Deploy, Maintain, and Troubleshoot Cisco IOS XR Software

Course details

Overview:

This course provides you with the advanced knowledge and skill sets required to successfully deploy, maintain, and troubleshoot Cisco IOS® XR Software Release 4.0.1 in a typical network environment. You will learn the fundamental concepts on which the operating system is based in order to understand how to troubleshoot problems relating to process crashes, stuck 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 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 ASICs while troubleshooting traffic flow issues through both Cisco CRS-1 and 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 the Cisco IOS XR Software on Cisco CRS-1 and XR 12000 series routers in your network.
