Internetworking Lab

Objectives

· Support the data networking courses including CES-440 (Data Communications), and CES-552 (Network Architechture and Protocols)

· Provide some practical understanding of data communications and networking and hands-on experience

· Focus on some important issues in data networking

Lab location - The lab is located at Salazar 2006

Lab experiments - The tile of the lab experiments and their objectives are:

1. Basics-Lab ◄ click here for the instructions

· Find out the Ethernet and IP addresses of your host station

· Test connectivity between your computes

· Monitor traffic at specific ports

2. SPT-Lab ◄ click here for the instructions

· Understand the main functions of a bridge: Learning, Forwarding, Spanning Tree.

· Demonstrate how LOOP AVOIDANCE is achieved using the Spanning Tree Protocol (STP) as specified in IEEE 802.1D

3. VLAN-Lab ◄ click here for the instructions

· Learn how vlan mechanism partitions a LAN and a big broadcast domain

· Learn basics of VLAN and configuration.

· Understand some advantages of VLAN

4. IP-Lab ◄ click here for the instructions

· Observe the need for router configuration

· Understand the subnet mask

· Understand the need of a routing mechanism in a router

· Learn how to configure a router with the static routing

5. RIP-Lab ◄ click here for the instructions

· Understand the RIP, its configuration

· Observe the routing protocol exchanges and how the RIP provides dynamic routing

· Observe routing convergence and how the network heals after a network failure

6. OSPF-Lab ◄ click here for the instructions

· Understand the OSPF, its configuration

· Observe the routing protocol exchanges and how the OSPF provides dynamic routing

· Observe routing convergence and how the network heals after a network failure.

7. SECURITY-Lab ◄ click here for the instructions

· Understand how to permit and deny accessing network resources and some aspects of security using router access list

· To get a feel as how the firewalls can be configured to deny certain exchanges

8. Appl-Lab ◄ click here for the instructions

· Observe how the applications obtain the destination addresses

· Observe how the TCP/IP applications (e.g., DNS, Telent, FTP) exchange the control information and data

· Observe how the TCP flags are used for the application exchanges

Format of Experiments - The lab instructions include the following

· Objectives – What does the student learn from the experiment

· Network Setup – Network and device configurations for the experiment

· Procedure – Steps to perform the experiment

· Report – Answers to the questions in the Procedure section and results

Student Lab Report

· For each experiment, it is expected each student writes a report to

o Answer questions in the instruction sheet

o Explain her/his observations from the experiment

o Analyze the results collected from the experiment

· Your report should be presented in MS Words

o Not more than 4 pages

o Single-space, font 10, Times New Roman

o At least 1 inch margin on each side

· Email your report by 5 PM the day it is due

· Students can work in groups not more than three per group

o Although each student writes her/his individual report, no copying

· Each student is expected to analyze the issues and understand for her/his benefit
