3-Day Hands-On Course
Course Description
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.
Course Objectives
What you will learn:
- Discuss the Cisco CRS-1 multishelf
architecture and terminology assiciated with the multishelf system
- List and describe the features and functions
of the field replacable 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
- Compare and contrast the data flow in a
standalone CRS-1 16-slot 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 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,
inclduing 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
- Conifgure 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
- Gather information to send tot 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
Intended Audience
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 the
Cisco CRS-1 multishelf routing system.
Prerequisites
The following are prerequisites for this
course:
- Completion of the Cisco CRS-1 Essentials
course
- Knowledge of Cisco CRS-1 16-slot LCC
configurations and operations
- Experience maintaining and troubleshooting the
Cisco CRS-1 16-slot LCC in a service provider production
environment
Course Outline
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 need to have documented
interconnections prior to beginning the configurations of the
multishelf fabric and control Ethernet. Students are presented
with both single-module and multimodule fabric cabling schemes. In
addition, this modules 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
theOIM 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 a processes'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.
