In the section we are going to talk about Meilan and thinking application in campus networks.
Let's take a look at the overview of Willum first we plan is we're to local area.
As you know and each we learn is one word Testament.
And as we discussed before they pro-white isolation to us villain or Rachel or network works in the
same way as a physical local area network with the exception that the hosts don't need to be located
on the same physical network to be linked.
Segmentation is the division of the network into groups work for Connect unspecified groups with each
other regardless of network affiliation and for isolation of groups for security reasons.
Using a best practice approach to segmentation makes it possible to maximize that use while securing
sensitive data Whelan's can be segmented due to first may be terrific parents.
Secondly traffic types
Daughtry's Geographic group I'm writing wonderful as you can see and the effort is department based.
For example this edge Q of a corporate building and
this is the red and blue line and the gray line.
If I signal the last using the department the pull information read we line users.
Maybe human resources blue maybe I-T and gray may be the finance
internet or design and network administrator can design a campus network with one of two modules.
The first one is local Freelon.
The second one is an to and Walen in the local Mudgal the local So which is connected to a distribution
or core switch.
This is where the routing is performed actually local Rylance will all the exits.
But when the local access sewage and the distribution or course which in this model you use different
Whelan's for different geographical regions for example as you can see that in the picture we have accounting
Whelan that's reliant on for this location but for another location we are using we land 30 for the
accounting for example engineering using we land to anyone here.
And then we land 40 in other location of the cardboard building.
And then Whelan's are dispersed throughout the network on multiple Swades no matter where the user plugs.
And they will always be assigned the same wheel and membership resources for this user will be on the
same subnet management of and temp villans typically used v.t. to trunked soulmates.
And this allows for easier management and you can see that in the picture again this building may be
in Paris and the other building may be in Amsterdam and here maybe where €30
and if I is a real one for enginering in here and Villon through is I the and when I'm through is finals
in Parus they are going to be same for Amsterdam and Tokyo to
and let's take a look to the voice real and concept.
Now usually I sit next to a computer on the same desk.
They record the same you pick cables as computers use and they use internet if you want to connect them
to us which we usually use the method in the picture as you can see.
You probably want to separate words and they are terrific.
And this is something we can do with voice Whelan's as you can see that in our figure just one cable
is coming to the IP phone and IP phone has two parts the first part is the local area network port which
with Plack actually this cable coming from Savage and the other port is connected to PC and that part
is known as the PC PARC and we are using different villans to carry data and what's terrific in this
example we are using we learn thoroughly and will antenne will unthawed is carrying the worst traffic
and then carrying the PC data.
And here is the conflagrations steps.
For example if we are using Fester's 0 or 16 port
we are going to the interface more by typing interface known and 0 16 and we are tapping the access
port switchboard access real content and we are defining the PC data and we're using the switch port
voice mealand command and riding the worst we land as well.
Let's take a look to the wheel and truanting think again as we talk in our pervious sections.
An access port can Terry just when we land and transports can carry multiple wheelers we can use real
and wandered and just rely on 200 for these two ports.
But this guy can carry both of
here's the configuration steps of the villains.
First we are creating the realigns and the configuration Maat for example on one.
And we can define a name.
This is arbitrary.
And we are defining We 200.
And the name of it to them we are going to the under interface Mauch by typing interface.
Take 0 for example which is this part
we are defining it to the access point by typing.
So we put more access and we are making the villain configuration by typing switchboard access.
We learn and will a number if we want to configure it transport.
We are going under the interface mode.
Again and we are typing switch you're drunk and and encapsulation portico which is about like you for
now.
And we are defining the transport by typing port.
Not to rank and we are defining the villains that we want to carry from this tronk and that's it we
can use to try and link protocols when we want to implement trunking and they are I s.l and that one.
Q I sell as a Cisco property tracking protocol which provides tracking for us and top line.
Q Is an industry standard protocol.
Q Has less framework than ISIL and as a result that one is more effective than s.l especially in small
frame's when that one queue load is 4 bytes.
I hersel is 30 by let's take a look to that my Cuneta real and concept.
Normally a transport can send and receive that one Curiel intact into Italy and France if the switch
receives an antique from Antec frame from the transport.
These friends are forward to another reland configured as the native willat the native realize that
when the true difference which must be say otherwise the native Melanne mismatch warning is taken and
Cisco uses Cisco the skurried protocol CTP when doing this.
And please keep in mind that the fall they too will learn is what here is how we can configure a trunk.
We are going under the interface Maut and we are typing the and Cupps lation protocol and we are using
to switch Portmore trunk and this line is actually optional.
We can define it if we can define that better.
But if not all other religions will go from the transport to a fire transport.
We are using show interfaces and the interface name and the switchboard.
Actually we are seeing that the Edmond's through Maut which means what we configured for this port and
the operational mode which means what this port is actually behaving right now.
Is it trunk or is there a problem.
We can't see by using this comment and the other comment that we can verify the trunk port is show interface's
trunk which shows us the interfaces making actual trunking.
At that moment to us and let's take a look to the dynamic trecking trying per local DTP DTP.
Is this Cisco purportedly working Pearla code up by Cisco Systems for the purpose of negotiating trunking
on a link between two villaine wear sweats and for negotiating the type of tracking encapsulation to
be used.
It works on late 2 of the OSA module and we untransformed using DTP may utilize either.
I believe that one Q or Cisco myself in repeat the following switch Portmore settings exists.
And their access
trunk dynamic outhaul and dynamic.
This will that would be better to underline this guy's
dynamic other than this about trying and access access puts the Internet port into permanent non-throwing
mode and negotiates to convert the link into and not try and link the Internet port becomes a non transport.
Even if the neighboring port does not agree to the change.
Trunk puts the Internet port into permanent trunking mode and negotiates to convert the link into the
trunk link the port becomes a transport even if the neighboring port does not agree to the change the
dynamic auto makes the Internet port willing to call to link to a trunk link.
The port becomes a trunk port.
If the neighboring port is set to trank or dynamic boat mode.
This is the default mode for all Internet ports.
And lastly Barragan talk about dynamic desirable which makes the port actively attempt to compare two
linked to the trunk link.
The port becomes a transport.
If the neighboring Internet port is set to trunk dynamic servo or dynamic auto mode and here are the
best practices of the real NS and tracking.
First we need to work using we learn when to write security issues because Villon one is the default
Vila set count.
We need to configure track ports manually.
Long use DTP place you can face with big problems if you use DTP actually.
And third we need to use that key instead of SL.
We need to use S-sh instead of not for remote connections because S-sh news anchor option for the connection
and we need to make the native willen different from real man to prove our DTP spoofing.
