Do you know what’s at the other end of the Ethernet cable plugged into the back of your computer right now, assuming you have a wired connection and not a wireless connection? The other end of that cable is probably plugged into an Ethernet switch. and that’s going to be the focus of this module. Specifically, you’re going to learn how an Ethernet switch makes intelligent framing decisions and how we can logically gr oup different switchports into different VLANs. And from a design perspective, we’re going to dive deep into the world of spanning tree protocol, which lets us have redundant connections in a switched network while avoiding some of the unsavoury side effec ts of having a layer - two topological loop. And we’re going to get started with all that in the next video, where we’re going to be examining a key piece of information that’s used by the switch to make that intelligent forwarding decision. It’s called a Ma c address. In an Ethernet network, every device is uniquely identified with a Misaddress, a media access control address. And that’s what we’re going to be focusing on in this video. We want to take a look at the structure and purpose of Mac addresses. The first thing I want you to understand about a Mac address is its length. It’s 48 bits in length. That’s as compared to an IP version 4 address that has 32 bits or an IP version 6 address that has 128 bits. And these 48 bits are written in hexadecimal notat ion. With hexadecimal, we don’t just count from zero to nine. When we get to ten, we say A, and eleven equals a B. So we have the digits 012 - 345 - 6789, ABCDEF. There are 16 possible values that we could have represented with a single hexadecimal character. So let’s think about this in binary. If I have 16 possible values, how many binary bits does it take to give me 16 possible values? Four. We can have four bits represent any of 16 different values, which means each hexadecimal digit is made up of four bits . Well, if we have a 48 - bit Mac address and we’re writing this in hexadecimal notation, that means we’re going to have twelve hexadecimal digits. And these twelve hexadecimal digits are broken into two different parts. The first half of the Mac address, th e first 24 bits, or the first six hexadecimal digits, is called the “Oui,” the organizationally unique identifier.
