Exercise 2.6.1 :
Topology layout and building a small network
Address table
This lab does not include address tables.
Topology
learning target
- Correct identification of cables used in the network
- Physical connection point-to-point switching network
- Verify basic connectivity for each network
Introduction:
Many network problems can be solved at the physical layer of the network. Therefore, it is essential to have a clear understanding of which cables are used for network connections.
At the physical layer ( layer 1 ) of the OSI model , end devices must be connected with a medium (cable). The type of media required depends on the type of device connected. For the basic part of this lab, you will use straight-through cables or jumper cables to connect the workstation to the switch.
Additionally, two or more devices communicate using assigned addresses. The network layer (Layer 3 ) requires unique addresses (also called logical addresses or IP addresses) so that data can reach the appropriate destination device.
The addressing scheme for this lab will be applied to workstations and used for communication between devices.

Task 1 : Create a peer-to-peer network
Step 1. Select experimental partners
Step 2. Obtain the equipment and resources to be used for the experiment.
Equipment required:
- 2 workstations
- 1 Ethernet cable
At the end of this task, the completion rate should be 0% .
Click the > (Next) button to continue.
Task 2 : Determine the cables used in the network
Before you connect a device, you must determine the type of media you want to use. This lab uses crossover and straight-through cables.
Use a crossover cable to connect the Ethernet ports of the two workstation network cards. This is the Ethernet cable. When you look at the plug, you'll notice the orange and green wires on opposite ends of the cable.
Use a straight-through cable to connect your router's Ethernet port to the switch port, or connect your workstation to the switch port. Ethernet cables are also used here. When you look at the plug, you'll notice that every pin is in exactly the same position on both ends of the cable.
Step 1. Connect to a peer-to-peer network.
Use the correct Ethernet cable to connect the two workstations together. Connect one end of the cable to the NIC port on PC1 and the other end to PC2 .
What type of cable are you using?
crossover cable
At the end of this task, the completion rate should be 33% .
Click the > (Next) button to continue.
Task 3 : Configure the address and test
Step 1. Apply the Layer 3 address to the workstation.
To complete this task, you must follow the step-by-step instructions below.
- Click on the PC you want to assign an address to.
- Click the Desktop tab
- Click on the IP Configuration tab
- Enter the IP address 192.168.1.2 (for PC1) in the IP address box . (For PC2, enter the IP address 192.168.1.3.)
- Press the tab key and the subnet mask will be automatically entered. The subnet address should be 255.255.255.0. If this address is not entered automatically, please enter it manually
- Press X to close the IP configuration window
Step 2. Verify connectivity.
To test connectivity, follow these instructions:
- Click PC1
- Click the Desktop tab
- Click the Command Prompt tab
- Type ping 192.168.1.3 and press Enter
What is the output of the ping command?
C:\> ping 192.168.1.3
Pinging 192.168.1.3 with 32 bytes of data:
Reply from 192.168.1.3: bytes=32 time<1ms TTL=128
Reply from 192.168.1.3: bytes=32 time<1ms TTL=128
Reply from 192.168.1.3: bytes=32 time<1ms TTL=128
Reply from 192.168.1.3: bytes=32 time<1ms TTL=128
Ping statistics for 192.168.1.3:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms
C:\>
If the ping command displays an error message or is unable to receive replies from other workstations, troubleshoot as necessary. Possible areas for troubleshooting include:
- Verify that the IP addresses on both workstations are correct
- Make sure the correct type of cable is connected between workstations
If you unplug the network cable and then ping another workstation, what is the output of the ping command?
C:\> ping 192.168.1.3
Pinging 192.168.1.3 with 32 bytes of data:
Request timed out.
Request timed out.
Request timed out.
Request timed out.
Ping statistics for 192.168.1.3:
Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),
