CIS 81, Cabrillo College, Rick Graziani If you need assistance in using Packet Tracer, refer to the lab Using Packet Tracer.
Part 1: ARP and the Local Network
Step 1: Open the following topology
.Step 2: Select ARP and ICMP from the Event List Filters Enter Simulation mode and select only the ARP and ICMP protocols selected in the Event List Filters:
Step 3: Perform a simple, local Ping Select Add Simple PDU
Select Pc0 as the device that sends the ping:
Select Pc1 as the device that sends the receives the ping:
Instructions • Take your time going through this lab, it is not a race. Do not just click through the simulation, but examine, think and discuss what is happening. You will get much more out of this lab by doing so. • What to turn in: Answer the questions below. 1. Reviewing and Starting Packet Tracer • • To review or familiarize yourself with Packet Tracer, review the lab “Using Packet Tracer”. Start Packet Tracer and Open the file:
– The Internet is based on IP addresses
– Data link protocols (Ethernet, FDDI, ATM) may have
different (MAC) addresses
• The ARP and RARP protocols perform the translation
between IP addresses and MAC layer addresses
• We will discuss ARP for broadcast LANs, particularly Ethernet
The U.S. Department of Defense (DoD) created the TCP/IP reference model because it wanted a network that could survive any conditions.
The TCP/IP model has since become the standard on which the Internet is based. In 1992 the standardization of a new generation of IP, often called IPng, was supported by the Internet Engineering Task Force (IETF). IPng is now known as IPv6.
ARP is used as a tool for confirming that a computer is successfully resolving network Layer 3 addresses to Media Access Control (MAC) Layer 2 addresses. The TCP/IP network protocol relies on IP addresses like 192.168.14.211 to identify individual devices and to assist in navigating data packets between networks. While the IP address is essential to move data from one LAN to another, it cannot deliver the data in the destination LAN by itself. Local network protocols, like Ethernet or Token Ring, use the MAC, or Layer 2, address to identify local devices and deliver all data. A computer MAC...

eth0, the second Ethernet NIC is given
the alias eth1, and so on.

ARP performs IP address-to-Media Access Control (MAC) address resolution for
outgoing packets. As each outgoing IP datagram is encapsulated in a frame, source
and destination media access control addresses must be added. Determining the
destination media access control address for each frame is the responsibility of
