1
00:00:00,000 --> 00:00:03,242
What do we mean by a single pane of glass?

2
00:00:03,242 --> 00:00:05,614
Ronnie's gonna tell us what that means, so don't go anywhere.

3
00:00:05,614 --> 00:00:08,258
>> You're watching ITProTV.

4
00:00:08,258 --> 00:00:11,448
[MUSIC]

5
00:00:11,448 --> 00:00:14,712
[BLANK_AUDIO]

6
00:00:14,712 --> 00:00:17,293
>> Welcome, and I'm your host Lauren Deal.

7
00:00:17,293 --> 00:00:20,571
And in this episode we're gonna talk to Ronnie about introducing you to

8
00:00:20,571 --> 00:00:21,617
the Cisco DNA Center.

9
00:00:21,617 --> 00:00:23,936
So Ronnie, where is that?

10
00:00:23,936 --> 00:00:25,792
[LAUGH] >> All right, now,

11
00:00:25,792 --> 00:00:29,365
when we start to take a look at this concept of the DNA center, this really is

12
00:00:29,365 --> 00:00:33,133
a change in the terms of configuration and management of our network devices.

13
00:00:33,133 --> 00:00:37,799
So the way that I learned how to do network management was really device by

14
00:00:37,799 --> 00:00:42,100
device, actually configuring each and every one of them by hand.

15
00:00:42,100 --> 00:00:45,326
Well the Cisco DNA Center says look you don't have to do that anymore,

16
00:00:45,326 --> 00:00:47,029
you can actually go to one location.

17
00:00:47,029 --> 00:00:51,778
And Cisco likes to use the term single pane of glass is what they like to to use.

18
00:00:51,778 --> 00:00:56,858
It's a single pane of glass and that gives you complete visibility into the network.

19
00:00:56,858 --> 00:01:00,145
Now, for example, for me, if I were to try and do that manually, right, that means I

20
00:01:00,145 --> 00:01:03,182
have to go to that device, I have to figure out what's wrong with that device.

21
00:01:03,182 --> 00:01:05,640
Then I have to research out what that maybe, and

22
00:01:05,640 --> 00:01:09,894
then maybe drill down again inside and try and figure out what's going on, okay?

23
00:01:09,894 --> 00:01:13,594
The Cisco DNA Center says look you don't have to do that anymore because we

24
00:01:13,594 --> 00:01:16,818
actually have the ability to communicate with these devices and

25
00:01:16,818 --> 00:01:20,415
actually get more visibility than you ever thought that could happen.

26
00:01:20,415 --> 00:01:25,178
So for us the DNA Center is going to be something that you are more than likely,

27
00:01:25,178 --> 00:01:30,112
at least gonna encounter for Cisco exams, if nothing else inside of networks.

28
00:01:30,112 --> 00:01:34,044
But as your network gets larger and become more and more complex,

29
00:01:34,044 --> 00:01:37,419
this gives us the ease of visibility into our networks.

30
00:01:37,419 --> 00:01:40,620
It allows us to ease of configuration by simply plugging in devices,

31
00:01:40,620 --> 00:01:44,314
allowing the DNA Center to find it, and to actually go ahead and configure it and

32
00:01:44,314 --> 00:01:47,154
do what we need to, and begin to monitor and track it as well.

33
00:01:47,154 --> 00:01:50,329
So it's really that one interface that they are so proud of.

34
00:01:50,329 --> 00:01:53,669
This is what they've actually banked everything behind,

35
00:01:53,669 --> 00:01:55,881
is that ability to manage everything.

36
00:01:55,881 --> 00:01:57,158
So Lauren, what do you think?

37
00:01:57,158 --> 00:01:57,999
Let's go ahead and just dive right in and

38
00:01:57,999 --> 00:01:59,023
take a look at what we're actually seeing here.

39
00:01:59,023 --> 00:02:00,819
>> Yes, let's check it out.

40
00:02:00,819 --> 00:02:04,626
>> All right, so on our screen we are actually going to take a look inside.

41
00:02:04,626 --> 00:02:09,887
I'm going ahead and launch this up for us inside the Cisco DNA Center.

42
00:02:09,887 --> 00:02:13,891
Now, what we're taking a look at is probably where most of the people at

43
00:02:13,891 --> 00:02:18,248
the CCNA level are going to be in, which is the idea of what we call assurance.

44
00:02:18,248 --> 00:02:21,548
Now, if I click on this hamburger button in the upper left hand corner,

45
00:02:21,548 --> 00:02:23,253
which is kind of three stacks there.

