Assignment 2

Due Monday, February 9, 2009 (at the end of lab)

Preliminaries

  1. This assignment should be done in lab on February 4 & 9. You may write the answers the required questions directly on this handout.
  2. Choose a team of 4-5 people with whom you will work on this assignment. (Please try to balance the number of people on your teams.) List the members of your team:
  3. Your team will work with three workstations in the lab. NET1-NET3, NET4-NET6, NET7-NET9, NET10-NET12, or NET13-NET.
  4. Turn in only one assignment per team.
  5. Note : there is a limit to the number of users that can telnet to the switch at one time, so you will need to take turns with the other groups to work on this part of the assignment.

Tools Available for Your Use

Workstations  You will be using the workstations in the lab are named: NET1, … , NET.  For this assignment you will be using Windows XP Home Edition. Alcatel Switches You may telnet directly to the Alcatel switches. The switches are managed swiched and have a fairly sophisticated set of commands that you may use.

(a) What is the Mac address of the computer that is logged into the Alcatel switch? (b) What is the Mac address of the other two computers you are using? (c) What are Mac addresses used for? (Hint: You may look on-line or in the text book for help with this question.) (d) Try to ping from Switch2/Switch3 (i.e., while you are logged on to the switch) to the other computers attached to the switch. What are the results? What machines (by name and IP address) were you able to contact?

Part 3 -- Exploring Our Lab/Network through Ubuntu Linux

Reboot your three computers so that they are running Ubuntu Linux. Note: You may need to have superuser status to perform some of the commands you will be using. At the command line, simply type sudo to become a superuser. You may need to do this each time you need to be superuser.

  1. Physically connect your computers to Alcatel Switch4. Change your IP addresses and subnet masks so that you can communicate with Switch 4 and the other computers in the lab.
  2. Use the command ifconfig. (a) Read the man page on ifconfig. (b) List the NIC card/s that is/are on your machine. (c) List the MAC address on your NIC card. (d) Change your IP address and subnet mask using ifconfig.

Part 4 – Using RS-232 to Connect to the Alcatel Switch

Using the laptop computer in lab, connect to Alcatel Switch 2 using an RS-232 connection and the console port. Follow the directions in the Switch manual to:

  1. Set the RS-232 communication parameters to match those of the switch.
  2. Login to the switch.
  3. Do not change the switch name or password.
  4. Change the switch time and date.
  5. Physically attach your team workstation (NET1-NET10) to Switch 2 (IP address: 192.168.2.1) using a CAT-5 cable. Change your IP address and subnet mask so that you can communicate with Switch
  6. Use the RS-232 connection to examine your workstation connection to the switch. What can you find out about your connection? (For example, connection port number? IP address? MAC address? Other information?)

Part 5 – Using DHCP to obtain an Internet Connection

Using your computer in lab, connect to Alcatel Switch 4.

  1. Using the Windows XP networking commands, configure your NIC to use DHCP to obtain a dynamic IP Address.
  2. Check to see if you can access the Internet using a web browser.
  3. What IP address got assigned to your machine?
  4. Where did this address come from? Draw a diagram showing the connection of your workstation to the Internet. Show all the intermediate networking devices along the path that you know about.
