Hello and welcome to our second recording. My name is Tyler McMinn. In this video, we're going to take a quick look at what an Aruba Enterprise switch actually looks like. I'm going over some of the basic components and directing you to where you can actually take a view of some of these switches yourself without leaving your house or having to purchase one. Sit back and enjoy. Let's jump on in and take a peek. Hewlett Packard Enterprises has been developing in selling switches back since 1998. With the introduction of Aruba in 2016, we've updated the name of our ArubaOS operating system, and the switches that run on it, the prohibition switches, to share that same Aruba name even though those switch fabrics had been around for a very long time. The new operating system, which started its development around this time as well and has released to market over the last year or two is the Aruba CX operating system. That's going to be the focus of this switching class or this discussion on switches. We're going to be using that CX operating system to build out our networks. This is the portfolio of CX switches that Aruba offers today with the newer or newest member of the family being the 6200 down here, let me grab a different pen for that, there we go. These are the edge static port switches that we would offer in a campus or a small business. These are all layer three switches. They all run the new CX operating system from the data center spine/core huge top of the line chassis 8400, which can handle over a million routes, down to our 6200 edge switch, which was released as a bit of a replacement for the 2930Fs and everything in between. The two chassis where you would apply either campus or data center, you can use both 8400 and 6400 in a campus solution, or if you just need a data center with a couple racks of servers, the 6400 supports up to 100 gigabits per second of throughput on some of its cards, just as the 8400 does. It's really just a matter of scale. What they're offering now is entire solution with a single operating system using CX, whether you're talking just a small branch with 24 ports and you've got your APs up and running powered your connectivity, your layer three routing, everything taken care of, or you're talking about the core of a huge college campus or a hospital network there with the 8400. Or, if you're looking at a specialized spine-leaf design in the data center. Now for us, just starting off in networking, we're not going to be using these in our homes. However, when you go to work or when you're working with organizations from home, those organizations are often going to need something at the enterprise level to handle the amount of throughput at those locations. These are what we would call enterprise-grade. To get a closer look at these, you can actually see what's involved. On Hewlett-Packard enterprise's website, they have a bitly link here. This as a URL shortcut I put together to a 3D Catalog and opening up this Catalog, which I have here, you can actually download this for free and play around with it. This is what it looks like. You can go to the Aruba networking section and we have our access points our wireless controllers, our switches, click on say the Switches for CX, and the CX switches are going to show that family that I showed in the previous slide, the 8400, the 8325, and the 8320. These 8000 series switches are the routing portion. They focus much more on layer three. In other words, they behave as if they were routers out of the box. That's where they're designed to be placed. In the previous slide where they showed us the location here and you saw the term Core and aggregation being thrown around, that's where these 8000 series really are designed to be placed. They're not really meant to be at the edge where you actually plug in your computer. They're are meant to plug in other switches into these core devices. If I had a 6300 that is meant to be at the edge of the network where you were actually going to plug in our computers, and then the high-speed up links here would connect to the high-speed ports that you would use somewhere on your blades here or somewhere on the High-Speed ports that you have on this 8320, or even 8325 in the core or the distribution of your network. There's this tearing that goes on where your computer plugs into the edge switch, like the 6300. Hundred, and then the Edge switch would uplink to the core set of switches for redundancy. The cores are just that. They're meant to connect to other sections of the network, either other switches or service providers, or maybe a data center, or something along those lines. I should probably use a smaller pen. You guys get the idea. This is the portfolio layout of this. While we're not going to get to much into the design part of it, those of you that have played around with some design, hopefully that makes a little more sense. In this class, in these series of videos, we're really just focused on the edge and what we can do there. Whatever venue you want to use, it doesn't really matter. These antennas, these four switch ports that you would have at your home, those all are basically the same as these 63, 6200s as far as placement of those devices. They're meant for you to plug in your computer or whatever printer that you want to use, just like you would do here on these ports. Plug in your computer or your printer or docking station or even a dedicated access point with its own antennas, you could do that off of these ports just fine. They actually power the APs themselves, which is pretty cool. The routing side of the house, I'll draw that in red, is where you have a dedicated interface that's meant to route your traffic out to the internet. We learned in the last video that we actually connect to a special device called a modem that translates the internet and not only does it take the Internet service providers physical connection; fiber, copper, DSL, whatever it is, and allow us to use a regular Ethernet cable to plug that in, so a little green cable here for Ethernet, but it also handles our addressing and our routing for us. This box that you would use at a retailer is very inexpensive. It's a standalone box, it doesn't really play well with other devices. It's meant to just do its own thing, and it's only meant to handle a few dozen devices honestly. Beyond that, I've seen them run 100 devices,150 devices, and they generally start to do not so great. Whereas something like even our entry-level or Edge 6200 could handle thousands and thousands of devices in its forwarding tables and even do routing for those devices. These are switches. They switch packets, they're switching on the wired side, they're wire connected devices, and they're specialized in that regard to be able to support a full enterprise deployment. If you want to see them in action, let me get rid of all of that, here's what you do is if you check out that bit.ly link and you open up this 3D tool, you can go to CX switches and click on, for example, this 6300 or the 6400. The 6400 is interesting, or any of these really. The 6400 is a chassis-based switch. In the enterprise, this is where you have essentially a bunch of switches that you can swap out. Here you can see what we call line cards, but what they really are are switch fabrics that give you the switching capability, but they need something. They need a house or a chassis, a housing, to be able to provide power and connectivity for them. If you go over here, you can always reset it. You can spin these around, look at the back of them. On the back, you've got a lot of fans here that are swappable. You can pop them out if one of them needs to be replaced for whatever reason, or power supplies that are also swappable. They're redundant. If you lose any one of these fans or power supplies, the whole chassis will continue to work without even dropping a packet. You can pop these out. Actually, they have little animation options here. How do I pop out a fan? Click a little fan animation and it'll show you exactly what the fan tray looks like where you can replace these. Field replaceable means that you could replace them in the field if you needed to go on-premise and fix someone's 6400. There you go. If you swing around to the front, these are a list of all the models of different switches or line cards that fit inside the 6400 housing. Pretty cool. If I want to look at one with a bunch of high-speed uplinks, I can click that animation. It just shows it. That one was not so much fun. Let's do this module, see if that shows an animation there. You can flip it around to the front and actually see how those little arms pop open to slide the tray out. That's the switch right there. But obviously if this was sitting in a closet without anything, there's no way to power it or connect it, so it relies on that housing. What you see on the screen here is when you first log in to a factory reset switch, what's it's going to look like. I'm going to go over this in the next video, and we're actually going to go over encapsulation, a little bit of theory on how packetization works, how the data actually is cut up into smaller packets to be able to traverse the network, and we're going to be starting the switch. I look forward to see you in the next video, thank you again for your time.
