00:00:00
hey what's up guys welcome to serpros in
00:00:02
this video we're going to be getting
00:00:04
started with probably the most valuable
00:00:06
and important network study tool cisco
00:00:09
packet tracer
00:00:13
[Music]
00:00:21
if you're new here this channel uploads
00:00:23
regular it training videos just like
00:00:25
this one so if you like what you see
00:00:27
here today don't forget to leave a
00:00:29
comment subscribe and give it a thumbs
00:00:31
up
00:00:32
so what is cisco packet tracer packet
00:00:34
tracer is a network simulation tool
00:00:37
designed by cisco that gives you the
00:00:39
ability to go out and build and design
00:00:41
your own computer networks
00:00:44
not only that but it gives you the
00:00:45
ability to visually play with networking
00:00:47
technologies and protocols
00:00:50
it's an incredible study tool and it's
00:00:52
vital if you're taking your cisco ccna
00:00:55
but the best part it's absolutely free
00:00:58
in this video i'm going to show you how
00:00:59
to download install and use this
00:01:01
fantastic tool
00:01:03
so before we do anything we're going to
00:01:05
need to download and install it
00:01:08
to do this we need to navigate to the
00:01:10
cisco networking academy website which
00:01:12
is netacad.com
00:01:15
now if you already have an account with
00:01:17
netacad then go ahead and log in now
00:01:19
otherwise we need to go up to courses at
00:01:21
the top of the screen
00:01:23
then down to packet tracer
00:01:27
cisco has an introduction course to
00:01:29
packet tracer which we need to sign up
00:01:31
for before we can download it
00:01:34
so we need to scroll down here
00:01:36
and where it says intro to packet tracer
00:01:38
click learn more
00:01:41
so here is the course we need to sign up
00:01:42
for but we don't actually have to take
00:01:44
it we simply need to scroll down and
00:01:46
click sign up today
00:01:50
to enrol we need to enter our details
00:01:55
create account
00:02:00
now we've enrolled cisco has sent us an
00:02:02
email to activate our account
00:02:04
so this is the email we receive all we
00:02:07
have to do is click activate account
00:02:12
once we do this it's going to prompt us
00:02:14
to set a password
00:02:17
so we'll just type in a password here
00:02:22
click create my account
00:02:25
so one more step it's going to ask us
00:02:27
for a bit more information
00:02:28
and we'll just fill that out very
00:02:30
quickly
00:02:31
and once we've done click create account
00:02:37
and finally we have our account now from
00:02:40
here we could launch the course
00:02:42
but for now we're just going to close
00:02:43
this box
00:02:46
to download packet tracer we now need to
00:02:48
go up to resources at the top
00:02:51
and then download packet tracer
00:02:55
this will take us to the download page
00:02:57
now if we scroll down
00:03:00
we will see the installation options
00:03:03
so it does support windows ubuntu and
00:03:06
mac os
00:03:07
we're running windows so i'm going to
00:03:09
select the 64-bit downloader
00:03:13
now packet tracer isn't a big
00:03:14
application but it may take a moment
00:03:16
just to download
00:03:19
okay so it's been a minute or two and
00:03:21
our file has downloaded
00:03:23
so we'll just simply double click onto
00:03:25
that file
00:03:27
and start the installation
00:03:32
i'm going to assume you've installed a
00:03:33
program before and essentially it's
00:03:35
going to be a next next next install
00:03:39
again it's not a big program but it will
00:03:41
take a minute to install
00:03:46
and now it's done we'll just click
00:03:48
finish and launch cisco packet tracer
00:03:57
so when packet tracer opens you're gonna
00:03:59
need to sign in it gives you two options
00:04:01
to do this but we're gonna select the
00:04:03
networking academy login which we just
00:04:05
set up
00:04:11
so we'll just sign in with our
00:04:12
credentials
00:04:14
and enter our password
00:04:19
and we're in
00:04:21
