Transcripts
welcome to my complete practical CCNA course this course is very different to other courses
I'm going to be explaining CCNA topics using physical equipment rather than simulations or
emulators I've heard this story too many times new person arrives at site they need to configure a
device and they ask where is the device and the customer is shocked because the device is right
next to them and that's because the person is only ever used simulations or online labs and doesn't
actually know what devices look like it's really important that you see what the physical devices
actually look like and how they act rather than just using a simulator or even an emulator like
CML I've spent thousands of dollars collecting various devices to add to this course and this is
only some of them as an example here's a starlink mini this really changes the game because you can
access the internet using a portable satellite dish like this this has a built-in router and
I'm going to explain what a router actually is because you need to know the differences between
say routers such as these or some of these routers versus what a switch is and what a layer two and a
layer three switch is you may not understand what those terms are right now but in this video and
in the course I'm going to explain those topics in a lot of detail and you're going to configure
CSCO routers and switches so that you have the knowledge to pass the CCNA exam but also have
the knowledge to go out there and be successful in your career now Packet Tracer and CML or Cisco
Modeling Labs are fantastic for labs and you can use those as part of this course but they cannot
simulate physical devices like these Fiber Optic Cables you need to know the difference between a
single mode fiber optic cable and a multi mode fiber optic cable notice the difference in
the light shown through these cables single mode fiber if I bend it you can see the light bleeding
through the cable there but notice the pattern doesn't really change whereas with multimode fiber
if I bend the cable the pattern changes it moves you need to understand the difference
between multimode and single mode fiber very difficult to understand that and Visually see
what it does when you're just using an emulator now you may be wondering why do you need to know
about fiber cables you're actually using them right now the world is connected using fiber
cables under the oceans so when you're watching a YouTube video as an example that information
is transmitted across a fiber cable such as these we also have copper ethernet cables so
this is a copper ethernet cable that you probably seen before it's using an RJ45 connector at the
end here this uses copper this is fiber data is transmitted through light through these cables
whereas here it uses electricity to transmit data now in the CCNA course you're going to learn about
an Ethernet Bridge specifically in Spanning Tree you're going to learn about something called the
Spanning Tree root Bridge most people will just show you a picture of a bridge they will not
show you what it actually looks like so they'll use an icon and we've actually designed brand
new icons for this course so all the topologies are going to be using a new icon set that we've
created so you'll just see an icon similar to what's on screen at the moment but you don't
know what a bridge actually looks like and how it actually acts now I do get some push back or flack
when I show older devices but a really important lesson in networking if you don't understand the
past you won't understand why things act the way they do today like as an example
if you don't know what a bridge is you wouldn't understand why we have a root Bridge rather
than a root switch in spanning tree you wouldn't understand why a switch and this is a very modern
switch this is a 9200 CX switch why modern switch like that is better than a bridge or
even an older switch like this 2950 series switch switches are much faster than Bridges but they act
in a very similar way in the very old days we had interfaces like these these are serial interfaces
very very slowly you may still come across them depending where you are in the world so
I'm going to talk about some of the history as we go through this course so that you understand
concepts such as a collision domain or broadcast domain collision domains were really important
when we had hubs notice this is a Cisco Hub this is a hub this is a switch they're very
different a hub as an example works as follows when traffic arrives in one port it's repeated
out of all the other ports this is known as a multi-port repeater here's an example of a
single port repeater we've only got port Port one and Port two here so when traffic arrives in one
port it gets repeated or amplified out of another port that allows ethernet to traverse much greater
distances so as an example with the cables that we tend to use today UTP cabling a cable like this
as an example maximum distance is 100 meters if you wanted to amplify the signal or have the signal go
further you need something that repeats the signal or amplifies the signal and this is a very basic
example of a repeater multiport repeater or Hub is a dumb device doesn't understand the traffic sent
in the network so when traffic arrives on one port destined to one other device simply replicated or
repeated out of all other ports on the device that means that if you have a collision on any one of
these ports it affects everyone in the topology switches work differently to Hubs so in switches
we use what are called Mac addresses or Hardware addresses to identify hosts on a network so when
you use your phone as an example to connect to a Wi-Fi network or you use your computer
to connect to a physical ethernet Network you'll notice that it has what's called a MAC address or
media Access Control address that is a hardware identifier for a device on a ethernet Network or
a Wi-Fi network your device will also have an IP address here we've got both an IPv4
as well as an IPv6 address in networks today and the internet today we use IPv4
or IPv6 those are protocols or languages if you like here we speaking English hopefully you
can understand what I'm saying because speaking the same language when a phone as an example is
used to go to YouTube the language used by the phone to send information into the network and
for YouTube to send a video back to the phone is IPv4 4 or IPv6 now I've invested
thousands of dollars collecting equipment for this course and this is only some of it not only
collect equipment that you might never have seen before such as this ethernet Bridge or the Cisco
Hub but I've also collected very modern devices to add to the course such as this C 9200 L switch
and one of my favorites the c9200 CX switch I like these small switches such as the 1000
