Lab 3.1.2 Creating a Logical Network Diagram

Task 1: Use Cisco IOS Commands to Obtain Information about the Network

Step 1: Discover and document the first device

a. Your instructor will advise you as to which PC is configured for Administrator access to the network.

Access this Admin PC and issue the ipconfig command from the command prompt to discover the

default gateway.

b. Telnet from the command prompt (or use a terminal program such as HyperTerminal or TeraTerm) to

the IP address of the gateway device and enter privileged EXEC mode using the passwords given

above.

c. Issue Cisco IOS commands, such as those shown here as well as others you choose to use, to learn

about the device.

show running-config

show ip route

show interfaces

show ip interface brief

show version

Record this information in the first Device Table at the end of this lab.

d. Issue Cisco IOS commands such as those shown here to discover information about connected

devices.

show cdp neighbors

show cdp neighbors detail

It may take a few minutes for the network to converge. If you do not see any neighboring devices

initially, repeat the command until you do.

Document the information you gather in the appropriate Device Tables.

e. Close the Telnet session by issuing the exit command.

Step 2: Discover the remaining devices

a. Telnet to the IP address of a device connected to the first device interrogated, and repeat the process

in Step 1. Document this new device in an appropriate Device Table.

b. Repeat this process until all devices in the network are discovered and documented.

As you work through the network devices, record the details of each and sketch a diagram of the

network devices and their interconnections. When IP address information has been recorded, what other commands could be used to confirm connectivity and trace interconnections between devices?

ping

tracert dan traceroute

Can a connectivity trace be relied upon to return details of all the pathways between devices? Give

reasons for your response.

Tidak, semua jalur tidak akan dikembalikan karena routing pada Layer 3 dan STP pada Layer 2 akan menyebabkan hanya satu jalur antara perangkat yang akan ditampilkan jika koneksi berlebihan atau ada alternatif.

Task 2: Use Cisco Network Assistant to Obtain Information about the Network

Step 1: Launch Cisco Network Assistant

a. Launch the Cisco Network Assistant program on the PC connected to the network.

b. Network devices can be accessed for monitoring and information gathering. From the Applications

menu, click Connect.

c. In the Connect dialog box, select the Connect To: option and enter the default gateway of the Admin

PC in the field, as shown.

Step 2: Record the network topology

  1. Record the displayed topology. The display will look similar to this sample.
  2. Continue to connect to each known device. Record the topology displayed and compare it with the diagram that you created from the results of Task 1.

Step 3: Collate the network information

Assemble your completed network Device Tables and Topology Diagrams into your FilmCompany case study portfolio for use in later labs.

Step 4: Clean up

Erase the configurations and reload the routers and switches. Disconnect and store the cabling. For PC hosts that are normally connected to other networks (such as the school LAN or to the Internet), reconnect the appropriate cabling and restore the TCP/IP settings.

Task 3: Reflection

a. These techniques were used to discover and document an enterprise LAN. Would the same

techniques work for an enterprise network that included WAN links?

b. Could these techniques be used in a network that included routers and switches from a manufacturer

other than Cisco? Why or why not?

Jawab:

Cisco Network Assistant hanya mendukung perangkat yang tercantum di FAQ program. Jenis-jenis perangkat lunak dapat digunakan untuk jaringan multi-brand.

Step 3: Test the restored IOS image

a. Verify that the router IOS image is correct. Power cycle the router power and observe the startup

process to confirm that there were no flash errors. If there are none, the router IOS should have

started correctly.

b. Further verify the IOS image in flash by issuing the show version command, which will show an

output similar to this:

System image file is “flash: c1841-ipbase-mz.124-1c.bin”

Step 4: Clean up

Erase the configurations and reload the router. Disconnect and store the cabling. For PC hosts that are

normally connected to other networks (such as the school LAN or to the Internet), delete the IOS image file from the TFTP directory, reconnect the appropriate cabling and restore the TCP/IP settings.

Task 3: Reflection / Challenge

Step 1: Switch IOS Upgrade

As a challenge lab, research and list the steps required to back up the Cisco IOS image file from a switch to a TFTP server. In addition, list how to restore or upgrade the IOS image from the TFTP server to the switch.

