CCNA/ICND Course

Hello and welcome to my interconnecting Cisco Network devices class. I am excited about teaching this class, because this class is preparation for the Cisco 640607 test. But in addition to that, the information that you'll learn from this class is going to help you with your entire networking career. So why is this important information to know? Because it is the basis for all network training. It will help you to obtain a Cisco CCNA certification. Well what we are going to talk about will apply to any type of network training that you choose to pursue. The types of knowledge that you will gain from this class are your general networking knowledge, a trouble shooting network knowledge, and then of course, the specifics of the Cisco IOS in command line interface. We will discuss the OSI model; the OSI model is the model that all protocols are built after. It is the model that started networking. We will discuss the development for the model and the reason and then the overview and layered architecture of the OSI model; then we'll discuss bridging and switching. Bridges and switches do approximately the same thing. And we'll discuss how bridges and switches work; the descriptions that we use when we talk about them, types of bridging and switching, the spanning tree protocol which we use when we connect multiple bridges or switches, and then virtual local area networks, we will discuss what VLANs are and how to create them. Then we will look at Local Area Network Protocols; the most common local area network protocol is the TCP/IP protocol suite and we will examine the TCP/IP protocol suite in detail. Then we will take a look at IP address classes; we take a look at how the IP address classes came to be and what we used to use and then what we are actually using right now. We'll also look at how to configure and verify IP addresses in the Cisco command line interface. Then we'll take a look at IPX addresses, and compare and contrast IP addresses with IPX addresses. In order for packets to be able to communicate through a network, they have to use the same language. We'll talk about encapsulation of packets, which allows them to present themselves as the same language or as something that the other side would recognize. We'll talk about why encapsulation exists and many different types of encapsulation. And then we'll discuss packet terminology in general; you may have heard of packets referred to as frames, or segments or messages, we will talk about where all that came from, and how we refer to packets at different levels. Then we will discuss the other side, the wide area network protocols. We'll define frame relay and look at how to configure frame relay. Then we will take a look at monitoring frame relay, once it is configured; we will turn our attention to ISDN, and we will look at how to set up ISDN and then how we can use ISDN as a tool for wide area network communication. We'll look at ISDN protocols and channels, reference points, all the aspects of ISDN. Also define PPP, point-to-point protocol and we'll take a look at PPP encapsulation on a wide area network. Then we'll turn our attention to routing, we'll discuss what routing is and how routing provides flow control. We'll discuss how routing information protocol works, in other words, how routers get their information and then can set up the routes that data packets will take throughout a network. There are many different types of routing protocols, we'll discuss RIP and IGRP, and then we will contrast distance factor versus link state protocols. Then we'll turn our attention to LAN design; we'll discuss full-duplex vs. half-duplex communication, and how Ethernet works, the carrier-sense multiple access with collision detection protocol. We'll discuss fast Ethernet and then guidelines and distance limitations for different types of Ethernet. The Cisco IOS will also be prominent in what we discuss, and in our next section, we'll finish the summary starting with the Cisco IOS. That's next. sco IOS will also be prominent in what we discuss, and in our next section, we'll finish the summary starting with the Cisco IOS. That's next.