46
00:02:23,253 --> 00:02:26,402
I don't remember where I picked that up from, that was a while ago,

47
00:02:26,402 --> 00:02:29,567
I'd always thought it was silly, but it kept stuck in my mind here.

48
00:02:29,567 --> 00:02:34,492
At the beginning on the DNA Center, it was really centered around four

49
00:02:34,492 --> 00:02:38,585
different aspects of what we do inside network, design,

50
00:02:38,585 --> 00:02:42,692
implement policy, provisions, and assurance, okay?

51
00:02:42,692 --> 00:02:48,684
Most of the time as a CCNA, you're not designing anything.

52
00:02:48,684 --> 00:02:51,495
You're probably not setting network wide policy.

53
00:02:51,495 --> 00:02:55,575
You're probably not the one that's actually gonna be reprovisioning anything

54
00:02:55,575 --> 00:02:57,680
else, but you're gonna be monitoring.

55
00:02:57,680 --> 00:02:59,034
That's what it comes down to, right?

56
00:02:59,034 --> 00:03:03,311
The ability to see, the ability to point out where things are actually happening,

57
00:03:03,311 --> 00:03:05,938
but not so much at things you might misconfigure and

58
00:03:05,938 --> 00:03:07,604
kind of get a little bit lost in.

59
00:03:07,604 --> 00:03:11,505
So we're gonna take a look inside of assurance, is what we're going to do, and

60
00:03:11,505 --> 00:03:15,584
you can see once I click on assurance, there's multiple different dashboards for

61
00:03:15,584 --> 00:03:18,864
us going all the way down, two sensors, the health, you name it.

62
00:03:18,864 --> 00:03:22,576
You can actually see that there's a lot of different information and

63
00:03:22,576 --> 00:03:25,655
some other analytics down here as well as we start to see.

64
00:03:25,655 --> 00:03:30,873
We're gonna focus in on these dashboards at the beginning, let's select health.

65
00:03:30,873 --> 00:03:34,011
And now we can check out our network devices and

66
00:03:34,011 --> 00:03:37,244
whether they're actually wired or wireless.

67
00:03:37,244 --> 00:03:39,020
So notice over here on the right hand side.

68
00:03:39,020 --> 00:03:42,760
Here are my wired clients, and here are my wireless clients, and

69
00:03:42,760 --> 00:03:46,100
their health right now is about 96% in terms of health.

70
00:03:46,100 --> 00:03:48,448
And when it comes down to wireless clients,

71
00:03:48,448 --> 00:03:50,859
once again about 90% in terms of health and

72
00:03:50,859 --> 00:03:54,682
all of the actual network devices that are also coming across here too.

73
00:03:54,682 --> 00:03:58,702
Now, you can hover over each one of these to essentially give you

74
00:03:58,702 --> 00:04:01,918
the information that you actually are looking at.

75
00:04:01,918 --> 00:04:06,447
And Lauren, we can even go back to the design episode that we're actually going

76
00:04:06,447 --> 00:04:10,838
to end up talking about as well, which is gonna be the idea of routers, core,

77
00:04:10,838 --> 00:04:14,103
excuse me, core distribution and access layer things.

78
00:04:14,103 --> 00:04:17,727
So we'll actually talk about the breakdown of that in network design at the point,

79
00:04:17,727 --> 00:04:21,058
but they're actually going to be listed here on how that's actually done.

80
00:04:21,058 --> 00:04:23,355
We can also view the network help that we choose to.

81
00:04:23,355 --> 00:04:28,860
Notice, we can even see the top 10 issues that my network is currently facing.

82
00:04:28,860 --> 00:04:31,711
So if I'm not sure, if I have a massive gigantic network,

83
00:04:31,711 --> 00:04:34,399
there can be hundreds of problems for all that we know.

84
00:04:34,399 --> 00:04:38,593
But not every single problem is something that would majorly stop us right now.

85
00:04:38,593 --> 00:04:40,237
What we're actually seeing here,

86
00:04:40,237 --> 00:04:43,468
through that single pane of glass that the Cisco DNA Center offers us,

87
00:04:43,468 --> 00:04:46,497
is the top 10 issues that it believes that we need to know about.

88
00:04:46,497 --> 00:04:50,948
So for instance, here, this interface connecting network devices is down.

89
00:04:50,948 --> 00:04:55,213
Also, see a layer 2 symptom, a loop symptom here.

90
00:04:55,213 --> 00:04:59,768
I can see wireless clients failed to actually connect to the AAA server,

91
00:04:59,768 --> 00:05:00,599
you name it.

92
00:05:00,599 --> 00:05:05,234
We can actually see some of that, if I select this one that is priority,

93
00:05:05,234 --> 00:05:10,027
P1 Just as an example, I now can drill down into that particular issue and

94
00:05:10,027 --> 00:05:12,920
find out are there any issues that are open?