Pengaturan server TFTP dan perintah CLI yang digunakan untuk melakukan backup dan upgrade switch IOS sama seperti untuk router. Perbedaan yang signifikan adalah pengaturan dari alamat IP pada interface 1 VLAN dari sakelar

 

Step 2: Non-operational Device

The performance of IOS image backup and upgrade for routers and switches as described in this lab

presumes that the device has a current, fully operational IOS to allow the configuration of IP connectivity prior to copying the image file. However, there may be cases where the current IOS is corrupt or for some other reason the device will not boot with an operational IOS.

a. Research and record the ROMMON process that enables a router to be configured and its IOS uploaded if the device has this problem.

b. Research and record the X-Modem or similar process that enables the IOS of a switch to be uploaded using the serial (console) connection if the device has this problem.

The following documents are typical Cisco.com resources describing these recovery processes:

Step 4: Clean up

Erase the configurations and reload the router. Disconnect and store the cabling. For PC hosts that are

normally connected to other networks (such as the school LAN or to the Internet), delete the IOS image file from the TFTP directory, reconnect the appropriate cabling, and restore the TCP/IP settings.

Task 2: Reflection / Challenge

Prepare a troubleshooting checklist based on the router startup stages and the hardware and software

features associated with each stage. Format the checklist so that if it is noted that a stage was unsuccessful, the possible problems can be readily identified. For example, for “IOS not loaded” enter “ROMON prompt displayed.” Prepare a second checklist listing possible router faults or problems. For example, “no cooling fan sound,” “LEDs not illuminated or showing unusual behavior,” or “unexpected ROMON prompt displayed.” For each problem listed, enter the stage of the router startup process that failed.

 

Lab 3.3.2 Determining the Router Hardware Options

Task 1: Inspect a Cisco 1841 ISR

Step 1: Physically inspect the external features of the router

Examine the router. In the table below, identify and match each item number in the figure with the description. In addition, record the number of each interface and port on the router with the description.

Is a module installed in Slot 0? No

How many Fast Ethernet interfaces does the router have?

2

WIC-2T two serial interfaces

Is a module installed in Slot 1?

No

Which of the modules and ports have the potential to be upgraded to improve the router’s

capabilities?

Slot 0 dan Slot 1, flash card slot

 

Step 2: Use IOS show commands to inspect the router

a. Referring to the topology diagram, connect the console (or rollover) cable to the console port on the

router and the other cable end to the host computer with a DB-9 or DB-25 adapter to the COM 1 port.

Ensure that power has been applied to both the host computer and router.

b. Establish a HyperTerminal or other terminal emulation program connection to the router.

c. From the privileged EXEC mode prompt of the terminal, issue show run and show flash:

commands.

Record the number and type of interfaces. Typical results are shown.

interface FastEthernet 0/0

interface FastEthernet 0/1

interface Serial 0/0/0

interface Serial 0/0/1

interface VLAN1

Record the details of the memory (DRAM, flash) modules.

Flash 32 MB

SDRAM 128 MB

Step 3: Compare the physical and IOS inspections

Are there any differences between the physical and IOS inspections?

No

Observed differences could be due to the IOS having features implemented in the software that do not have the hardware module installed, or loopback interfaces may be configured.

If an installed hardware interface does not appear in the configuration, it may be faulty or may not be correctly installed. In some cases, slots must be filled consecutively; in other cases, certain module types can only be installed into specified slots.

Task 2: Examine 1841 Router Hardware Options

After establishing the current hardware status of the router, examine the technical documentation to

determine the potential for upgrading and growth.

Step 1: Access the Cisco.com documentation

a. Go to the website http://www.cisco.com.

b. In the Quick Links pane on the right, select Documentation.

c. Under Select a category, click Routers. Under Select a product, click the Cisco 1800 Series

Integrated Services Routers link.

d. Review the documentation links displayed.

e. Under Product Literature, click the Data Sheets link. Note the range of data sheet documentation

available.

f. Click Cisco 1800 Series Integrated Services Routers: Cisco 1841 Router (Modular).

