IOSXR100: Introduction to Cisco IOS XR (IOSXR100)

The Introduction to Cisco IOS XR (IOSXR100) v1.0 course introduces you to the features and functions of the Cisco®Internetwork Operating System (IOS) XR Software operating system. You will learn the fundamental concepts on which the Cisco IOS® XR operating system is based, and basic operations for configuration, software, file system configuration, and monitoring. You will learn how to troubleshoot basic issues relating to process failures, frozen processes, and high CPU and memory consumption.

Through a combination of lecture and hands-on lab exercises, you will also gain an understanding of all major aspects of the IOS XR operating system, including the architecture, high-availability components, scalability features, switch fabric data path, basic software operations, configuration file overview, and working with error messages and core dumps.
