What do we mean by a single pane of glass?
Ronnie's gonna tell us what that means, so don't go anywhere.
>> You're watching ITProTV.

>> Welcome, and I'm your host Lauren Deal.
And in this episode we're gonna talk to Ronnie about introducing you to
the Cisco DNA Center.
So Ronnie, where is that?
[LAUGH] >> All right, now,
when we start to take a look at this concept of the DNA center, this really is
a change in the terms of configuration and management of our network devices.
So the way that I learned how to do network management was really device by
device, actually configuring each and every one of them by hand.
Well the Cisco DNA Center says look you don't have to do that anymore,
you can actually go to one location.
And Cisco likes to use the term single pane of glass is what they like to to use.
It's a single pane of glass and that gives you complete visibility into the network.
Now, for example, for me, if I were to try and do that manually, right, that means I
have to go to that device, I have to figure out what's wrong with that device.
Then I have to research out what that maybe, and
then maybe drill down again inside and try and figure out what's going on, okay?
The Cisco DNA Center says look you don't have to do that anymore because we
actually have the ability to communicate with these devices and
actually get more visibility than you ever thought that could happen.
So for us the DNA Center is going to be something that you are more than likely,
at least gonna encounter for Cisco exams, if nothing else inside of networks.
But as your network gets larger and become more and more complex,
this gives us the ease of visibility into our networks.
It allows us to ease of configuration by simply plugging in devices,
allowing the DNA Center to find it, and to actually go ahead and configure it and
do what we need to, and begin to monitor and track it as well.
So it's really that one interface that they are so proud of.
This is what they've actually banked everything behind,
is that ability to manage everything.
So Lauren, what do you think?
Let's go ahead and just dive right in and
take a look at what we're actually seeing here.
>> Yes, let's check it out.
>> All right, so on our screen we are actually going to take a look inside.
I'm going ahead and launch this up for us inside the Cisco DNA Center.
Now, what we're taking a look at is probably where most of the people at
the CCNA level are going to be in, which is the idea of what we call assurance.
Now, if I click on this hamburger button in the upper left hand corner,
which is kind of three stacks there.
I don't remember where I picked that up from, that was a while ago,
I'd always thought it was silly, but it kept stuck in my mind here.
At the beginning on the DNA Center, it was really centered around four
different aspects of what we do inside network, design,
implement policy, provisions, and assurance, okay?
Most of the time as a CCNA, you're not designing anything.
You're probably not setting network wide policy.
You're probably not the one that's actually gonna be reprovisioning anything
else, but you're gonna be monitoring.
That's what it comes down to, right?
The ability to see, the ability to point out where things are actually happening,
but not so much at things you might misconfigure and
kind of get a little bit lost in.
So we're gonna take a look inside of assurance, is what we're going to do, and
you can see once I click on assurance, there's multiple different dashboards for
us going all the way down, two sensors, the health, you name it.
You can actually see that there's a lot of different information and
some other analytics down here as well as we start to see.
We're gonna focus in on these dashboards at the beginning, let's select health.
And now we can check out our network devices and
whether they're actually wired or wireless.
So notice over here on the right hand side.
Here are my wired clients, and here are my wireless clients, and
their health right now is about 96% in terms of health.
And when it comes down to wireless clients,
once again about 90% in terms of health and
all of the actual network devices that are also coming across here too.
Now, you can hover over each one of these to essentially give you
the information that you actually are looking at.
And Lauren, we can even go back to the design episode that we're actually going
to end up talking about as well, which is gonna be the idea of routers, core,
excuse me, core distribution and access layer things.
So we'll actually talk about the breakdown of that in network design at the point,
but they're actually going to be listed here on how that's actually done.
We can also view the network help that we choose to.
Notice, we can even see the top 10 issues that my network is currently facing.
So if I'm not sure, if I have a massive gigantic network,
there can be hundreds of problems for all that we know.
But not every single problem is something that would majorly stop us right now.
What we're actually seeing here,
through that single pane of glass that the Cisco DNA Center offers us,
is the top 10 issues that it believes that we need to know about.
So for instance, here, this interface connecting network devices is down.
Also, see a layer 2 symptom, a loop symptom here.
