Join Russell Long for an in-depth discussion in this video What you need to know, part of Cisco ICND2 Cert Prep: Switching.
- [Instructor] So let's cover a little bit of what you should probably already know going into this course. Now first things first: prerequisites. What is required before you start this course? First thing I would say is I would like you to have finished an ICND1 course or a CCENT certification course. Why? Because a lot of what we do is built upon that foundation. CCENT is a newer certification that many of you might not know is dedicated to the content of ICND1.
Cisco changed this a few years ago to make CCENT the gateway for many other Cisco subjects such as wireless, and other types or disciplines within the Cisco world. Now we're dealing with routing and switching here. So we need you to take ICND1, and understand the network fundamentals, especially for this class including local area networks. Now incredibly important you understand how frames are passed to switch to switch, how frames help switches in the learning process.
All of that is really important to build upon the foundation you already have. So if you don't understand that, some of the concepts I'm going to be introducing are going to be tough for you to grasp fully. Next I want you to understand basic internet connectivity. How does that work? How does a packet get delivered from one network to another? What is the host-to-host delivery process? And next, basic network device connectivity. How does that work as well? So you should have a very basic understanding of VLANs.
We're going to dive deeper down the VLAN hole. Don't worry I'll do a tiny bit, a tiny bit of review so I'm not just throwing things at you that you learned years ago. So you'll have a little bit of review there, but remember it's a steep learning curve if you don't already know much of the content. So we should also know where we are in our studies. Now as I said ICND1 is the entry level to many of the subjects. So that is the CCENT certification.
I recommend that you go through that certification instead of trying to get your all-in-one CCNA. Break those exams up, take the CCENT first, get that information under your belt before moving on to this course. Which is ICND 2, the associate level. Where we're working on our CCNA for routing and switching. This is a Cisco Certified Network Associate, that's what the CCNA stands for. And we're going to break this up. If you look at the arrow, we're going to break this up into five separate courses.
The first course, which we're on now, which is ICND 2: Switching. We're going to focus on those layer two devices in our environment. I found this is an easier way to learn rather than just throwing everything in a book, and having you go through different things. I don't like that. We're going to break things up: Switching, and then we're going to go into Routing, and we're going to go into WAN Technologies, Infrastructure Services, and then Infrastructure Maintenance. That's going to be your entire ICND 2 course. At the end, I would very much expect you to be able to pass the CCNA exam.
So here we are right here at ICND 2: Switching. If you are going to continue on with your studies, you would move on to the professional level, or CCNP, Cisco Certified Network Professional. This level consists of three separate courses. Not like ICND 1 maps to CCNT, ICND 2 maps to CCNA, CCNP is actually three different exams. We have switching, we have routing, and we have T-shoot. So very interesting topic there.
After that, if you've accomplished your CCNP, you can go up to you CCIE level, Cisco Certified Expert. So you're at the expert level, right? This is a very difficult exam. It is a written and a lab that is done in person. Highly difficult exam, not a lot of people pass And then after that is the Cisco Certified Architect at the very pinnacle of your studies. So let's go ahead and get started with switching. Now what will we learn from this switching course? We will understand our Layer 2 domain.
That's what we're trying to get out of this exact course. We're going to understand our mac addresses, how to troubleshoot VLANs, trunk, dynamic trunking protocol, VLAN trunking protocol, all things Layer 2 we're going to discuss as it relates to the ICND course two, and for the real world level of CCNA.
- VLAN basics
- Voice VLANs
- VLAN Trunking Protocol
- Spanning Tree Protocol
- How STP modes work
