Overview
This lab is part of a series of lab exercises designed to supplement coursework and
provide students with a hands-on training experience based on real-world applications.
This series of lab exercises is intended to support courseware for CompTIA Network+ ®
certification.
This lab will review protocols that operate at the internetwork and transport layers of
TCP/IP. These protocols are internetwork layer protocols such as ARP, ICMP, and IP and
at the transport layer, UDP and TCP. Students will review IP address configuration,
discover facts about network communication using ICMP and the ping utility, and will
examine the TCP/IP layers and become familiar with their status and function on a
network.
This lab includes the following tasks:
Use network utilities and protocols from the TCP/IP suite
Use a network packet analyzer, Wireshark ®, to examine the ARP protocol
Capture and analyze transport layer packets
,The ipconfig command allows you to view your network configurations and to test
communication with other computers. Used on its own, the ipconfig command shows
basic information such as the name of the network interface, the IP address, the subnet
mask, and the default gateway. Combined with the /all switch, it shows a detailed set of
information about the TCP/IP settings. The ipconfig command lists the IP address
configuration for your computer’s network interfaces along with other network settings.
