course contents :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
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.For more information, please visit www.cisco.com/go/ase.
After completing this course, the learner will be able to meet these overall objectives:
● Describe the function of the system database (Sysdb) and Configuration Manager
● Configure and monitor a TACACS+ AAA configuration on Cisco IOS XR Software
● Explain the architecture of the Cisco IOS XR Software operating system and the commands to monitor its operation.
The course outline is as follows:
● Module 1: Configuration ManagementProvides an overview of configuration management in Cisco IOS XR Software and the function of the Sysdb service. It explains how data moves between the Sysdb and line cards. The module explains the use of the binary configuration and examines the binary files in the commitdb directories.
● Module 2: AAA SecurityExplains AAA security and the AAA security functions. It defines task-based authorization using task groups and user groups and explains how to configure task-based security and user security policies in Cisco IOS XR Software. The module explains the role of Management Plane Protection and how to implement it. You also create a TACACS+ AAA configuration on the router, and you create user and router policies on the TACACS+ server. The module also reviews the CLI commands you can use to monitor and troubleshoot AAA security operations.
● Module 3: Monitoring the Cisco IOS XR Software Operating SystemExplains the architecture of the Cisco IOS XR Software operating system. It describes both the logical and physical architecture and the major components of the operating system. This module also introduces the commands used to monitor the Cisco IOS XR Software system.
● Module 4: Monitoring ProcessesDescribes the mandatory processes in Cisco IOS XR Software. It explains how to identify and locate abnormal memory usage and how to monitor system performance. The module describes how to monitor problems relating to process failures, stuck processes, and high CPU consumption processes. It also identifies the types of information to capture before contacting Cisco Technical Support.
● Module 5: Interprocess CommunicationDescribes how IPC occurs in Cisco IOS XR Software. It explains the ways in which processes perform message passing, and it describes the methods and mechanics of IPC.
Who Should Attend
This course is intended for network professionals (including designers, implementers), network operations center (NOC) personnel, and support staff, who are involved with the deployment, operations, maintenance, and troubleshooting of Cisco routers that run the Cisco IOS XR Software operating system.
