The Cisco® Advanced Services Deploy, Maintain, and Troubleshoot Cisco IOS® XR Software (DMTXR) Version 3.0 instructor-led course offered by Cisco High-Touch Delivery Learning Services provides you with the advanced knowledge and skill sets required to successfully deploy, maintain, and troubleshoot Cisco IOS XR Software in a typical network environment. You will learn the fundamental concepts on which the operating system is based to understand how to troubleshoot problems relating to process failures, frozen processes, high CPU and memory consumption, and interprocess communication (IPC). You will learn to interpret log messages and configure exception reporting and logging. Emergency recovery procedures for operating system recovery, Cisco CRS-1 system recovery, Cisco XR 12000 Series Router system recovery, and Cisco IOS XR Software configuration and password recovery are covered. In addition, you will use system commands to monitor interfaces, controllers, and application-specific integrated circuits (ASICs) while troubleshooting traffic flow issues through both the Cisco CRS-1 Carrier Router and the XR 12000 Series Routers.

This course combines lecture materials and hands-on labs throughout to make sure that you are able to successfully deploy, maintain, and troubleshoot Cisco IOS XR Software on the Cisco CRS-1 Carrier Router and XR 12000 Series Routers in your network.

Upon completing this course, the learner will be able to meet these overall objectives:

• After completing this course, you should be able to:
• Describe the function of the system database and configuration manager
• Configure and monitor a Terminal Access Controller Access Control System+ (TACACS+) Authentication Authorization and Accounting (AAA) configuration on Cisco IOS XR Software
