Lab # 2 : Hub Vs. Switch Networks and Communication
Systems Department
TA. Anfal AlHazzaa
1
Lab Objectives 2
To create two small LANs contain three PCs using
Packet Tracer (one with hub and one with switch)
To differentiate between hub and switch function
To use Packet Tracer to simulate a small LAN
To show the movement of packet in each layer
Networks and Communication Systems Department - TA. Anfal AlHazzaa
Lab Content
The difference between hub and switch.
Using Packet Tracer to create and simulate
Small LAN connected by hub
Small LAN connected by switch
Showing the movement of the packet in each layer

The difference between switch and hub
4
Hub: forwards the packet that arrives on any of its
inputs on all the outputs regardless the destination
of the packet
Switch: forwards incoming packets to one or more
outputs depending on the destination(s) of the
packet

Scenario # 1 6
1. Create a simple LAN contains three PCs named (A, B and C) connected by hub (as shown in the following figure)
2. Perform a ping between PC “A” and PC “B” in realtime mode and simulation mode
Networks and Communication Systems Department - TA. Anfal AlHazzaa
Step 1(Adding 3 PCs) 7
1. Open The Packet tracer
2. Add three PCs to the workspace ( by select the
Generic PC under End Devices and drag it onto the
workspace)
3. Rename them and set their IPs as the following table:
PC name IP Mask
A 10.10.10.1 255.0.0.0
B 10.10.10.2 255.0.0.0
C 10.10.10.3 255.0.0.0

Change IP
Desktop tab IP configuration enter IP address
Repeat the same steps for PC “B” and PC “C”

Step 2 (Adding Hub and connection) 10
3 4 1
Under Hubs, select hub-PT
and drag it to the workspace
Under Connections, select
Copper Straight-through cable
to connect the hub with the 3
PCs

Step 3 (Performing a Ping in Realtime mode)
11
Click on PC”A” “Desktop”
tap Command Prompt
Write the following command Ping 10.10.10.2
Networks and Communication Systems Department - TA. Anfal AlHazzaa
*Repeat the same steps to test connection between PC “A” & PC” C”
Step 4 (Performing a Ping in Simulation mode)
12
Change the mode to simulation Click on Edit Filters button ,
uncheck show All/N
check on ICMP,

ICMP (Internet Control Message Protocol) is a
message control and error-reporting protocol
between a host server and a gateway to the
Internet

Step 4 (Performing a Ping in Simulation mode)
14
Add Simple PDU tool
Click on it
Click on the first PC
Click on the second PC
Click on Auto Capture/play button to run the Simulation

To show the movement of packet in each layer
16
Click on the packet envelope on the workspace to
bring up the PDU Information window like the one
shown in the screenshot (in the next slide)
This window contains the OSI model tab which
shows how the packet is processed at each layer of
the OSI model by the current device
