Let us perform the lap task.
So I want to make this particular review very clear that you understand what is meaning of host what
is meaning of physical interface.
What is the virtual our VM interface.
So suppose I have a one host in this case we have host to one and host two.
Now here we should understand algo and log in and I'll show you all those things.
Now inside this host feel of the interfaces will be physical differences.
I'll mark this as a physical.
We'll see both the host.
They have the indivisible physical interfaces.
We'll see that what is the physical interfaces and these guys they have there.
We switch and these guys they have their TV is no devious will be common for all the host.
Correct.
And that's the use of devious devious having global view for all the host and the networking.
But these host they may have their local switch.
So we use if for example we as Europeans you know again where we are going to use the port groups where
we are going to the port group that is also very important to let let us understand all these things.
So let me go to the host and cluster inside the host and cluster.
If I go let me walking on this thing so I am inside the host one and if I go and click a So for example
we have configured so first of all let's start with configuration inside configuration you can see you
have the networking tab here inside networking you have virtual switch.
So what type of search I have inside the E6 I are the host virtual switch VM Colonel adapter physical
adapter and DCP IP configuration.
Now this VM colonel let up Derek think this is related to control plane traffic control plane traffic
this physical adapter that is going outside this is nothing back to uplink correct controlled plane
traffic it is going outside like that you get you have to think now.
So you have the host you have the control plane adapters you have the uplink and then you have the virtual
switch where you are connecting your VM interfaces are VM Nick are generally we are telling we nick
you see we have one diagram we'll check back so we nick watch Alex we are in the end we have our Chile
we are connecting with the world.
Virtual switch now this switch this virtual switch maybe a standard switch or maybe distributed virtual
switch.
Correct.
So let me go and show you that so I will go here and click virtual switch once I click that you can
see here inside the virtual switch you have two category of switch one category is this a distributed
virtual distributed virtual switch.
The category is stranglers which together we switch now under top we have the option we can add network
and add those switches we will see like run by two because this particular section is focused on we
switch is which we will explore on that.
But suppose if I go and click this distributed switch let me expand this.
Here you can see that this particular virtual switch is connected with different different type of network
interfaces.
So we have the ASX a reason is just a name belonging to William kernel is not attached to any VM.
So you have different different networking and these networking interfaces you can think these networking
interfaces.
Nothing worked as a port group.
So here you can see that you have one of the port group that is nothing but a VM reason really is this
just a name it attached with one of the virtual machine that is Windows 10 correct.
Now here you can see clearly that this Windows machine.
This is a part of Port group are the networking they have their Winik is connected here that is spin
towards two uplink.
Now these uplinks can do the Nick teaming load balancing et cetera et cetera.
So many features that we can achieve with the grouping of uplink but this uplink that is inside one
of the group one of the networking they're part of uplink reason 0 1 network.
So you have one two three four and five different type of network inside this particular distributed
virtual switch.
And the name of this particular distributed virtual switch is nothing.
The reason is the row with the desktop.
So before showing this section that is this kind of switch I want to show you one very important thing.
So if I go ahead and click networking either you can go and click there or you can go to the menu and
you have this networking.
Either way is fine.
So once you are inside the networking you can see here that you have the switch.
This is the day a switch inside that you have the groups.
Right.
So inside that you can see that you have different different network.
This is a one way to see this.
You can see distributed switch.
This is actually the port group network.
You have some uplink to uplink having to host.
This is actually this is the switch.
And this particular switch is combined are can be combined with multiple hosts are the E6.
Correct.
Now let's go back we'll go to the cluster here and inside the host.
Again I want to show you some other things.
So suppose I'm jumping ahead of the time.
Suppose in this place if I go and click network you can see here the network.
So you can see you have the network distributed port which becomes a distributed port group.
Then you have uplink port.
Group then you have the standard network will see this also or does it belong to one of the VM is part
of this particular standard network.
This is actually belonging to our switch our standard switch that we have distributed port.
You've distributed to you.
So you have port groups you have uplink port group and one VM network is there.
This also I can think as a port group at the moment it's like this.
Now before moving further let's quickly go and check the V switch because I'm very much interested in
the research.
I'll go to host configuration and the research and let's see the Iskander visits.
So now you have on a of research you can see one uplink and one of the VM Winnick.
So when we Winnick connected with one uplink This is nothing but tiny Linux.
Correct.
Now if you want to see more detail about this you can go and check the MAC address.
I have to type.
You can go and check the properties related to that.
All these properties will discuss in the upcoming section.
But what are the things you can do with the standards which now you can put the security features like
promiscuous MAC address changes for phones transmit by default you can see these are the default settings
traffic shaping option we can do we have the NIC teaming at the moment the only one Nic is there.
So I will not do any load balancing type of thing or teaming type of thing correct.
So here you can clearly see that do you think that you have your host on say this is my host to one
say host one at me right.
Take two one more time.
HOST When this host having DV is but this has a v switch as well.
Now this we switch and obviously you have the VM Well one of the VM.
That name is Tiny Linux one of the VM port that is nothing but to Nick is connected with degrees which
is zero and this V switch is zero you can see that they are tied with one of the uplink as well the
uplink is nothing but we m Nick to okay.
So first of all let's see that this particular guy this particular host one having how many uplinks.
So if you want to see this you have to go here to the physical adapter you can see that it has 0 1 2
and 3.
This too is connected with this particular axis which for the moment I give the name as the axis switch.