I can see wireless clients failed to actually connect to the AAA server,
you name it.
We can actually see some of that, if I select this one that is priority,
P1 Just as an example, I now can drill down into that particular issue and
find out are there any issues that are open?
Yes, there's two open issues here.
I can even discover what particular building and floor this on and
what layer in the design that actually fits into.
Then we can drill down into the actual specific interface as well.
If I click on this now, I can see that it actually gives me a little bit of
description of what's actually happened here interface, gigabit ethernet one
slash zero slash five connecting to the following connecting the following to
network devices is down and gives me other information that I might need to be able
to trace out and do the other neat thing about this to Lauren is down here.
Okay, it even begins root cause analysis for us so that we can actually go in
to do that and use ai to help us out machine reasoning engine, you name it.
It actually has that ability for
us to see simple things like that about devices inside of our network.
Now with things like that notice that we have, that's overall issues,
I can tell if there's a network issue specifically by selecting network tab
here and the same thing.
Network devices, 82% of them are healthy at this point.
It even shows me which one I might want to focus in on such as the distribution
layer?
I can see that this actually has another score says poor performance according to
the little legend.
Down at the bottom I can see this one actually has a little bit of both.
You name it.
You can actually go ahead and see and select right here and
it draws you down into that.
Specifically if I scroll down, I can continue to see even more
information about the the access points that are actually up and
down and even scroll down to different devices that are actually connected in.
So you name it, if I wanted to see like one particular device,
I'll just select this one here and
in a moment this will actually show up inside of what they call device 3 60.
It will actually go in and find that one single device and
give you details about that device, the issue, the physical neighbor topology,
the path traced, the interfaces that are actually happening here.
The issue that's going on,
you can see where this device is experiencing high memory utilization.
So you have all that and then the neighbor topology,
if you need to trace it down and figure out what's going on,
you know what it's actually connecting to right here in this little diagram as well.
So I can hover and view detailed information if I want you name it,
there's a lot of different issues that are actually happening right here that we
can take a look at clients are essentially users on our network.
So what if I'm actually starting to go?
All right. So what about the idea of clients or
smaller devices here?
We can also see that particular layer.
So down here at the bottom notice I can actually go and find Grace smith.
She's on a Samsung S 10 and I can click on Grace smith and
see what issues Grace smith is actually dealing with as well.
So we have users, we can see the network device,
we can see the overall network if we wanted to.
All that is truly visible when we actually get into this level of what actually
needs to happen.
And lastly here we're actually even able to see the applications that are running
on our network as well and what their health status is going to be.
So you can see right here the 83% of the business relevant applications
are actually healthy.
And also of course there's 18 applications which ones have poor health, I can select,
let's say M.
S. Office 3 65 and
see if I can zoom back out so that we can get away here.
And so now it's actually bringing up that information,
we can see a timeline here of how it's actually performing over time.
I can even scroll down once again into the issues and I can see network latency for
for these applications that are going on as well to be able actually troubleshoot
as we need to.
So when we start taking a look at the D N.
A center we're just showing you that one portion under assurance, but
you do have all these other ones here that are actually available to you to
actually begin your design to begin to set up policy to actually route
traffic the way that you want to as well and even provision devices,
which is actually probably the neatest thing that it does.
You simply buy the devices you plug them into your network.
The Cisco DNA center is running on your network as well and it finds it it goes
ahead and configures it the way that you need to without having to manually
actually even touch device after you plug it in where you think it needs to go.
So this is why the D N A center is kind of the big push from Cisco.
This is the future of network management,
if not even right now that we're seeing less and less.
Are we gonna be going to individual routers and
switches to actually configure it.
Now, having said that right, that's where you're gonna see in medium to large
businesses, Most small businesses, you'll probably still
pull out the console cable still do the configurations manually.
So you still have to actually learn that as well.
But hopefully laura that gives us a little bit of a taste of what we can actually do
inside the Cisco DNA center.
Well that is such a powerful view, it's like looking into the soul of the D.
N. A. Center and seeing all the different options.
So Ronnie, thank thank you so much for showing us what that looks like.
And I hope you take a chance and look at your Cisco DNA center as well.
But we've got more episodes to come.
So don't go anywhere.
Thank you for watching I.
