Lab #7
Extended LAN
Student Name:Shamma Nasser

Introduction
In the previous lab we setup the following LAN network:
In this lab we will create this same network again. Later on, we will create an extended
LAN network by interconnecting more than one switch together like so:
Exercise #1: Setting-up the LAN
In this lab we will create a LAN through switch.
1. Each group will be assigned to one PC.
2. Behind each PC there are numbered Ethernet ports. These are just connection that
end at the patch panel that is beside the switches. Record the port number that is
connected to your Ethernet card.
3. Go to the patch panel and connect an Ethernet cable from your port number on the
patch panel to the switch.
4. After each group does the previous steps, we will have a LAN consisting of the
PCs of all the groups.
5. Before we can test the LAN, we have to assign IP addresses to our PC.
6. Go to control panel  Network connections.

7. Right-click on your ethernet connection and click properties.
8. Scroll down and highlight TCP/IP and click the properties button.
9. Select Use the following IP address and for IP put 5.5.5.X (X here is any
number between 1 and 254, make sure the number you use is not used by any
other group). For the mask put 255.255.255.0, leave everything else empty. Test
your configuration by typing ipconfig in a cmd window.
Exercise #2: Making your folders shared.
1. Not all the folders on your PC are shared. So other computers cannot see all your
data.
2. However, if you want to share a new folder you can make it shareable.
3. Create a new folder on your desktop. Name it foldertest.
4. Now right-click on the this new folder and click properties.
5. Click on the sharing tab.
6. Check the “Share this folder on the network”
7. This allows others to see and read your folder. However, they cannot change
anything.
8. Checking “Allow network users to change my files” allows other to change your
files.
9. Click OK, and check to see if indeed another group can change your files.
10. Can other groups create new files? Or is it that they can only change existing
files.
Exercise #3:
1.
2.
3.
4.
Open a cmd window: Start  Run  cmd
Type ipconfig /all to see the information about your Ethernet connection.
What is the physical address value:____________________________
Although its named as a physical address in windows this is the Data-link address
as specified in the OSI model.
Exercise #4:
1. This part of the exercise will involve all the class.
2. In exercise #1 we all connected our PCs to the same switch. In this exercise we
will connect all our PCs through more than one switch.
3. Connect all the switches in the lab to each other.
4. Spread out your connections on the switches so that each switch has at least one
PC that is connected to it.
5. Now, check to see if your PC is connected to the other PCs on the other switches.
You can use the ping command or see if you can see the other PC in “My
Network Places”
