Analyze the test plan shown above and answer the following questions:

a. What are the four main sections of the test plan?

How many tests are defined within the test plan in this lab?

In which testing subsection would you find the types of commands or analysis tools used to determine

if the test was successful?

d. In which main test plan section would you find a description the devices and cabling used to build the

prototype for the test plan?

e. In which main testing section would an overall description of the tests to be performed and the

reasons why they are being specified in the test plan?

Connect the switch to the router as shown in the Test Plan topology diagram.

Connect the PC1 and PC2 hosts to the switch using the ports indicated in the Test Plan topology table.

Using the IP address information from the Test Plan table, configure PC1 and PC2.

Connect a PC with a console cable to the switch to perform configurations using a terminal emulation

program. Confirm that the switch is ready for lab configuration by ensuring that all existing VLAN and general configurations are removed. Remove the switch startup configuration file from NVRAM.

Switch#erase startup-config

Erasing the nvram filesystem will remove all files! Continue? [confirm]

Press Enter to confirm. The response should be:

Erase of nvram: complete

If the switch has previously been configured with VLANs, it will necessary to delete the VLAN

database information file. From the privileged EXEC mode, issue the following commands:

Switch#delete vlan.dat

Delete filename [vlan.dat]?[Enter]

Delete flash:/vlan.dat? [confirm] [Enter]

If there was no VLAN file, this message is displayed.

%Error deleting flash:/vlan.dat (No such file or directory)

It is recommended that the delete command not be issued as: delete flash:vlan.dat.

Accidentally omitting vlan.dat from this command could lead to the complete IOS being deleted

from flash memory. Issuing the reload command to restart the switch may not always clear the previous VLAN configuration; for that reason, the power cycle (hardware restart) step is recommended.

c. With PC1 connected to switch port 4 and PC2 attached to port 14, attempt to ping from PC1 to PC2.

Would you expect the ping to be successful?

Why or why not?

PC IP addresses are on different networks (PC1 is on net 10.0.10.0/24 and PC2 is on net 10.0.20.0/24 and in different VLANs.

d. Change the IP address of PC2 to 10.0.10.5 so that the two PCs are on the same network and ping again. Would you expect the ping to be successful?

Why or why not?

e. Move the cable for PC2 to a port that is in the VLAN 10 range (Fa0/2 to Fa0/12) and ping again.

Would you expect the ping to be successful?

Why or why not?

f. Change the IP address for PC2 back to 10.0.20.2 and move the cable back to Fa0/14 in VLAN 20.

This test demonstrated that the PCs from the main-net cannot communicate with the PCs on the voice net without assistance from a Layer 3 device.

Why is it important to develop a test plan and prototype network behavior?

a. Make a list of all the necessary equipment and cables required to build the LAN portion of the

proposed network design.

b. Make a list of all the VLANs required to implement the design.

Determine the appropriate IP addressing for the devices identified in Step 1a.

Determine an appropriate IP address range for each VLAN identified in Step 1b.

The format used to create the test plans may vary. The format used for this and subsequent labs is similar to the document used by the Cisco Customer Proof-of-Concept Labs. It is divided into sections to make it easier to read and understand. The test plan is a formal document that can be included in a proposal. It verifies that the design functions as expected. Many times, customer representatives are invited to view the prototype tests. In these cases, the customer can review the design and see for themselves that the network meets the requirements.

Download and review the LAN Design Test Plan. Record a description of each section and what types of

information each section requires you to enter.

In this example test plan, much of the information has already been entered for you.

Enter the purpose of the test.

Think about why you want to test the LAN portion of the design.

Enter what functions of the LAN design you intend to test.

Three tests are entered for you to use with this test plan.

Test 1: Basic Connectivity

Test 2: VLAN Configuration

Test 3: VLAN Routing.

Using the information you recorded in Task 1, Step 1a, fill in the chart in the equipment section. List

all network devices and cables. Two personal computers are already listed to assist in the testing of

the design. If your school lab does not include the required equipment for the design, discuss possible substitute models with your instructor.

a. Copy the LAN topology from the diagram created previously in Lab 5.2.4

Enter the IP addressing information recorded in Task 1, Step 2a, in the IP Address Plan chart.

Enter the VLAN names and IDs recorded in Task 1, Steps 1b and 2b, in the VLAN plan.

Enter any additional information that you want the technician performing the test to be aware of

before the test begins.

In the Test Description section, enter the goals for each of the three tests that you plan to perform.

Test 1 is completed as an example of how to fill in the information. In the Test Procedures section, enter the steps that are necessary to perform each planned test. In the Expected Results and Success Criteria section, enter what you expect the results to be if all the steps in the Test Procedures section are followed correctly. Determine what results need to be observed for the test to be considered a success.

Following the procedures in the Test 1: Procedures, execute the various commands and record the

results of the testing.

Copy and paste the output of the various commands into a document using Notepad or a word

processing program. Save or print the document to include with the completed test plan.

Compare the results that you observed during the testing with the expected results listed in the Test

1: Expected Results and Success Criteria section.

Determine if the testing indicates that the network meets the success criteria. If it does, indicate that

the test is successful.

