CCNA VLANs

Chapter 1 - Introduction Welcome to the start of the CCNA training series! We’re going to take the network fundamentals that you already know, and build on them to take you to the next level. If you don’t have the fundamentals yet, don’t worry, we have a series on that too.   In section 1...

CCNA Interfaces

Chapter 1 - Introduction It’s not enough to simply configure a few VLANs on a switch and think you’re done. You also have to know how to connect devices to your switch, and for that matter, how to connect switches to other switches.   So this time we’re looking at interfaces. This includes types of...

CCNA Spanning Tree

Chapter 1 - Introduction It’s not a real big secret that networks don’t like loops. If loops aren’t handled properly, traffic can travel around your network indefinitely, consuming resources.   At layer-3, loop handling is built in. That’s the TTL value in the IP header.   Layer-2 on the other hand, is not so lucky....

CCNA Rapid Spanning Tree

Chapter 1 - Introduction The original spanning-tree protocol was developed way back in the mid-1980’s by Radia Perlman. This is well before switches, as we know them today, even existed.   What you’re seeing here is the original paper published in 1985, outlining how spanning-tree works.   And it worked well for its time. But...

CCNA Etherchannels

Chapter 1 - Introduction When we connect switches together, we need to think about things like… What happens if a link fails? And, do we have enough bandwidth between these switches?   To provide redundancy and increase bandwidth, we’re going to look to a technology called Etherchannels. Chapter 2 - What are Etherchannels? We’ve recently...

CCNA Power over Ethernet

Video: https://youtu.be/-RAPwEMHM58   Chapter 1 - Introduction Got a quick and to-the-point video for you today, and it’s all about power.   Imagine that you have a few desk phones, security cameras and wireless access points to connect to your network. These devices need power, but you don’t want to add an extra wall socket...

CCNA Routing Review

https://youtu.be/PXs8KDFVj1c Study Notes Quizzes and flashcards Transcripts Labs Chapter 1 - Introduction In this section of eight lessons, we’re covering layer-3 technologies. These include IP addressing, routing tables, OSPF, and Quality of Service. We’re starting in this lesson with a review on IP addressing and routing table basics. If you’re already quite comfortable with this,...

CCNA Subnet Design

Chapter 1 - Introduction We’re changing things up in this lesson, and looking at designing the IP space for a network. We’re going to take a fictional network topology, and select suitable IP space for each subnet. Don’t worry, I’ll explain it all step-by-step. This one’s sure to be interesting! Chapter 2 - Design Scenario...

CCNA Dynamic Routing

https://youtu.be/2mLDUvGSutI Labs Transcripts Flash Cards Chapter 1 - Introduction In the last few videos, we’ve only been using static routes. These are fine to a point, but as the network grows, it requires a lot more effort to maintain. Also, static routes don’t respond to changes in the network. So we’re now going to get...
