Network Documentation


In this lab, you will learn how to use various tools and techniques to determine and document IP network design. You will use the Windows Command Prompt to generate network traffic; Wireshark to capture and analyze the generated traffic; PuTTY to remotely access the Cisco Switch; and finally, you will issue IOS commands on the Cisco Switch to understand its various interfaces and inner workings.

Learning Objectives
Upon completing this lab, you will be able to:
• Develop a plan for identifying and documenting the logical IP network design and IP addressing schema based on data collected from Lab #1
• Use PuTTY to establish Telnet and SSH to the IP addresses of the identified
