Lab 3: The OSI Model

Lab 3:  The OSI Model

by:  James Moore, Partner:  Matt Balderree

Objectives:  Using the command prompt determine your IP address.


Notes and Observations:  By using the Terminal application I was able to type in “ifconfig” and bring up my IP address associated on the KSU network.  Was also able to used the network utility built into the Mac which was easier.

Diagrams, Flowcharts, and Figures:  None (THROUGHOUT LAB)

References:  Lab handout (SAME USED THROUGHOUT LAB)

Questions:  What is your IP address?  What is your MAC address? (IP), and 00:0E:A6:82:FC:4D (MAC)

Objectives:  Bring up ARP table clear it and then ping your partners IP address.  Then check ARP table again to see any changes.

Notes and Observations:  Was able to bring the ARP table up but was difficult to read and had a different layout compared to Windows.  Was able to Ping partners Macbook and verify physical address.

Questions:  ARP stand for and do?  Address Resolution Protocol, used to translate protocol addresses to hardware interface addresses.  Did get a reply and why is ping useful?  Yes, see if able to connect to others and send/receive.  Neighbors physical address?  C8:BC:C8:9D:65:FF.  What method is used to translate a known layer 3 address into an unknown layer 2?  ARP.  What are layer 3 devices called?  Routers and Switches.  What is the de-facto standard for logical addresses today?  IP addresses.  How many bits do they require?  48.

Objectives:  In command prompt run a traceroute for and and compare the two.

Notes and Observations:  Used the Mac’s Network Utility to run a traceroute for both these addresses and discovered that even though the KWU campus is closer physically, I was able to ping the main campus at KSU faster.

Questions:  Describe the ping packet path?  The path to KSU= 4 hops and KWU= 14.

Objectives:  Connect to Cisco switch via PC serial cable.

Notes and Observations:  By connecting to COM1 and setting 9600 bits I was able to communicate with the switch and then type “show mac-address-table and find the switch MAC address.

Questions:  What information is provided in the switch MAC address table?  Physical address, VLAN, MAC address, Type, and Ports.  Does the MAC address in table match computer that is connected? Yes

Conclusion:  Using the OSI model and the options of pinging, traceroute, I was able to understand better the flow of the Network.  These methods will also be useful in troubleshooting network problems.  I also learned about Mac addresses and there digital fingerprint and physically identifying a computer.
