You can find the definitions in the Glossary.  \nwide-area network (WAN) page 82  \nwireless access points (WAP) page 84  \nmodular block diagram page 85  \nCisco Enterprise Network Architectures page 85 intrusion detection system (IDS) page 85  \ndata center page 87  \nCisco IOS file-naming conventions page 90 Feature Navigator page 91  \nflash memory page 92  \nrandom-access memory (RAM) page 92  \nTrivial File Transfer Protocol (TFTP) page 92  \ndynamic random-access memory (DRAM) page 92 release notes page 93  \nboot process page 93  \nPower-On Self-Test (POST) page 94  \nnonvolatile random-access memory (NVRAM) page 94  \nWAN interface cards (WIC) page 95  \nHigh-speed WAN interface cards (HWIC) page 95 Voice/WAN interface cards (VWIC) page 95 digital subscriber line (DSL) page 95  \nhot-swappable page 96  \nfaceplate page 96  \nIt is important to remember that before a new design can be created, the existing network must be investigated and characterized. The design team uses the network characterization to determine the strengths and weaknesses of the existing network that must be addressed with the new design.  \nExisting network devices may need to be updated to prepare for the introduction of new technologies. The network design team must complete a Design Requirements document and have it approved by the client before moving to the next phase of the project.  \nDocumenting the Existing Network  \nThe StadiumCompany case study (see Appendix B,“StadiumCompany Story”) has been provided as a guide through the documentation involved in a response to a Request For Proposal (RFP) . The network designer must create the documentation for an existing network that includes the equipment and applications that are part of the converged network. The documentation begins with gathering information from the existing network and developing an appropriate strategy for meeting the needs of the client.  \nCreating a Network Diagram  \nTypically, the first step in installing a new network is to take a detailed look at the existing network. The NetworkingCompany designer examines the existing network to  \n■ Determine whether the design goals are realistic and feasible  \n■ Determine whether the existing network meets the expectations for scalability, availability, security, and manageability  \n■ Identify where new equipment, infrastructure upgrades, and new services can be integrated  \n■ Ensure that old and new network devices, media, and functions can work together  \nUpgrading the Stadium Network  \nLike most organizations, the StadiumCompany has a preexisting network. The management wants to install a new network to  \n■ Better manage its existing voice, video, and data networks  \n■ Improve customer service  \n■ Reduce costs  \nThe NetworkingCompany designer reviews the existing network documentation. The StadiumCompany’s IT department network documentation contains most of the information that the designer needs concerning network organization and services.  \nThe network documentation should include the following:  \n■ Logical and physical diagrams of the network  \n■ Floor plans showing the location of wiring closets and wiring runs  \n■ Inventory lists of installed network equipment  \n■ Current network configuration files  \n■ Inventory lists of network applications  \nProducing a Network Topology Map  \nAs is the case with many businesses, the StadiumCompany’s ne","cbCaibEnE5MFv7U5","https://ap.wps.com/l/cbCaibEnE5MFv7U5","pdf",2530661,34,"English","# Objectives\n# Key Terms\n# Documenting the Existing Network\n# Creating a Network Diagram\n## Determining feasibility and requirements\n# Producing a Network Topology Map\n# Obtaining Information About Devices and Data Routes\n## Cisco IOS show commands\n# Investigating Existing Network Devices","[{\"question\":\"How does characterizing the existing network help the design process?\",\"answer\":\"It helps the design team identify strengths and weaknesses that must be addressed in the new design, informing decisions before creating a new design.\"},{\"question\":\"What upgrades or preparation are considered before integrating new technologies?\",\"answer\":\"The team evaluates whether existing hardware and software need updating and prepares the network for new technologies before moving forward.\"},{\"question\":\"What Cisco IOS commands are used to gather information for a network diagram?\",\"answer\":\"The chapter lists commands such as show version, show running-config, show ip route, show cdp neighbors detail, show controllers, and show tech-support to collect details about devices and data paths.\"}]","CHAPTER 3 - Characterizing the Existing Network | PDF",1792967285,86]
