In this lecture I will give a brief introduction of our a city soldier any story or graphical network
simulator e.g. software solution that allows you to design complex network to villages and in 180 score
and other Windows devices.
It is free and open source software that is used merely to study for certifications such as DNA CMB
or even TCE and it can be used to test network designs and configurations so the first decision we have
to make after installing Janus 3 is to select how we will run it using the set of wizard running VNS
3 on the local server will allow you to configure basic Cisco to villages but if you want to configure
more advanced technologies such as ones that include Cisco say firewalls I owe you L2 which is related
to IAW on Unix and other options.
You need to use the Janus 3 VM which is a VM that is free to download and you can run everything on
it and whichever that can be shared with multiple users after that they have the option to use it simulate
a billions file which is a very configured template that you can download from the Janus 3 website to
make the inboard process of the appliance very simple.
You have to know though that the template does not include the applicant's image so you have to get
that severity or we can manually select and configure the device type including I always devices IOU
devices and other types so we will select the manual configuration of I always device that requires
that you have gotten the respected IOUs already by downloading it or copying it from your outer and
generally does not support all Iowa's images.
So you have to search to find if the OS you intend to use he supported or not.
And to emulate to choose.
We have choices such as using the built in switch that have very basic switching capabilities so it
just provides connectivity and wheel and ranking with a symbol.
Goofy but no Seelye but in our case because we have to deal with more advanced options and demonstrate
attacks on switching features that we can show using CLIA comments we have to use more advanced options
such as the ether switch would you which easy.
Sixteen boards would you.
That can be inserted into a slot of some routers such as the twenty six hundred thirty six hundred and
thirty seven hundred series routers Another option is using the Cisco high OS v L2 which is the best
or the recommended way for using switching in June a 3 We can also use I owe you L2 which is also a
good option and both I always feel L2 and I owe you L2 require using the Janus 3 VM and you can insert
different types of network modules into slots that you can change later from the references or after
dragging the device into the workspace and edit or configure its settings and you can eat it.
Other things also including the BIOS image and ideal B.C. value and so on and seating the ideal value
will you get your computer into sleep every few milliseconds so that CB you consumption is reduced.
So in this picture.
I have given a brief introduction about Janus 3 and in the next picture we will start our hands on practice
with G and a 3 by downloading and installing it.
