The Introduction to Cisco IOS XR (IOSXR100) v1.0 is a 2-day instructor-led course that introduces learners to the fundamental concepts on which the operating system is based, and Cisco IOS XR basic operations for configuration, software, file system configuration, and monitoring. The course also covers basic troubleshooting for how to troubleshoot problems relating to process failures, frozen processes, and high CPU and memory consumption.
The course introduces learners to the features and functions of the Cisco IOS XR Software operating system. Through a combination of lecture and hands-on lab exercises, learners 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.

When delivered online, as a virtual-instructor-led training (VILT), the course duration is extended to 4 days.
