• Describe the roles of the intrachassis and interchassis control Ethernet network operations
• Understand the interconnection of the optical array cables from the S13 fabric cards in the LCC and the optical interface modules of the fabric-card chassis (FCC)
• Cable the control Ethernet network using the 22-port Shelf Controller-Gigabit Ethernet (SC-GE) card in the fabric chassis
• Build the fabric plane configuration, including the plane number, optical interface module (OIM) count, and the OIM instance number and location in a Cisco CRS-1 multishelf routing system
• Verify the proper operation of the Gigabit Ethernet control network in a Cisco CRS-1 multishelf routing system
• Perform fabric plane administration tasks, including take a fabric plane in and out of service and verify fabric plane status
• Describe the benefits of core consolidation using nonowner SDRs
• Configure a nonowner SDR and verify its operation
• Define what processes are and how they are used in a Cisco CRS-1 multishelf routing system
• Use CLI commands to perform process management functions
• Troubleshoot data flow issues through the switch fabric
• Troubleshoot control Ethernet issues
• Gather information to send to the Cisco support organization to be used in an effort to resolve problems found in a Cisco CRS-1 multishelf routing system
• Use in-service diagnostic tools

This course introduces you to the Cisco® CRS-1 multishelf routing system. You will learn the important theoretical concepts on which the Cisco CRS-1 multishelf routing system is based as well as gain the practical knowledge and skills to successfully configure, maintain, and troubleshoot the Cisco CRS-1 multishelf routing system in your network. This course provides you with an opportunity to practice the techniques taught in class with four lab exercises. You will learn about hardware that composes a Cisco CRS-1 multishelf routing system, the switch fabric architecture, and the control Ethernet architecture. You will learn how to build the switch fabric configuration using both single-topology and multitopology cabling and how to verify the proper operation of the switch fabric and the control Ethernet network. You will be able to document the cable plan used to implement the fabric array cabling. You will able to create and configure secure domain routers (SDRs) and define what process placement is and how placement polices are used in a Cisco CRS-1 multishelf routing system. You will learn how to troubleshoot the Cisco CRS-1 multishelf switch fabric and control Ethernet issues using command-line interface (CLI) commands. This course combines lecture materials and hands-on labs throughout to make sure that you are able to successfully maintain and troubleshoot the Cisco CRS-1 multishelf routing system in your network.

The course outline is as follows:

• Module 1: Cisco CRS-1 Multishelf Overview This module presents a hardware overview of the major FRUs of the Cisco CRS-1 16-slotLCC and FCC and power architecture for each. Cisco CRS-1 multishelf architecture and terminology are discussed, as well as site planning and installation considerations.
• Module 2: Cisco CRS-1 16-Slot Multishelf Architecture This module presents and discusses the Cisco CRS-1 multishelf architecture and the operational aspects of the designated shelf controller (DSC) running on the active route processor, service processors, fabric operations including data flow, SC-GE card in the fabric chassis, and control Ethernet
• Module 3: Cisco CRS-1 Multishelf Cabling This module reviews the documented Cisco CRS-1 multishelf cabling plan to show the neeto have documented interconnections prior to beginning the configuration of the multishelf fabric and control Ethernet. Students are presented with both single-module and multimodule fabric cabling schemes. In addition, this module discusses the control Ethernet cabling scheme using the 22-port SC-GE controller.
• Module 4: Cisco CRS-1 Multishelf Switch Fabric Configuration This module explains how to verify the version of Cisco IOS® XR Software, ROMMON, MONLIB software, and field programmable device software and upgrade to a newer version when necessary. This module also explains how to configure the rack number and serial number for the LCCs and FCC. It describes how to configure the fabric planes for a 2+1, 2+2, and 2+4 configuration, including; the plane number, the OIM count, and the OIM instance number and location. This module also explains how to verify fabric connectivity.
• Module 5: Cisco CRS-1 SDRs This module provides a high-level overview of the SDR creation and functionality.
• Module 6: Cisco CRS-1 Multishelf Process Placement This module presents the concepts of process placement and process management. In this module you will learn what processes are, how to display the current placement of the processes, how to change default process placement, to use the process reoptimize command, how to change a process's affinity, and how to configure process placement policies.
• Module 7: Cisco CRS-1 Multishelf Troubleshooting the Switch Fabric and Control Ethernet Network This module presents you with a logical approach to troubleshooting system data flow issues through the switch fabric, troubleshooting control Ethernet issues, and gathering information in the event a problem needs to be escalated to Cisco Technical Assistance Center (TAC). This module also discusses in-service diagnostics and how they are used.