Step 1: Configure the prototype network

Step 2: Verify the VLAN configuration design

Step 3: Record the test results in the Results and Conclusions section of the test plan

a. Follow the steps you created in the Test 3: Procedures section of the test plan to configure the router

to route between VLANs.

b. Using the topology diagram shown in the Design and Topology Diagram section of the test plan,

configure the appropriate router to route between the VLANs created in Task 2.

c. Following the steps you listed in the Test 3: Procedures section, console into the switch that is directly

connected to the router. Configure the link between the switch and the router as an 802.1q trunk link

and permit all VLANs across the trunk.

d. Console into the router and configure the router interface directly connected to the switch for 802.1q

encapsulation.

e. Configure the router with the appropriate IP addresses for the various VLANs. Verify that the routes

appear correctly in the routing table.

f. Copy and paste the initial device configurations into a document using Notepad or a word processing

program. Save or print the document to include with the completed test plan.

a. Verify that the PCs are configured to be in different VLANs and that the IP address configuration on

the PCs is correct. Configure the IP addresses assigned to the router, in Step 1e, as the default

gateway addresses for the PCs. Verify that the default gateway addresses are on the same networks

as the addresses assigned to the PCs.

b. Following the procedures in the Test 3: Procedures, ping from PC1 to PC2. Copy and paste the

results into a document using Notepad or a word processing program. Save or print the document to

include with the completed test plan.

c. Execute the various show commands to verify that the routing is correct.

d. Record the results in the Test 3: Results and Conclusions section of the test plan.

a. Compare the results that you observed during the testing with the expected results listed in the Test 3: Expected Results and Success Criteria section.

b. Determine if the testing indicates that the network meets the success criteria. If it does, indicate that

the test is successful.

Was the prototype testing of the FilmCompany LAN design successful? Did having a test plan to work from help you organize your testing?

Is the design able to scale to meet the growth, or do budget constraints limit the types of hardware and

infrastructure that can be included?

Do the IP addressing and VLAN configurations allow for the proposed growth?

Can the selected hardware be upgraded easily without a major reconfiguration of the network?

Can new Access Layer modules be integrated into the network without disrupting services to existing users?

Does the design provide for the smallest possible failure domains?

Are there multiple paths and redundant devices to protect against losing connectivity to important services?

If, in Step 1, you identify weaknesses in the proposed design, what risks do these weaknesses present to

FilmCompany?

In what ways could the proposed design be improved to reduce the areas of risk?

In the Results and Conclusions section of the test plan, record any weaknesses, risks, and suggested

improvements.

Why do you think it is important to identify weaknesses and risks in the proposed design before presenting it to the customer? What are some reasons that weaknesses cannot be corrected?

List any cables that are needed to connect the devices as shown in the topology diagram. Use the information from this list to fill out the chart in the Equipment section of the test plan document.

Using the information contained on the Prototype Network Installation Checklist and the partially completed Server Farm Design Test Plan document, determine what procedures should be followed to perform each test listed on the plan. Using Test 1 as an example, fill out the procedures sections for Tests 2, 3, and 4.

Think about which commands and tools (such as ping, traceroute, and show commands) you can use to verify that the prototype network is functioning as designed. Decide which outputs to save to prove the results of your tests.

Carefully identify what you expect the results of each test to show. What results would indicate that the tests were a success?

Show vlans, show spanning-tree, show interface, failure of ping between VLANs

Show vlans, show interface, show IP route, traceroute, and successful ping between VLANs.

Show running config, show interface, show IP route, traceroute, attempts to access unauthorized resources denied.

a. Fill in the Expected Results and Success Criteria section for each test, using the information collected above.

b.Save the completed Server Farm Test Plan. It will be used in subsequent labs.

Why is it important to think about and document the expected results and success criteria for each of the

individual tests?

Determine if the test was successful. If not, discuss your results with your instructor and the other students in your class. Perform the test again if necessary.

Examine the test plan, checklist, and other documentation to determine how ACLs can support the security goals.

Decide which devices should be permitted, which protocols should be used, and where ACLs should be

placed.

Determine if the test was successful. If not, discuss your results with your instructor and the other students in your class. Perform the test again if necessary

Examine the test results and conclusions. How this network would be affected if:

1. The number of servers was doubled?

2. The S2 switch had a system failure?

3. A new branch office with 25 new hosts was added?

Now that you have followed the process of prototyping from creating the plan through testing and recording results and conclusions, what are the advantages and disadvantages of using a simulation program, such as Packet Tracer, compared to building the prototype with physical devices?

Examine the server farm topology as one entity and as a part of the entire FilmCompany topology. Look for each of the risks and weaknesses listed in the chart. Describe the devices, connections, and issues that you find, or record None found if the design appears to avoid risks in that area.

Basic router and switch configurations were modified to support the following protocols and functions.

Evaluate the results and conclusions that were drawn from the testing. Identify any areas where modifications to the configuration would provide better results, both now and in the future.

From the analysis performed in Task 1, list each risk or weakness and suggest possible changes to the

design to minimize or eliminate it.
