NE7112 CASE STUDY NETWORK DESIGN(Team Work) LABS M.E. COMPUTER SCIENCE AND ENGINERING (WITH SPECIALIZATION IN COMPUTER NETWORKS) 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 blindfold 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.

PROCEDURES: Open The CISCO PACKET TRACER software. Draw The Three PC using End Device Icons. Draw The CISCO 24 Port Switch Using Switch icon lists. Make The Connections using Straight-Through Ethernet Cables. Enter The IP Address To Each Machine. Check the IP address for Every PC using ipconfig or ifconfig Command. Check The Connections using Ping Commands. View The MAC Address Table. PHYSICAL CONNECTIONS :

PC-2 IP ADDRESS :
PC-3 IP ADDRESS :

ARP Table For Switch : ARP is Layer 2 to Layer 3 mapping; if our switches are Layer 2 and pings are on the same network, there is no arp cash on switches. PING PC 1 - PC 2 : 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. c:>ping 192.168.1.3
PING PC 1 - PC 3 c:>ping 192.168.1.3
