Lab 1‐3: Packet Tracer Review - AidanP017/Aidan-NET-330 GitHub Wiki

Purpose

In this lab, we created a basic network in Cisco Packet Tracer as a review of practice.

Establishing Connections

To start, the following network was created in Packet Tracer. Straight-through cables were used to connect the Foster laptop and Skiff server to switches, and connect the switches to the router.

The Foster laptop was set up with the following IP information:

Meanwhile, the Skiff server was set up with the following IP information:

The CNCS router was configured with the Foster and Skiff subnets on ports FastEthernet0/0 and 0/1, respectively.

To ensure that proper connectivity was established, the Skiff server was pinged from the Foster laptop.

Traffic Analysis

To better understand how packet traffic operates across the network, we analyzed the traffic in simulation mode that was initiated by sending a request from the Foster laptop's web browser to the IP address of the Skiff server.

Using the simulation mode controls, packets were monitored hop by hop across the network. Afterward, we located an HTTP packet that arrived at the Skiff server and viewed its contents.

Saving Router Configurations

The last practice that was reviewed was saving the existing router configurations in the event that the router was disabled.

Back in real-time mode, we navigated to the Config tab for the CNCS router and saved the NVRAM.

After restarting the router in the Physical tab, we fast forwarded the network to reestablish the links and checked the router configurations to verify that the IP information was still there.