Step 2: Record the router hardware information

a. Read through the Cisco 1800 Series Integrated Services Routers: Cisco 1841 Router (Modular)

document, noting the structure and format of the information.

b. From Table 1, Architecture Features and Benefits of Cisco 1841 Router, record the following

information:

The number of different modules and interface cards that are supported: >30

Default memory capacity:

32 MB of flash and 128

MB of synchronous dynamic RAM (SDRAM)

Cisco IOS versions supported:

12.3T, 12.4, 12.4T

Feature Sets and Beyond

c. From Table 5, Product Specifications of Cisco 1841 Router, locate and record the following

specifications from the Architecture section.

d. From the Table 6, Modules and Interface Cards the Cisco 1841 Router Supports, list the 10

different categories of interface card (WIC) supported by the 1841 platform.

e. From Table 6, what feature does the Advanced Integration Module (AIM) enable to be installed in an

1841 router?

VPN encryption

Step 3: Consider possible hardware options

The 1841 ISR has removable and interchangeable modules. Various optional modules can be installed in the router to provide specific capabilities. These modules are installed either by inserting them into slots on the chassis, or by opening the chassis and plugging them into connectors inside.Flash memory and interface cards fit into slots on the chassis and are installed and removed without opening the chassis.

There are three types of interface cards for the 1800 series modular routers:

  • • WAN interface cards (WICs)
  • • Voice WAN interface cards (VWICs – in data mode only on the Cisco 1841)
  • • High-speed WAN interface cards (HWICs)

The following components plug into connectors inside the chassis and are installed and removed only by

opening the chassis:

  • • Advanced Integration Module (AIM)
  • • Synchronous dynamic RAM (SDRAM) small-outline dual in-line memory module (SODIMM

Summarize the changes that are possible for this router. This information is important to have and consider when planning and designing the network upgrade.

If the router is not at its limit of these features, candidates for upgrading could include:

Flash memory (if larger IOS required)

SDRAM

Slot 1 Ethernet switch 4-port module

Slot 1 WIC-2T – 2 serial interfaces

Slot 1 Other WAN technology DSL/ISDN

Step 4: Clean up

Erase any configurations and reload the router. Disconnect and store the cabling. For PC hosts that are

normally connected to other networks (such as the school LAN or to the Internet), reconnect the appropriate cabling and restore the TCP/IP settings.

Task 3: Reflection

Network device capabilities are continuously developing. Consider the advantages of a modular platform over that of a device with a fixed hardware platform.

Modularitas memfasilitasi kustomisasi perangkat untuk memenuhi kebutuhan jaringan lokal.
Peningkatan dan penggantian modul mengurangi biaya dan waktu dari layanan.
Perangkat Modular menyediakan desain jaringan yang fleksibel dan scalable.

Lab 3.4.3 Performing a Wireless Site Survey

Step 1: Configure the wireless client PC1

a. Referring to the topology diagram, configure the PC1 wireless NIC address to match the address

shown in the topology for PC1.

b. Ensure that power has been applied to the Wireless Router.

c. From the command prompt of PC1, ping the Wireless Router to confirm network connectivity.

If the pings fail, troubleshoot and establish connectivity.

Step 2: Monitor signal strength using Network Stumbler

a. On PC1, open the Network Stumbler program.

b. In the Network Stumbler window, expand the SSIDs section and locate the SSID of the wireless

router being used in this demonstration.

c. Expand that SSID number to find the Wireless Router MAC address. Click that address to open the

Signal/Noise monitoring window to the right.

The Green vertical bars in the moving graph indicate signal strength. Red bars indicate signal noise.

The higher the green bars, the more signal strength. Additional information may be found in the Help

menu of the Network Stumbler program (Help > User Interface > Configuration Dialog > Graph

View).

d. Record the signal strength of the Wireless Router at its current location and include its distance from

PC1.

Step 3: Relocate the wireless AP

a. Unplug the power cord on the Wireless Router and move the device to a location outside the room,

preferably more than 25 feet away, and plug the power cord into the nearest wall outlet within that

area.

b. Wait for the Wireless Router to power up, and then return to PC1 to view the Signal/Noise meter.

Has the signal strength been reduced?

Ya

Record the signal strength of the Wireless Router at the current location and include its distance from

PC1.