so now we have packet tracer installed
00:04:23
and set up
00:04:25
let's take a look around
00:04:26
now don't worry i'm not going to go
00:04:28
through every single menu and every
00:04:30
single feature because i'll bore you
00:04:31
half to death but i will point out some
00:04:34
of the most important features
00:04:36
the first bit we'll look at is the
00:04:38
device menu
00:04:40
down here in the bottom left corner we
00:04:42
have all of the devices that we can use
00:04:44
across the top we have the main
00:04:46
categories
00:04:47
across the bottom we have the
00:04:49
subcategories
00:04:51
and to the right we have the available
00:04:52
devices based on the category we select
00:04:55
there's also a search bar here in the
00:04:57
middle
00:05:00
we currently have the networking devices
00:05:02
selected
00:05:04
under that we have routers switches
00:05:07
hubs
00:05:08
wireless devices
00:05:10
security devices and wide area network
00:05:14
devices as well
00:05:15
the next category is end devices
00:05:18
here we have the normal devices you
00:05:20
would expect like pcs and
00:05:22
laptops
00:05:24
but we also have some iot devices which
00:05:27
can be found under home
00:05:30
small city
00:05:31
and industrial
00:05:32
and power grid
00:05:34
another category that contains iot type
00:05:36
devices is the components category
00:05:40
here you'll find boards leds buttons and
00:05:43
more
00:05:45
now the next category is a very
00:05:46
important one this is the connections
00:05:49
category
00:05:50
this is how we'll connect all of our
00:05:52
devices together
00:05:54
here we have connection types from
00:05:56
straight through cables crossover cables
00:05:58
to coax and serial cables as well
00:06:01
now if you're not sure what type of
00:06:03
cable you should be using don't worry we
00:06:05
also have an auto option as well
00:06:09
now to select a device
00:06:11
we simply choose a category
00:06:14
i'll choose network and devices
00:06:18
and then
00:06:18
routers then we just select the device
00:06:21
and we can drag that onto the workspace
00:06:26
or we can simply click on the device
00:06:29
and then click where we want the device
00:06:31
to be added
00:06:32
that brings us nicely on to the
00:06:34
workspace
00:06:36
this is where we'll be building our
00:06:38
network topologies
00:06:40
we have two options the logical view and
00:06:43
the physical view
00:06:45
what you see now is the logical view
00:06:47
which is where we'll be spending most of
00:06:49
our time but we can change to the
00:06:51
physical view by simply clicking
00:06:53
physical at the top left
00:06:56
the physical view gives us a nice visual
00:06:59
representation of the networks we built
00:07:02
you start off in the intercity view
00:07:05
and we can click down into the home city
00:07:08
even into the corporate office
00:07:10
and even into the wiring closet that we
00:07:12
can see here
00:07:14
and if you look closely we can see the
00:07:16
routers we just added
00:07:19
the buttons at the top right allows us
00:07:21
to navigate through the different levels
00:07:25
this view is great if you want to get a
00:07:27
realistic view of how networks look and
00:07:30
connect together however most of our
00:07:32
time will be spent in the logical view
00:07:35
to go back to the logical view we just
00:07:37
need to go up to logical in the top left
00:07:39
corner
00:07:41
so let's take a quick look at the
00:07:42
toolbar at the top
00:07:44
here we have the select tool for
00:07:46
selecting devices
00:07:49
the inspect tool
00:07:51
which is a way to see basic information
00:07:53
like routing tables quickly and easily
00:07:57
we have the delete tool
00:08:00
the resize tool for resizing shapes
00:08:04
the place note tool so we can add text
00:08:06
to our diagrams
00:08:08
and then we have some drawing tools such
00:08:10
as the line
00:08:12
rectangle ellipse
00:08:14
and free form
00:08:16
the last tools are pdu tools which
00:08:19
allows us to add data to our networks
