Hello, and welcome to the demonstration portion of our ARP fundamentals.
In this series of demonstrations,
I will teach you how to view and change the ARP caches in Windows,
Linux, and Cisco's iOS.
First, you'll understand the difference between static and dynamic ARP entries.
Then,
we will look at the ways to affect the ARP cache
through command-line interfaces.
In particular, I will show you how you can clear the system ARP cache,
how and when you can add and remove static entries,
as well as how you might change system ARP cache timers.
You will examine ARP protocol packet details to understand ARP
request and reply communication using live captures in
Wireshark Network Protocol Analyzer.
Lastly,
you will learn how to use ARP information along with your network routers
and switches to find and localize systems in your LAN. Let's get started.