Step 4: Relocate the wireless AP to a secure location

a. Unplug the power cord on the wireless router and move the device to a secure wiring closet, outside

the classroom. This room should be able to be locked and also provide an AC wall outlet to plug in

the Wireless Router power supply.

b. Plug the power cord in and power up the Wireless Router. While waiting for the Wireless Router to

power up, close the wiring closet door, and return to PC1 to view the Signal/Noise meter.

Has the signal strength been reduced?

Ya

If no wiring closet can be used, the Linksys antennas can be removed to simulate a long distance.

Remove the antennas and place the router under a desk or in a cabinet.

c. Record the signal strength of the Wireless Router at the current location and include its distance from

PC1.

Will the current placement of the Wireless Router be a good location to provide wireless access to

other rooms within the area?

Judge how far away end devices can be placed from the wireless Access Point and determine the

number of end devices that the AP could provide service to.

What obstructions tend to cause the largest drop in signal strength?

 

Step 5: Clean up

Return the wireless router to the classroom. For PC hosts that are normally connected to other networks

(such as the school LAN or to the Internet), reconnect the appropriate cabling and restore the TCP/IP

settings.

 

Lab 3.5.2 Creating an Overall Project Goal

Step 1: Gather information about the company goals that this network upgrade will facilitate

Consider what FilmCompany sees as benefits that the upgraded network will provide to their business in

terms of their new stadium contract. These business benefits will not be the direct technical improvements

that networking technicians and engineers may see. A business manager does not necessarily see the

network in terms of bandwidth, latency, efficient protocols, or device operation. They are more likely to

consider issues of profitability, flexibility, customer service, and reliability.

As a network designer, you take into account all the information obtained through interviewing the company managers and key members of the staff.

a. Draft informal notes of what you consider to be the business benefits in this case.

b. Use word processing software to create a Project Goal document based on these notes.

c. Organize or group your informal notes and save these in your Project Goal document.

General headings could include:

  • • Financial goals
  • • Job management goals
  • • Customer communication goals

Step 2: Summarize important goals in a list

a. Examine the general goals recorded and summarize these as three or four key points.

Begin each point with a verb, such as Provide, Increase, Improve, or equivalent word. Try to include a measurable achievement if possible.

For example:

Provide the stadium with a broadcast-quality, 30-minute highlight video package within 3 hours of the conclusion of an event.

b. Save the list of important goals in your Project Goal document.

Step 3: Develop an overall project goal statement

a. Write a single statement that introduces the summarized important goals.

The proposed network upgrade will enable FilmCompany to increase its share of

the sports event video market through:

  • • Improved response times to customer requests
  • • Improved processing and delivery of video content across the network
  • • Improved communications access to customer facilities
  • • Ability for improved flexibility in meeting customer needs

b. Add this statement to your Project Goal document.

Step 4: Obtain agreement from the company on the project goal statement

FilmCompany has to agree with your assessment of the Project Goal before you proceed further with the

design. If this is agreement is not obtained, the network you design may not meet the FilmCompany overall business requirements. An agreement provides clarification and acknowledgement of why the upgrade is to occur and what it is to achieve.

a. Discuss your Project Goal document with another student and arrive at an agreed-upon Project Goal.

It may be necessary to amend the statement and important goals before agreement is reached.

b. Save your Project Goal document and retain it for the next stages of this network design case study.

Step 5: Reflection

Consider the issue of communication between the network designer and a manager of the company

considering an upgrade of the business network. The network designer is trained in network operation and performance and how to optimize network resources and technologies to best provide network services. To the manager, the network is only one of a number of business tools that the company may use. The business manager probably wants to improve profitability and sees an enhanced network as a tool to help achieve that goal. A business manager is not likely to relate to a goal that is expressed solely in technical terms, such as an upgraded LAN with higher bandwidth, less latency, and maximized server utilization. Although most designers may want to talk about network capabilities, the lifecycle approach is about customer requirements and enabling the business process.

Discuss some strategies that will enable clear communication between a network designer and a business manager so that the resulting Project Goal document represents business needs that ultimately can be met by a network design.

Pada tahap awal siklus desain, penting bagi siswa mengembangkan kesadaran tentang keharusan usaha yang akan meng-upgrade drive jaringan dari alam.


