Advanced Services’ Cisco CRS-1 Multishelf Operations,
Maintenance, and Troubleshooting (CRSMulti) Version 1

Length: 3-day Workshop

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.

You will learn to:

• Discuss the Cisco CRS-1 multishelf architecture and terminology associated the a multishelf system
• List and describe the features and functions of the field replaceable units (FRUs) of the
  Cisco CRS-1 multishelf routing system
• Compare and contrast the fabric architecture in a standalone CRS-1 16-slot line-card chassis (LCC) and a Cisco CRS-1 multishelf routing system
• Describe the roles of the intrachassis and interchassis control Ethernet network operations
• Understand the interconnection of the optical array cables from the S13 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-1ab 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 fun
• 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 to
