ANALYZING THE PERFORMANCE OF VARIOUS CONFIGURATIONS AND PROTOCOLS IN LAN

CASE STUDY 1 ANALYZING THE PERFORMANCE OF VARIOUS CONFIGURATIONS AND PROTOCOLS IN LAN

1.1. Establishing a Local Area Network (LAN)

The main objective is to set up a Local Area Network, concepts involved in this network are IP

addressing and the Address Resolution Protocol (ARP). The required equipment's are

192.168.1.1, 192.168.1.2, 192.168.1.3, Host A Host B Host C, Switch/HUB, three PC`s equipped

with at least one NIC, one HUB or Switch and the necessary cables. Once the physical LAN is

set up the hosts need to be configured using the ifconfig command. To verify communication

among the machines the ping command is used. Next, to manipulate the routing tables at the

hosts to understand how machines know where to send packets. Since the ifconfig command

places a default route into the routing tables this route must be deleted. To blind fold the

machine. The ping command is used again to show that communication is no longer available.

To re-establish communication the routes are put back into the routing table one host at a time.

Communication i once again verified using the ping command.

REQUIREMENTS:

v Three Windows PC or 3 Linux PC, Each PC must Have One NIC cards.

v One Switch or One Hub.

v Three Straight Line LAN (cat-5) Cables with RJ-45 Sockets.

v Power supply

v Class C IP Address. Using Static IP configuration.

v Basic Network Configuration Commands.

v Cisco Packet Tracer 6.0.1

PROCEDURES:

v Open CISCO PACKET TRACER software.

v Draw The Three PC using End Device Icons.

v Draw The CISCO 24 Port Switch Using Switch icon lists.

v Make The Connections using Straight-Through Ethernet Cables.

v Enter The IP Address To Each Machine.

v Check the IP address for Every PC using ipconfig or ifconfig Command.

v Check the Network Connections using Ping Commands.

v View the MAC Address Table.

v View the PC’s ARP table.

NETWORK TOPOLOGY:

HOST A IP ADDRESS:

HOST B IP ADDRESS:

HOST C IP ADDRESS:

VERIFY LAN NETWORK CONNECTIVITY

ping command is a Network Utility Command. ping tools use Internet Control Message Protocol

(ICMP). ping used to verify the connection between source PC to Destination PC.

HOST A TO HOST B

c:>ping 192.168.1.2

HOST A TO HOST C

c:>ping 192.168.1.3

VIEW ARP TABLE:

WHAT IS ARP (ADDRESS RESOLUTION PROTOCOL)?

ARP associates an IP address with its physical address. On a typical physical network, such as a

LAN, each device on a link is identified by a physical or station address that is usually imprinted

on the NIC.

ARP OPERATIONS:

An ARP request is broadcast, An ARP reply is unicast

HOST A ARP TABLE:

PC>arp -a

RESULT:

Thus the Experiment Was Configured Successfully.