00:08:21
for quick connectivity tests
00:08:24
okay so that is enough theory let's
00:08:27
delete these routers that we have here
00:08:29
and build our first network
00:08:31
so i'll click and drag
00:08:34
to select the devices
00:08:36
i'm just going to hit delete on the
00:08:37
keyboard
00:08:38
and yes i want to delete my routers
00:08:41
so now we're going to need some devices
00:08:43
and i'm going to start off with some pcs
00:08:45
so i'm going to go down to the end
00:08:47
devices menu
00:08:50
and i'm going to select the pc
00:08:52
and click onto the workspace i'm going
00:08:54
to add another one simply click pc and
00:08:57
again click onto the workspace
00:09:00
now i want to switch to connect these
00:09:02
pcs
00:09:04
so i'll go to network devices
00:09:07
and select switches
00:09:09
now i could select a model here but if
00:09:10
you don't mind which model you can
00:09:12
simply drag from the subcategory onto
00:09:15
the workspace
00:09:17
great now we just need to connect these
00:09:19
devices together to do this we need to
00:09:22
go to the connections menu
00:09:24
and in this case i'm going to be using
00:09:26
straight through copper cables
00:09:30
so i select my pc
00:09:32
choose which interface to connect it to
00:09:35
so this one is going to be fast ethernet
00:09:36
zero
00:09:39
and then select it on the switch as well
00:09:42
again fast ethernet zero slash one
00:09:46
now remember if you don't know which
00:09:48
cable you should be using for the time
00:09:50
being you can simply click the auto tool
00:09:53
click the pc
00:09:54
and then click the switch and it will
00:09:57
automatically select the correct cable
00:09:59
for you
00:10:00
so now we have our devices
00:10:02
what now
00:10:03
well we need to configure them
00:10:06
to do this we just need to single click
00:10:08
on each device so i'll start with pc 0
00:10:11
single click and it's going to open up a
00:10:14
new window
00:10:15
on this screen we get a visual
00:10:17
representation of the device
00:10:19
as you can see here we clearly have a pc
00:10:22
straight out of the 90s complete with
00:10:24
what looks like to be a floppy disk
00:10:26
drive as well
00:10:28
here we can add and remove different
00:10:30
modules
00:10:31
the available modules can be seen here
00:10:33
on the left
00:10:36
if you click on the modules you get a
00:10:37
nice description at the bottom as to
00:10:39
what they do
00:10:41
it's important to note that if you want
00:10:42
to add or remove a module you first need
00:10:45
to power down the device
00:10:48
so for example if i scroll down and i
00:10:50
take this ethernet module and i try to
00:10:53
remove it by simply dragging it to the
00:10:55
left it's going to give me a warning
00:10:56
saying it can't be removed until the
00:10:58
device is powered down
00:11:00
the way you would do that is simply by
00:11:02
clicking the power button
00:11:04
now while this seems like a nice feature
00:11:06
trust me once the novelty wears off this
00:11:09
can get pretty annoying
00:11:11
the next tab we have is the config tab
00:11:14
here we can configure some of the device
00:11:16
settings such as the display name
00:11:18
and some of the interface settings as
00:11:20
well
00:11:21
the desktop tab is where we see all of
00:11:24
the available features for our
00:11:26
pc we have things like the command
00:11:29
prompt the web browser email lots of
00:11:32
things here
00:11:33
but the one we're going to use is the ip
00:11:35
configuration
00:11:38
here we can set the ip address of this
00:11:40
pc
00:11:41
so i'm going to set an ip address of
00:11:42
192.168.0.1
00:11:46
and if we click onto the subject mask it
00:11:48
should auto populate for us
00:11:50
now we have the ip address i'm going to
00:11:52
do the same on the next pc so i'll close
00:11:54
this window down
00:11:56
again single click on pc1
00:11:59
go over to the desktop tab
00:12:01
ipconfiguration
00:12:03
and this time we're going to go
00:12:05
192.168.0.2.