So this is a standard switcher axis which frequency but two other Nicks for example the physical link
say we m Nick zero and the M Nic one they are connected with these devious.
So they are connected devious but they still I have one week that is called We m Nic three that is not
assigned any anyway so whatever you do I'll go and attach this guy here okay so let's do this operation
I'll go and attach this leftover Billick to the scanner switch and then we can do certain operations
correct but at the moment I think that you are able to understand that how this local switching or how
the access or the standard switch and is working correct.
So here you can see have this option of had the network like I'll go to this switch if I am hearing
the virtual switch I can click ad network when you're adding the network again you can see now we are
going in-depth again you can see you have option to create William kernel network adapter that is related
to control graphics such as a v motion I use the interface if C wi fi tolerance we use reason and whose
management other thing you have the virtual machine port grew for a standard switch you have a physical
network adapter because I am focused on virtual switch so one thing I'll use this.
Now suppose if you want to create a new scandal switch you have option here that you can use the existing
so I can go and use this guy we switch 0.
That is my existing switch and then I'll go next.
Now the network labeled I leave this as default I leave this will an idea as default I'll click Next
ready to complete finis.
Now you can see first of all what I have shown you here is that I simply went on and added the extra
network here.
So I have either TV network and then VM network to.
This is nothing but a local port group you can think this is a local port group looking through this
particular visit.
So once I have created this
then what I will do here.
So now we have two port group local port Look I can go to the tiny Linux here if you go here you can
go ahead and you can click do right click here or you can go to the configure also so tiny Linux and
configure I think and configure all say should get the option related to
to at the VM but we are not getting it here.
Configuration never mind you have multiple ways to do the same thing.
What we can do here.
Let me check action I'll see if I get you.
So you can do like this you can go to the action you can click a good second are you can do right click
here you can go to the edit settings and now if you see here browse you can see your VM network too
has been created you can add this so this is what we have done.
Now let me go back to the network first of all.
Now you can see that it is connected with network too.
So let me go back one more time because I want to add to a network.
So for that term what you can do hear that.
OK I'll roll back to VM network first this with a local switch and then add new device.
Let me add one more.
Oh one more network adapter and this network adapter.
This time I will add network number two.
Okay so now what is happening.
We can go and check the task as well.
So we have successfully added extra network.
Now when we are talking about these networks even we'll see later on not with the kind of switch because
we are not going to do much things in the Iskandar.
With respect to his strange message.
Whenever we see the production networking will find a widely distributed virtual switch and those are
heavily used.
So I'm not stretching much inside this but still you can see that you can go and add these kind of networks
so if I go down here you can see that now inside that we have to network here.
What about adding physical network adapter.
So let me go and add the physical adapter as well.
And so let's do this.
I'll go to the physical adapter I have one of the fiscal year after that is unused.
I can click this.
I can click edit
and let's see it.
I can simply change the speed and neural expert.
I know one thing.
I had the network physical adapter its active physical adapter now and do physical adapter with the
existing switch I have this V switch.
OK.
I'll go next.
I have this.
Let's click if I have any unused yes.
So I want to ask this really.
3 There.
So now you'll see initially in that research we have one uplink.
Now you have added one more uplink.
And here's the trick.
So what you want do you want active a standby.
Are you want active active like this.
We can see all the properties are we want to do that and use.
So for example I want active active then you can see you have all sorts of properties here CTP LDP all
these options we have will check this later on but I can go next year finish.
So once I finish this now you can see these two physical interfaces part of obvious which I'll go quickly
back to the switch and inside a switch you can see now you have two you can see clearly see that how
I have added the V-neck Winick what's your leg and then added one interface inside the VM machine and
both the interfaces you can see here they are part of the Nichol support group and then the board group
related to physical in different parts the physical interface use as active active you have option you
can use this as the activist can be as well you can go and check the settings so I hope you understand
how we can do the operations related to networking now on the top you can see manage fiscal adapters
at the networking so from here also you have the option so multiple options you have when you're adding
the VM kernel for this particular switch so that option also you have existing is switch if you're adding
the VM Colonel VM Colonel name what is the IP for Aggies what's the use of this is the emotion or whatever
is the management interface opportunity IP for Agnes automatically or you have any ideas that you want
to put you have any subnet mask key you want to put you have a default yet when I am just showing it
for an example so entered a valid subnet mask so I do one thing.
If 24
do this thing when I use this notation but it is not telling you that in which format you have to put
a sticker and finish this will fail because this is the wrong address and all but let's see which error
we are getting to.
We can go and check the alarm and see where it says a lot what errors we are getting adding this particular
VM cannot like occurred during host configuration and we have error because that IP is not existing
and the other is just what I am just showing you that from here also you can add if you want to edit
anything you can go and do the aged.
So with respect to this which I can go and change the properties I can go and change the security setting
like macro messengers forwards transmit.
We'll see all these things later on.
What does mean.
What is the overall.
So for example use of this other their definition of this will see in the upcoming slides load balancing
method you can see you have plenty of load balancing method like IP based macros virtual port etc fallback
notify and the failover order then if you want to click manage you can do up and down.
So this is actually all the operations related to local switch and this actually we are not using much
but it's good that we understand that how we can add delete change modify etc etc. So how we are doing
a number of operations related to this but our more focus will be on the distributed virtual switch.
So lets just drop here an upcoming section will again learn more about these virtual networking.
