					              Activity 2 Tutorial Walkthrough
Purpose of this Activity:
    Introduce you to utilising Packet Tracer to develop networks virtually, without
      the need for any hardware.
    Allow you to gain some experience with different types of Network hardware
      and network designs & concepts.

Activity Objectives:
     Walk you through the steps of creating a network comprised of two PC’s
        connected together by a Switch, and show you how to connect devices together.
        For simplicity, the two PC’s and Switch are already on the desktop so you can
        focus on the PC configuration and network connections.
     Introduce you to the role of Switches on networks, and show you how Switches
        are able to function without any appreciably lengthy set-up time or
        configuration changes.
    to show the IP configurations needed and the type of cabling required, as
        different cables are required for certain connection types depending on the
        network
    assigning IP addresses and Subnet Masks for network communication
    assigning Host names to the devices, which make them more easily identifiable
        over a network..
    Introduce you to the different cable types, and which one you will utilise

This Activity is designed to build upon what has been shown in Activity 1, so please
ensure you have completed that Activity before attempting this one.

Note: You can also use Packet Tracer outside of the University by downloading it from
the Cisco Netacademy website, but your lecturer must register you on the Netacademy
service first, as you are required to log in to download Packet Tracer.

Firstly, please ensure that you have the latest version of Packet Tracer installed if
possible – the version utilised for the Activities is Packet Tracer 5.2 .




Version 1.1                                                                  Created 4/9/2009
The role of a Switch is to forward data on a network, for example to connect the PC’s in
a Classroom to the main University network, but this Activity will utilise two PC’s for
simplicity. Please feel free to carry out your own research on Switches, network cable
types etc to further your understanding.

The first thing you will notice is that in addition to the two PC’s in the previous
Activity, Activity 1, there is now a Switch. A Switch is simply a device whose role it is
to connect multiple nodes together in a network so they can communicate with each
other.




Firstly, you will need to click through the first Instruction windows, and then focus
back onto the main screen just above the PC’s. This is where the instructions are for
connecting the PC’s together, seen below.




Version 1.1                                                              Created 4/9/2009
You must select the right cable type (Copper Straight-Through) when following the
Instructions (It is essential that this Cable is utilised, as it is different to the Copper
Cross-Over cable used previously in Activity 1. Please research both cable types to
discover their differences). The FastEthernet port is how the University PC’s connect
to the University network – in the University labs, you can see the end connections
by the wall.




After connecting the devices together, you will need to re-name them by double-
clicking on each device, and typing its name into the box highlighted below under
the Config tab. This identifies them more meaningfully on the network, as names are
easier to recognise than individual IP addresses..




Version 1.1                                                                 Created 4/9/2009
Next, you will need to add the IP addresses listed for each PC below to the
FastEthernet port, under the Config tab (refer to screenshot below) to the PC’s in
order for them to communicate. However, as Switches monitor the IP addresses of
devices connected to them – and their role is forward packets – the FastEthernet
ports on the Switch itself do not need IP addresses. This makes Switches easier to
set up than other network devices.




                                                                        The IP address &
                                                                        Subnet Mask go
                                                                        here




Version 1.1                                                          Created 4/9/2009
The next step is to check that PC1 and PC2 can communicate with each other, so we
know the network connection works and can carry data.




To do this, we “Ping” the IP address of another device on the network, in this case
PC2. Double-click on PC1, and click the Desktop tab. Then, click the Command
Prompt icon.




Version 1.1                                                            Created 4/9/2009
When the Command Prompt screen appears, type the following: Ping 192 168.1.18
and press Enter. (this tells PC1 to send a signal to PC2, and PC1 will then receive
acknowledgements that the signals have been successfully received).




If PC2 cannot be reached, the following will be displayed showing the Request timed
out, i.e. PC2 did not respond to our Ping request.. You will need to look at your
network to identify the problem (incorrect IP address on PC2; Mis-typed Ping
command etc), and then type the ping command again.




Version 1.1                                                           Created 4/9/2009
If the Ping is successful, the following will be shown – this will confirm you have set
the network up correctly.




Then, answer the reflection question. This will help to show your understanding of
networks, and you can carry out some research of your own if you would like. The
final task is to click on the Check Results button, at the bottom of the Instructions
window, to check how well you did.




Version 1.1                                                              Created 4/9/2009
The screen below appears when you have successfully completed the Activity.




Clicking on the Assessment items tab shows you the different criteria you may or
may not have successfully completed. By using this information, you will know
where you have gone wrong, and can go back and correct any mistakes made.




Version 1.1                                                          Created 4/9/2009
