Introduction

Chapter 1 Overall Course Objectives

Design a network that meets a customer's requirements for performance, security, capacity, and scalability.

Assemble Cisco product lines into an end-to-end networking solution.

Additional Networking Information

Chapter 2 Small- to Medium-Sized Business Solutions Framework

Upon completion of this Introduction, you will be able to describe a framework you can use to simplify the complexities associated with analyzing customer network problems and creating Cisco scalable solutions.

Chapter 3 Identify Customer Needs-Characterize the Existing Network

Identify all the data you should gather to characterize the customer's existing network.

Document the customer's current applications, protocols, topology, and number of users.

Document the customer's business issues that are relevant to a network design project.

Assess the health of the customer's existing network and make conclusions about the network's ability to support growth.

Determine the customer's requirements for new applications, protocols, number of users, peak usage hours, security, and network management.

Diagram the flow of information for new applications.

Isolate the customer's criteria for accepting the performance of a network.

List some tools that will help you characterize new network traffic.

Predict the amount of traffic and the type of traffic caused by the applications, given charts that characterize typical network traffic.

Chapter 4 Design the Network Structure

Describe the advantages, disadvantages, scalability issues, and applicability of standard internetwork topologies.

Draw a topology map that meets the customer's needs and includes a high-level view of internetworking devices and interconnecting media.

Recognize scalability constraints and issues for standard LAN technologies.

Recommend Cisco products and LAN technologies that will meet a customer's requirements for performance, capacity, and scalability in small-to-medium-size networks.

Update the network topology drawing you created in the previous section to include hardware and media.

Recognize scalability constraints and issues for standard WAN technologies.

Recognize scalability constraints and performance budgets for major Cisco products.

Recommend Cisco products and WAN technologies that will meet the customer's requirements for performance, capacity, and scalability in an enterprise network.

Propose an addressing model for the customer's areas, networks, subnetworks, and end stations that meet scalability requirements.

Propose a plan for configuring addresses.

Propose a naming scheme for servers, routers, and user stations.

Identify scalability constraints and issues for IGRP, Enhanced IGRP, IP RIP, IPX RIP/SAP, NLSP, AppleTalk RTMP, and AURP, static routing, and bridging protocols.

Recommend routing and bridging protocols that meet a customer's requirements for performance, security, and capacity.

Recognize scalability issues for various Cisco IOS software features such as access lists, proxy services, encryption, compression, and queuing.

Recommend Cisco IOS software features that meet a customer's requirements for performance, security, capacity, and scalability.

Chapter 5 Build a Prototype or Pilot for the Network Structure

Determine how much of the network structure must be built to prove that the network design meets the customer's needs.

List the tasks required to build a prototype or pilot that demonstrates the functionality of the network design.

List the Cisco IOS software commands you should use to determine if a network structure meets the customer's performance and scalability goals.

Describe how to demonstrate the prototype or pilot to the customer so that the customer understands that the proposed design meets requirements for performance, security, capacity, and scalability, and that the costs and risks are acceptable.
