Hi my name is she had from teach ethics.
Welcome you all to Cisco firewall course.
In this video we will cover the topic of Cisco Packet Tracer which is a free network simulator from
Cisco.
By the end of this video you will be able to understand why we need Cisco packet tracer and how we can
use it to configure our network of course on our training and practicing basis.
So let's start our presentation here.
Here is the official logo of Cisco Packet Tracer
All right.
So as we said it's a network simulator for training purposes as a student you can use it to get familiar
and be familiar with any Cisco commands and as the availability of real Cisco devices to get trained
on is a bit hard actually.
Cisco devices are costly and expensive.
So for training purposes you can actually get actual devices to get trained on.
So for these purposes Cisco invented the Cisco Packet Tracer where you can actually visualize the network
in both logical and physical modes as we will see on reality now on very actual software.
OK.
So how we can get Cisco Packet Tracer simply go to this link which is actually a link on Cisco Web site.
It's called Net CAD or network Academy.
It's part of Cisco Networking Academy
site OK.
Let me show you actually the actual
site here.
This link if you click this link in the presentation you will have this screen.
It will actually tell you how to get Packet Tracer.
It's very easy.
You just enrol to download the packet tracer click on this link.
It will give you another link to participate.
And if for a free video this video actually will teach you how to use Packet Tracer it's free it's a
long video they will teach you how to use their packet tracer.
It's available in English so click sign up today English here you enter your information your name your
e-mail your country gender date of birth and all this and just click Create accounts once you create
your account and download that Cisco Packet Tracer will provide you with a download link
you will have the software up and working just once you click the link on your desktop or the shortcut
on your desktop it will prompt you for user name and password just like any regular software you will
see a screen like this.
This is actually the latest version of Cisco Packet Tracer.
OK which is 7 the two that's one.
This is the latest version you will see a screen like this have logical mode and physical mode the logical
mode that a mode that you need the physical with actually the needed
it's actually for your training purposes it's not needed you have also real time and simulation mode
the simulation with actually I will show you know how to use it let's just see here how we can use it
you have it all networked devices pieces switches routers servers even firewalls.
So let's click on the firewall we have here 5 5 0 5 5 5 0 6 model you just grab it here as a simple
as that if you need a router you grab a router to you choose the modem from here.
Let's say we would take this 1941 model
this which is also grab a switch whatever model you need let's grab this one twenty nine sixty
species you grab a B.S. here.
P.S. Here is also let's grab one set of where he is
OK.
So we grab those devices.
Let's connect him.
It is the connections that click on it.
Mainly what we use in your land is this connection which which is a straight cable.
And this one which is a cross over cable and on the one connections you will use this one which are
actually the Syrian links.
So let's click on this go to P.C. then it will go to the ABC fast ethernet zero you connect it to the
switch the switch have has twenty four ports actually and two Gigabit Ethernet connected say for the
first one in click again the straightforward cable come again on the switch first Ethernet zero over
to connect it to the firewall which has eight gigabit ethernet interfaces plus one management interface
so let's connect it to the first one one over one again click on the straightforward cable click here
we take the Gigabit Ethernet one over two we connect it to the router which has only two gigabit interface
interfaces connected to the first one gigabit zero over zero and then for the last one which is from
the router to the server you will need a cross over cable because that's actually how it has to be from
a server or a P.C. to a router you have to use a cross over cable so let's grab this
connect the Gigabit Ethernet 0 over 1 to the network card on the server which is fast ethernet 0.
All right so here you go.
This is just a simple topology when you see a red sign like this means the interface is down when you
see a green sign like this it means that it's traffic passing and the interface is up OK.
When you see an orange color like this it means the interface is not fully up which means it can be
up physically but it doesn't have an IP address which is down on layer 3 OK on this which you don't
need actually to configure anything since.
Once you connect an interface to the switch it will actually work because on the switch switch this
work on layer 2 so you do need to configure any IP addresses when you come on any device like this point
on it it will show you what interfaces it has what interfaces are up and down here we have Ethernet
0 over one zero over two are up why.
Because they are connected each one to the P.C. and one to the firewall.
That's why they're up also.
Same thing on the firewall when you come.
Just point the mouse cursor on it will show you the Gigabit Ethernet one over one is up this IP address
is given by default 1 9 2 1 6 8 1 that one is given by default it's a default configuration on Cisco
AC all right so that's all for this video on the next view.
We will cover an actual app on configuring the Cisco a as a firewall.
Thank you very much for watching and see you in the next video.
