As with many things, a solid foundation is required for one to build on. In this course, Switching Configuration for CCNA Data Center (200-150/200-155), you will learn the principles necessary to build a solid switching infrastructure, so you can build a highly functional network on top of it. First, you will learn the fundamentals of how switches work. You will then learn how to manage the Spanning Tree Protocol to ensure a consistent and predictable data flow across the layer 2 network. To wrap up the course, you will learn how to configure port channeling and VLANs. When you are finished with this course, you will have the skills to build and troubleshoot a Cisco switched network, as well as the necessary information to complete the network switching components of the CCNA Data Center certification exams.

Course Overview
Hi everyone, welcome to Pluralsight. My name is Greg Dickinson, and this is Switching Configuration for CCNA Data Center. I'm a network engineer at a regional bank in my home state of Alabama. I have 20 years of experience building and managing networks of all sizes in a variety of industries. I've managed to make a pretty decent career out of my love of technology, and I'm happy to share the knowledge I've gained over the years with whomever might listen. Over the last few years, I've specialized in Cisco VoIP technologies and the underlying networks that makes those systems work. This course will help you develop the skills necessary to build and maintain a stable Ethernet network. Many of the protocols that make modern switch to networks just work require configuration to ensure that they scale properly, and this course will step you through many of them. Some of the major topics that we will cover include the basics of the OSI or Open Systems Interconnect model, so you can accurately describe how data flows work in modern networks, basic switch configuration, so you can take a switch out of the box and set it up to work on your network, configuring the Spanning Tree Protocol, so you can ensure that the data flows across your switch network properly, and configuring VLANs, so you can secure traffic according to best practices. By the end of this course, you'll have an understanding of how layer 2 switching operates in a Cisco network. Before beginning the course, you ideally should be familiar with basic networking concepts such as IP addressing, as well as a familiarity with the Cisco command-line interface. I hope you'll join me on this journey to learn Cisco switching with the Switching Configuration for CCNA Data Center course at Pluralsight.

Basic Switch Configuration
Welcome in to Basic Switch Configuration. In this module, we're going to take a few minutes and perform basic switch configuration, just like the name implies. We'll perform a first-time setup, where we assign a username and password to the switch, so that you can log in to it remotely, and we also do interface configuration at a very basic level. We'll then move on to neighbor discovery, and discuss the 2 most popular neighbor discovery protocols, they're both Layer 2 protocols. First is the Cisco Discovery Protocol, which nearly every Cisco administrator or engineer has probably used at some point, and the Link Layer Discovery Protocol, which is what non-Cisco devices use, and we'll configure both of them, and compare and contrast the information that both of them provide.

Spanning Tree Protocol
In this module, we're going to discuss the Spanning Tree Protocol. First off, we will start with an overview of the Spanning Tree Protocol. We'll talk about its purpose and its function, and how it prevents loops on the network. We'll then talk about the different types of Spanning Tree Protocols, there are four different types, they all work a little differently. We'll be covering two of them in this module, and we'll be covering a third in a later module when we discuss VLANs. We'll then compare and contrast the two Spanning Tree Protocols that we'll cover in this module, 802. 1d, where the classic spanning tree versus the Rapid Spanning Tree Protocol, which is used in modern switches, and as the name implies, is more rapid than the 802. 1d Spanning Tree Protocol. We'll talk about the differences in the timers, and how they converge, and how the various port roles within the Spanning Tree Protocols impact the convergence time for the spanning tree. We'll then talk about how the 802. 1d and Rapid Spanning Tree Protocols handle notification of topology changes. And then finally we'll end up in a demo where we actually examine the spanning tree on a network, and we engineer a more optimal path through the network using the Spanning Tree Protocol.

Port Channeling Configuration
Welcome into our module on Port Channeling Configuration. You'll see as we go through this module that port channeling is fairly simple to set up, and can greatly enhance your network configuration with regards to network redundancy and high-speed links. In this module, we're going to talk about the use cases for port channeling, the main use case for port channeling is redundancy, as I just mentioned, but it also has an impact on the overall speed of the network because you're more efficiently utilizing all of the links between all of your networking devices. We'll then move on and configure it in a lab, and as with the other labs this will be done in the Cisco Packet Tracer so that you can follow along at home if you'd like, and finally, we'll see what impacts a port channeling configuration has on our overall network design, especially as it relates to spanning tree.

VLAN Configuration
So in this module we're going to discuss VLAN configuration. In this module we're going to talk about some VLAN use cases, i. e. why'd you want to use VLANs in the first place because it is an added configuration to a switch, it does complicate the switch configuration, and so there have to be some payoffs in order for you to go through this trouble. Mainly you'll use VLANs to limit layer-3 broadcasts, and we'll discuss exactly how that works. You'll also use it for security, and we'll talk about the use case for Voice-over IP. And then of course we'll move onto the configuration, where we'll not only configure VLANs themselves, but we'll also take into consideration VLANs impact on spanning tree, and making sure that the correct switches are the root of spanning tree for the VLANs we choose.
