Lab 1-3: Packet Tracer Review-Class Lab

Open up Packet Tracer and drag the following onto the workspace:

Connections:

Use "Straight Through" Cables to connect laptop/server to switches and switches to router (FastEthernet ports on Router) and pay attention to the interfaces you use

Subnet for Foster is 192.168.3.0/24

• Subnet for Skiff is 192.168.1.0/24

CNCS Router

FastEthernet 0/0 - Foster Switch FastEthernet 0/1

FastEthernet 0/1 - Skiff Switch FastEthernet 0/1

Foster Switch

FastEthernet 0/2 - Foster Laptop FastEthernet0

Skiff Switch

FastEthernet 0/2 - Skiff Server FastEthernet0

On CNCS Router:

• Assign the IP 192.168.3.1 and subnet mask 255.255.255.0 to the Interface connected to the Foster Network
• Assign the IP 192.168.1.1 and subnet mask 255.255.255.0 to the Interface connected to the Skiff Network
• For some reason - you have to change the port status icon to on so you can see that things are connected (idk why that was turned off)

Configure IP's subnet mask and Default Gateway on the Laptop and Server:

• On the Laptop assign 192.168.3.20, mask 255.255.255.0 and 192.168.3.1 as the Gateway
• On the Server assign 192.168.1.40 Mask 255.255.255.0 and 192.168.1.1 as the Gateway

Ping server from laptop

Submit: screenshot of successful ping

Traffic Analysis in Packet Tracer

Go into "Simulation Mode" in Packet Tracer (stopwatch on lower right)

From Laptop - open up "web Browser" on Laptop Desktop

Enter the IP address of server and hit "go"

Use Capture/Forward to send to packets hop-by-hop

Complete the TCP Handshake and the HTTP Request

Review Packet Details under the Simulation Panel

SUBMIT: Screenshot of Details of a HTTP packet

Practice Saving Router config

Go back to Real-Time mode (clock)

From Router: Config Tab: Save NVRAM

Power Off Router- use power button on physical tab

Power back on

Use Fast Forward button to get links back

Check router config to make sure Interface IP's are still there

They are still there!