Lab 3.5.3 Creating a Scope Statement

Step 1: Consider how meeting the project goals will impact the existing network

a. As the network designer, look at the existing network topology and the services that it provides.

Consider how much of the network is affected or changed as a result of the project.

b. Record what areas of the existing network will have to change or will in some way be affected by

meeting the project goals.

Draft informal descriptive notes of these possible changes. Organize these notes under headings

such as:

  • • Access Layer
  • • Distribution Layer
  • • Core Layer
  • • Data Center
  • • Network Services
  • • WAN Access

c. Use word processing software to create a Project Scope document based on these notes.

Step 2: Refine and record the proposed changes to the existing network

a. Distinguish between possible upgrades to existing network resources, such as additional servers or

VLANs, and completely new additional resources, such as QoS and WAN links.

b. Record which areas and users will be affected by these changes.

c. Include these network changes in your Project Scope document.

Step 3: Define the areas of the existing network not covered by the project

It is important to note the parts of the existing network that are not within the areas covered by the project.

These out-of-scope areas are defined so that there is no misunderstanding between the NetworkingCompany and FilmCompany management.

In this case study, for example, providing IP telephony services may be a future consideration, but it is not

within the scope of this project.

Clearly state these out-of-scope areas in your Project Scope document.

Step 4: Compile and present the project scope document

FilmCompany has to agree with your assessment of the Project Scope before you proceed further with the design. An agreement ensures that there is a common understanding about what is included in the network upgrade project and what is not included.

a. Discuss your Project Scope with another student to ensure that the issues you present are clear.

b. Save your Project Scope document and retain it for the next stages of this network design case study.

Step 5: Reflection

It is important that a project have clearly defined boundaries so that all parties know what is included and

what is not. Consider the issues of ensuring that customer business and network needs are satisfied before the scope is broadened beyond what is feasible and required.

What strategies could be used to ensure that a project scope is developed that is clear and appropriate?

Pastikan bahwa setiap layanan jaringan baru dan teknologi yang tidak termasuk dalam ruang lingkup semata-mata karena mereka dapat, pastikan mereka selaras dengan kebutuhan perusahaan dan tujuan.
• Apakah orang yang berbeda, baik dari perusahaan desain jaringan dan bisnis, meninjau lingkup
proyek dan memberikan interpretasi mereka untuk memastikan bahwa itu berarti hal yang sama untuk semua orang.

Lab 3.5.4 Developing Network Requirements

Step 1: Record the company business goals and constraints that will influence the network design

As the network designer, you need to identify and prioritize the business goals of FilmCompany as defined in the Project Goals document. Develop your understanding of what these goals are from the FilmCompany case study information.

a. List these goals in order of priority.

b. Expand and consider the details of how these goals can be achieved using the network as a platform.

c. Note any constraints that these expanded goals may impose on the network design, such as retaining

the current number of IT and network support staff.

d. Use word processing software to create a Network Requirements document.

e. Clearly state the business goals and constraints in the document.

Step 2: Record the technical requirements that will influence the network design

a. Evaluate each of the business goals and determine the technical requirements to meet the goals.

List these technical requirements under the headings of:

  • • Scalability
  • • Availability and Performance
  • • Security
  • • Manageability

b. Initially, list all technologies that may be able to meet these technical requirements.

c. Include these requirements in your Network Requirements document.

Step 3: Record the user requirements that will influence the network design

a. Consider the types of users that will influence the network design. These users may be onsite, in the

office, in the video editing room, offsite (at the stadium), or mobile. Which types of users generate the heaviest amount of network traffic? Which types generate the lightest traffic?

How might different types of users be grouped for Access Layer purposes?

b. Include these requirements in your Network Requirements document.

Step 4: Record the application requirements that will influence the network design

a. Consider the type of applications that will influence the network design.

What applications are essentially device-based, with minimal network requirements?

Which applications are network-intensive?

Which applications and services are delivered onsite, in the offices, and which may need to be delivered offsite over the WAN or to mobile users?

b. Include these requirements in your Network Requirements document.

Step 5: Develop the network requirements

a. Refine the technical requirements of the network to match user and application requirements.

