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

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

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

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

ICMP (Internet Control Message Protocol) is a

message control and error-reporting protocol

between a host server and a gateway to the

Internet

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