series switch because they're quiet and I can run them on my desk without a bunch of fan noise but
I have got bigger switches such as this one I've also got a Cisco 8200 router or what Cisco call
an edge platform but it's essentially a router so I've got a very modern router here I've also got
another modern router here on ISR 1100 4G as well as these 1000 series routers so I've got these two
routers that have multiple ethernet ports and this one has a DSL Port as an example I've also got a
Cisco firewall as well as a Cisco land controller and I've collected a whole bunch of access points
so that I can physically demonstrate how things work now what is a router Router basically route
from one network to another you may have a router similar to this at home one of the most confusing
things about devices today is that they actually combine various features together so even though
this is a router it actually acts like a Wi-Fi access point in other words you can connect to
the router using Wi-Fi here has a dedicated Wi-Fi access point as an example this isn't
a router it's simply an access point allowing you to connect to the network using a Wi-Fi
device so this acts like a Wi-Fi access point it acts like a switch so it has what I called
Lan ports but notice it also has a Wan Port these are local area network ports local area network
is a network like in your home it's local to where you are routers route from one network to another
using the W or wide area network so as an example you could use ethernet like on this router but
here's a 5G router this routes from your home to a 5G Network here's a starlink router routes from
your home network as an example to satellites and onto the internet there is a DSL connection this
routes from your home network so perhaps you've got some devices connected to these ports at home
connects you via your telephone to the internet or wide area network so a router will rout you
for instance from ethernet your local area network or Wi-Fi to satellite or from ethernet your landan
interface or your local network to 5G or 4G or if you've got fiber at home you might have
an ethernet port on your router that connects you to a modem or a device that your internet
service provider or ISP gives you at home with a fiber connection again I'm hoping that this is the
most complete most practical and most real world CCNA course that you take that you're not just
learning about stuff from a theoretical point of view that you're actually seeing what these
are these are sfps so we've got 10 gig sfps here we've got gig sfps here's a 25 gig Dack cable or
direct attach cable and here we've got 100 gbits per second qsfp28 I don't want you to go out into
the real world and only learn about stuff through slides or through pictures I want you to actually
see how things work and not just old equipment but very modern equipment as well now for the
labs you could use packet tracer this is a Cisco 4321 router and the reason I purchased this router
is because it's part of Packet Tracer so in the labs I will show you physically how things look
and then you'll be able to configure them Packet Tracer is a fantastic simulator but it doesn't
simulate everything perfectly 950 switches are also part of Packet Tracer but again I've got very
modern switches like the c9200 CX fantastic little switch it's important that you understand the
difference between a classic iOS switch as well as a iOS XE switch so I've got both examples here
so that you can see how iOS XE versus iOS Works basically iOS is the operating system that devices
run so it think of this like running Windows or Mac OS so you're running a Windows operating
system on your PC this device runs Cisco iOS this device runs Cisco iOS XE so you need to learn the
commands that the operating system uses in the same way that you'd learn commands in Windows
or Linux or Mac OS and that gets to me talking about PCS that are part of the lab I'm going
to show you Mac OS I'm going to show you Linux I'm going to show you Windows physical laptops
that are connected to the devices so that you understand how things actually work versus what
simulated environments do so as an example if I had this MacBook connected to Port one on
the switch and this Windows computer connected to Port two on the switch if traffic was sent
from the MacBook to the Windows computer traffic would arrive on Port one and only go out of port
two because the switch would learn where the Mac addresses are of the devices in the topology with
a hub however if the MacBook was connected to Port one again and the Windows computer is connected
to Port two if traffic was sent from the MacBook to the Windows computer it would go out of every
port except the port in which it arrived because the Hub is basically a dumb device it doesn't
understand where devices are in the topology it doesn't Lear Mac addresses it it simply repeats
or floods the traffic out of all ports except the port in which it arrived hence it's called
a multi-port repeater we don't really use hubs today but the reason why it's important to know
about them is you need to understand collisions in Ethernet networks Wi-Fi as an example is a
shared medium so the bandwidth is shared between multiple devices in the same way that it it is
with a hub I've used a lot of terminology now don't let it overwhelm you we're going to talk
about what this means and why it's important I'm going to show you how these physically get
inserted into switches such as these and how they used with fiber cables as an example don't let
the terminology worry you if you struggle just know that you're joining many of us who started
initially and it felt like we were drinking from a fire hydron because there's so much information
just keep on trying to learn something new every day and you'll get it networking initially seems
really complicated because of all the terminology some people have told me that they find it really
abstract it's difficult to imagine things or to conceptualize things and hence me buying
once again lots of physical devices and cables and options to show you how things actually work
both for the CCNA but also for the real world big thing that I suggest you do is download Packet
Tracer it's free software that you can download from Cisco and you can practice so in the labs
you can either use Cisco packet Tracer or CML Cisco modeling Labs but if you're new to this
and you're struggling get Cisco Packet Tracer and I'll show you in an upcoming video how to download
that and install it and build your own networks using Cisco Packet Tracer once you've seen real
devices working you'll find it a lot easier to work with Cisco Packet Tracer and configure
networks yourself okay I hope you are as excited as I am to release this free course on YouTube