What compromises may have to be made to ensure that the project remains within the business

constraints?

b. Finalize the technical requirements of the network that will meet the project goals.

c. Discuss and review your Technical Requirements document with another student to ensure it addresses all the business, user, and application requirements within the Project Scope and does not unnecessarily address out-of-scope requirements. Modify the document as necessary.

d. Save and retain your Technical Requirements document for the next stage of this network design

case study.

Step 6: Reflection

Developing the technical requirements of a network that meets the project goals, while remaining within

scope, requires knowledge of the available and appropriate technologies and services.

Discuss strategies that will ensure that a network design team is up-to-date with networking technologies and their applications.

Lab 3.5.5 Analyzing an Existing Network

Step 1: Document and confirm existing network topology, addressing, and naming schemes

a. Examine the existing network topology diagram.

Record the current addressing scheme in a table.

Associate device names with addresses on the table.

b. Highlight any inconsistencies in the naming and addressing schemes.

For example:

  • • Naming some devices by location and others by function
  • • Inconsistent or confusing use of abbreviations
  • • Some gateway addresses as the first address of a subnet, others as the last address

c. Use word processing software to create a Current Network document.

Step 2: Identify those parts of the existing network that currently meet the project technical requirements

a. Examine the network topology and specifications.

Record which current features meet the technical requirements of the proposed network upgrade.

  • • Capacity (bandwidth, address ranges, VLANs)
  • • Redundant links
  • • Router and switch interfaces and ports
  • • Router and switch feature sets, memory, and processing capability
  • • WAN
  • • Wireless
  • • QoS

b. Include these strengths and capabilities in your Current Network document.

Potential strengths may include:

  • • New wiring and adequate communications closets
  • • Adequate space for a new data center
  • • Servers and PCs are current models and will not need replacement
  • • Some existing network switches and routers can be used in the new design

Step 3: Identify those parts of the existing network that can be scaled to meet the project

technical requirements

a. Examine the network topology and specifications.

Record which current features do not meet the technical requirements of the proposed network

upgrade but can be scaled within the capacity of the network to do so.

  • • Capacity (bandwidth, address ranges, VLANs)
  • • Redundant links
  • • Router and switch interfaces and ports
  • • Router and switch feature sets, memory, and processing capability
  • • WAN
  • • Wireless
  • • QoS

b. Include these scalable features and capabilities in your Current Network document.

Step 4: Identify those parts of the existing network that do not to meet the project technical requirements

a. Examine the network topology and specifications.

Record which current features do not meet the technical requirements of the proposed network

upgrade and what additional networking resources are required.

  • • Capacity (bandwidth, address ranges, VLANs)
  • • Redundant links
  • • Router and switch interfaces and ports
  • • Router and switch feature sets, memory, and processing capability
  • • WAN
  • • Wireless
  • • QoS

b. Include these weaknesses and shortfalls in your Current Network document.

Possible weaknesses include:

  • • Flat network design
  • • Insufficient bandwidth at Distribution Layer, no true Core Layer
  • • Servers poorly located
  • • Multiple networks, difficult to maintain
  • • Poor IP addressing structure
  • • No dedicated bandwidth for WAN connectivity
  • • Limited wireless implementation
  • • Limited security implementations

Step 5: Obtain agreement and authorization from the company to continue with the network upgrade design

a. Finalize the Current Network document so that the strengths and shortfalls are clearly and precisely

presented.

b. Discuss and review your Current Network document with another student to ensure that it clearly

states which parts of the network meet the technical requirements of the upgrade project and which

parts do not. Amend the document as necessary to clarify any areas that could be misunderstood. At

this stage of the network design process, a meeting with the FilmCompany management would be

held to obtain their agreement and authorization to continue with the design of the upgrade.

c. Save and retain your Current Network document so that it can be incorporated with the previous

documents to complete this network design case study.

Step 6: Reflection

Consider the resources and information that will facilitate the task of analyzing a current network.

  • • Having up-to-date documentation showing such information as addressing, device names,

VLAN allocations, switch port assignments

  • • Systematic and consistent host names, descriptions, and addressing schemes
  • • Software tools that record data flows and device identification
  • • Efficient and accurate fault and incidence reporting and clearance documentation to highlight

and record problems
