network bandwidth; remote logging may introduce latency. ★ ★ ★ ★ ★ No ratings yet [Messages Syslog](https://sms4smile.com/quotes/about/messages-syslog-561000/) [Storing Log](https://sms4smile.com/quotes/about/storing-log-560999/) [Syslog Logging](https://sms4smile.com/quotes/about/syslog-logging-561002/) [Syslog Protocol](https://sms4smile.com/quotes/about/syslog-protocol-560998/) [Syslog Server](https://sms4smile.com/quotes/about/syslog-server-561001/) [User interface](https://sms4smile.com/quotes/about/user-interface/) ## Related quotes > [“Storing Log Messages for Later Review With logging to the console and to terminals, an event happens, IOS sends the messages to the console…](https://sms4smile.com/quotes/wendell-odom/storing-log-messages-for-later-review-with-logging-to-the-console-and/) [Wendell Odom](https://sms4smile.com/quotes/author/wendell-odom/) > [“First, note that the example configures the same message level at the console and for terminal monitoring (level 7, or debug), and the same…](https://sms4smile.com/quotes/wendell-odom/first-note-that-the-example-configures-the-same-message-level-at-the/) [Wendell Odom](https://sms4smile.com/quotes/author/wendell-odom/) > [“Configuring and Verifying System Logging With the information in Table 33-2, configuring syslog in a Cisco IOS router or switch should be relatively straightforward.…](https://sms4smile.com/quotes/wendell-odom/configuring-and-verifying-system-logging-with-the-information-in/) [Wendell Odom](https://sms4smile.com/quotes/author/wendell-odom/) > [The user interface on the iPhone, with all due respect for what this invention was all about is now five years old.](https://sms4smile.com/quotes/thorsten-heins/the-user-interface-on-the-iphone-with-all-due-respect-for-what-this/) [Thorsten Heins](https://sms4smile.com/quotes/author/thorsten-heins/) > [History repeats itself again I guess the rate of innovation is so high in our industry that if you don’t innovate at that speed…](https://sms4smile.com/quotes/thorsten-heins/history-repeats-itself-again-i-guess-the-rate-of-innovation-is-so/) [Thorsten Heins](https://sms4smile.com/quotes/author/thorsten-heins/) > [The act of voting, to put it in computing terms, is a question of user interface.](https://sms4smile.com/quotes/ellen-ullman/the-act-of-voting-to-put-it-in-computing-terms-is-a-question-of-user/) [Ellen Ullman](https://sms4smile.com/quotes/author/ellen-ullman/) > [Perhaps the most versatile and useful plug-in in the collection is Mass Copy.