00:12:10
again
00:12:10
auto populate the subnet mask
00:12:14
once we've done that we'll just close
00:12:15
this window down
00:12:17
now we can also configure our switch and
00:12:20
this is really where the magic happens
00:12:22
in cisco packet tracer so if we click on
00:12:24
our switch
00:12:26
we get a new window again we get a nice
00:12:29
physical representation of the device
00:12:31
and any available modules
00:12:34
if we click the config tab
00:12:37
here we can make some quick and simple
00:12:38
configuration changes
00:12:41
we also have the cli tab and this is
00:12:44
where you'll be spending 99 of your time
00:12:47
this is where we interact and configure
00:12:50
our network devices
00:12:51
which at the end of the day is why we're
00:12:54
all here
00:12:55
we'll look at this more as we go forward
00:12:57
i won't dive into this right now
00:13:01
the last thing i want to show you is
00:13:03
probably my favorite feature of packet
00:13:05
tracer
00:13:06
and that is the simulation mode
00:13:10
simulation mode allows us to visually
00:13:12
see messages being sent across the
00:13:14
network
00:13:15
it's really a great tool when learning
00:13:17
how protocols work and behave the button
00:13:20
to enable simulation mode is down here
00:13:22
in the bottom right and we just have to
00:13:24
click simulation
00:13:27
when we turn on simulation mode this new
00:13:30
panel appears
00:13:31
here we can see each event as and when
00:13:33
it happens
00:13:35
by default every available event type is
00:13:38
selected which if you leave them all on
00:13:40
you can quickly start to get overwhelmed
00:13:42
by the number of messages being sent
00:13:45
especially when we start to build bigger
00:13:47
networks so what we want to do instead
00:13:49
is to click the show wall slash none
00:13:52
button to deselect all of those event
00:13:54
types
00:13:56
then if we go to edit filters
00:13:58
we can select which type of event we
00:14:00
want to see
00:14:03
for this example i'm just going to go
00:14:04
ahead and select the icmp message type
00:14:09
once i've selected that i just close
00:14:11
this window
00:14:12
and as we can see only icmp event types
00:14:15
are selected
00:14:17
now we have that selected let's go over
00:14:19
to pc0
00:14:23
and i'm going to open the command prompt
00:14:26
to demonstrate this i'm going to send a
00:14:28
ping to pc1
00:14:30
so i'll type ping
00:14:32
192.168.0.2
00:14:36
which is the ip address of pc1
00:14:39
and i'll press enter
00:14:41
now i'll minimize this
00:14:43
and now we start to see these little
00:14:45
envelopes
00:14:47
these envelopes are the protocol
00:14:48
messages
00:14:49
we can click on the envelopes and get
00:14:51
some information about the message
00:14:54
so on the first screen we get to see
00:14:55
some reference to the osi model but if
00:14:58
we click onto the outbound pdu details
00:15:01
we get to see all of the information
00:15:03
about this message
00:15:05
we can make this bigger
00:15:08
we can see the source ip address
00:15:10
the destination ip address
00:15:12
and then we see the icmp message
00:15:16
this will come in very handy when we
00:15:18
start to look at network protocols and
00:15:20
how they work
00:15:22
we can close this message and then start
00:15:24
to play the scenario through
00:15:27
so we could either hit the play button
00:15:28
in the middle or we can do it step by
00:15:30
step by clicking the forward button
00:15:33
so we can see the message being
00:15:34
forwarded to the switch the switch then
00:15:36
forwarding it to pc1
00:15:38
and we can see pc1's reply
00:15:43
again we can click on these envelopes
00:15:46
and see the information being sent
00:15:48
if we click onto the details
00:15:50
and expand this
00:15:54
we get to see the structure of the frame
00:15:58
note the source ip address is pc1 and
00:16:00
the destination address is now pc0
00:16:04
so this is the beauty of packet tracer
00:16:07
not only can we build our own networks
00:16:09
but we can visually see how those
00:16:11
networks and protocols are behaving
00:16:14
this will really help when it comes to
00:16:16
solidifying these technologies
00:16:18
of course that was a very basic example
00:16:20
of how packet tracer works but you
00:16:22
should now have the tools to go out and
00:16:24
build your own bigger and better
