This 4-day course, Introduction to Cisco IOS® XR (IOSXR100), is an instructor led, lab-based, hands-on course, where you learn the fundamental concepts on which the operating system is based and Cisco IOS XR basic operations for configuration, software, file system configuration, and monitoring. Basic troubleshooting for how to troubleshoot problems relating to process failures, frozen processes, and high CPU and memory consumption is also covered.
This course introduces you to the features and functions of the Cisco IOS XR Software operating system. Through a combination of lecture and hands-on lab exercises, you gain an understanding of all major aspects of the operating system, including the architecture, high-availability components, scalability features, configuration basics, switch fabric data path, basic software operations, configuration file overview, monitoring the Cisco IOS XR operating system, and working with error messages and core dumps.