95
00:05:12,920 --> 00:05:14,690
Yes, there's two open issues here.

96
00:05:14,690 --> 00:05:18,565
I can even discover what particular building and floor this on and

97
00:05:18,565 --> 00:05:21,770
what layer in the design that actually fits into.

98
00:05:21,770 --> 00:05:26,070
Then we can drill down into the actual specific interface as well.

99
00:05:26,070 --> 00:05:30,266
If I click on this now, I can see that it actually gives me a little bit of

100
00:05:30,266 --> 00:05:35,181
description of what's actually happened here interface, gigabit ethernet one

101
00:05:35,181 --> 00:05:40,023
slash zero slash five connecting to the following connecting the following to

102
00:05:40,023 --> 00:05:44,865
network devices is down and gives me other information that I might need to be able

103
00:05:44,865 --> 00:05:49,260
to trace out and do the other neat thing about this to Lauren is down here.

104
00:05:49,260 --> 00:05:54,207
Okay, it even begins root cause analysis for us so that we can actually go in

105
00:05:54,207 --> 00:05:59,091
to do that and use ai to help us out machine reasoning engine, you name it.

106
00:05:59,091 --> 00:06:00,909
It actually has that ability for

107
00:06:00,909 --> 00:06:04,900
us to see simple things like that about devices inside of our network.

108
00:06:04,900 --> 00:06:09,400
Now with things like that notice that we have, that's overall issues,

109
00:06:09,400 --> 00:06:14,122
I can tell if there's a network issue specifically by selecting network tab

110
00:06:14,122 --> 00:06:15,691
here and the same thing.

111
00:06:15,691 --> 00:06:19,090
Network devices, 82% of them are healthy at this point.

112
00:06:19,090 --> 00:06:23,592
It even shows me which one I might want to focus in on such as the distribution

113
00:06:23,592 --> 00:06:24,110
layer?

114
00:06:24,110 --> 00:06:29,092
I can see that this actually has another score says poor performance according to

115
00:06:29,092 --> 00:06:30,491
the little legend.

116
00:06:30,491 --> 00:06:34,210
Down at the bottom I can see this one actually has a little bit of both.

117
00:06:34,210 --> 00:06:34,980
You name it.

118
00:06:34,980 --> 00:06:37,828
You can actually go ahead and see and select right here and

119
00:06:37,828 --> 00:06:39,261
it draws you down into that.

120
00:06:39,261 --> 00:06:43,997
Specifically if I scroll down, I can continue to see even more

121
00:06:43,997 --> 00:06:49,099
information about the the access points that are actually up and

122
00:06:49,099 --> 00:06:55,230
down and even scroll down to different devices that are actually connected in.

123
00:06:55,230 --> 00:06:59,394
So you name it, if I wanted to see like one particular device,

124
00:06:59,394 --> 00:07:01,716
I'll just select this one here and

125
00:07:01,716 --> 00:07:06,950
in a moment this will actually show up inside of what they call device 3 60.

126
00:07:06,950 --> 00:07:09,918
It will actually go in and find that one single device and

127
00:07:09,918 --> 00:07:14,341
give you details about that device, the issue, the physical neighbor topology,

128
00:07:14,341 --> 00:07:18,040
the path traced, the interfaces that are actually happening here.

129
00:07:18,040 --> 00:07:19,288
The issue that's going on,

130
00:07:19,288 --> 00:07:22,470
you can see where this device is experiencing high memory utilization.

131
00:07:22,470 --> 00:07:25,933
So you have all that and then the neighbor topology,

132
00:07:25,933 --> 00:07:29,869
if you need to trace it down and figure out what's going on,

133
00:07:29,869 --> 00:07:35,570
you know what it's actually connecting to right here in this little diagram as well.

134
00:07:35,570 --> 00:07:39,561
So I can hover and view detailed information if I want you name it,

135
00:07:39,561 --> 00:07:44,498
there's a lot of different issues that are actually happening right here that we

136
00:07:44,498 --> 00:07:49,370
can take a look at clients are essentially users on our network.

137
00:07:49,370 --> 00:07:51,181
So what if I'm actually starting to go?

138
00:07:51,181 --> 00:07:53,203
All right. So what about the idea of clients or

139
00:07:53,203 --> 00:07:55,090
smaller devices here?

140
00:07:55,090 --> 00:07:57,680
We can also see that particular layer.

141
00:07:57,680 --> 00:08:02,471
So down here at the bottom notice I can actually go and find Grace smith.

142
00:08:02,471 --> 00:08:06,565
She's on a Samsung S 10 and I can click on Grace smith and

143
00:08:06,565 --> 00:08:11,020
see what issues Grace smith is actually dealing with as well.

144
00:08:11,020 --> 00:08:13,197
So we have users, we can see the network device,

145
00:08:13,197 --> 00:08:15,290
we can see the overall network if we wanted to.

146
00:08:15,290 --> 00:08:20,117
All that is truly visible when we actually get into this level of what actually

147
00:08:20,117 --> 00:08:21,250
needs to happen.

148
00:08:21,250 --> 00:08:26,202
And lastly here we're actually even able to see the applications that are running

149
00:08:26,202 --> 00:08:30,170
on our network as well and what their health status is going to be.

150
00:08:30,170 --> 00:08:34,928
So you can see right here the 83% of the business relevant applications

151
00:08:34,928 --> 00:08:36,480
are actually healthy.

152
00:08:36,480 --> 00:08:41,249
And also of course there's 18 applications which ones have poor health, I can select,

153
00:08:41,249 --> 00:08:42,011
let's say M.

154
00:08:42,011 --> 00:08:43,546
S. Office 3 65 and

155
00:08:43,546 --> 00:08:47,650
see if I can zoom back out so that we can get away here.

156
00:08:47,650 --> 00:08:50,305
And so now it's actually bringing up that information,

157
00:08:50,305 --> 00:08:53,581
we can see a timeline here of how it's actually performing over time.

158
00:08:55,160 --> 00:08:59,427
I can even scroll down once again into the issues and I can see network latency for

159
00:08:59,427 --> 00:09:03,760
for these applications that are going on as well to be able actually troubleshoot

160
00:09:03,760 --> 00:09:04,550
as we need to.

161
00:09:04,550 --> 00:09:06,471
So when we start taking a look at the D N.

162
00:09:06,471 --> 00:09:10,377
A center we're just showing you that one portion under assurance, but

163
00:09:10,377 --> 00:09:14,346
you do have all these other ones here that are actually available to you to

164
00:09:14,346 --> 00:09:18,123
actually begin your design to begin to set up policy to actually route

165
00:09:18,123 --> 00:09:21,831
traffic the way that you want to as well and even provision devices,

166
00:09:21,831 --> 00:09:25,130
which is actually probably the neatest thing that it does.

167
00:09:25,130 --> 00:09:27,650
You simply buy the devices you plug them into your network.

168
00:09:27,650 --> 00:09:30,962
The Cisco DNA center is running on your network as well and it finds it it goes

169
00:09:30,962 --> 00:09:34,223
ahead and configures it the way that you need to without having to manually

170
00:09:34,223 --> 00:09:37,670
actually even touch device after you plug it in where you think it needs to go.

171
00:09:37,670 --> 00:09:41,550
So this is why the D N A center is kind of the big push from Cisco.

172
00:09:41,550 --> 00:09:43,980
This is the future of network management,

173
00:09:43,980 --> 00:09:47,091
if not even right now that we're seeing less and less.

174
00:09:47,091 --> 00:09:49,080
Are we gonna be going to individual routers and

175
00:09:49,080 --> 00:09:50,661
switches to actually configure it.

176
00:09:50,661 --> 00:09:54,861
Now, having said that right, that's where you're gonna see in medium to large

177
00:09:54,861 --> 00:09:58,135
businesses, Most small businesses, you'll probably still

178
00:09:58,135 --> 00:10:01,620
pull out the console cable still do the configurations manually.

179
00:10:01,620 --> 00:10:03,541
So you still have to actually learn that as well.

180
00:10:03,541 --> 00:10:07,839
But hopefully laura that gives us a little bit of a taste of what we can actually do

181
00:10:07,839 --> 00:10:09,470
inside the Cisco DNA center.

182
00:10:09,470 --> 00:10:12,681
Well that is such a powerful view, it's like looking into the soul of the D.

183
00:10:12,681 --> 00:10:14,561
N. A. Center and seeing all the different options.

184
00:10:14,561 --> 00:10:17,741
So Ronnie, thank thank you so much for showing us what that looks like.

185
00:10:17,741 --> 00:10:21,150
And I hope you take a chance and look at your Cisco DNA center as well.

186
00:10:21,150 --> 00:10:22,551
But we've got more episodes to come.

187
00:10:22,551 --> 00:10:23,461
So don't go anywhere.

188
00:10:25,400 --> 00:10:27,151
Thank you for watching I.

189
00:10:27,151 --> 00:10:28,171
T pro T.

190
00:10:28,171 --> 00:10:28,671
