1
00:00:05,310 --> 00:00:08,370
For the first demonstration, all you need is your web browser.

2
00:00:09,090 --> 00:00:15,330
In this PowerPoint presentation, I've got a link to the dev net sandbox DNA center.

3
00:00:15,810 --> 00:00:18,630
So if I click on that, I'm asked to log in.

4
00:00:19,200 --> 00:00:22,630
So the username that I need to use is dev net.

5
00:00:22,650 --> 00:00:25,140
User password is Cisco.

6
00:00:25,680 --> 00:00:27,120
One, two, three.

7
00:00:28,340 --> 00:00:29,960
Bang or exclamation.

8
00:00:30,760 --> 00:00:31,440
Log in.

9
00:00:34,430 --> 00:00:37,430
And this is what DNA center looks like.

10
00:00:39,050 --> 00:00:44,810
DNA center, like a lot of controllers, has a northbound API and a southbound API, so it can manage

11
00:00:44,810 --> 00:00:45,710
network devices.

12
00:00:45,710 --> 00:00:49,880
As an example, using SNMP, one of the protocols rest API.

13
00:00:51,850 --> 00:00:56,710
We can see the rest API by clicking on the cog and going to API documentation.

14
00:01:00,130 --> 00:01:02,740
Here's the documentation for DNA center.

15
00:01:03,040 --> 00:01:11,710
So as an example, we can go to devices and we can see devices in the network by using a get statement.

16
00:01:11,770 --> 00:01:20,380
So here you see some of the rest API verbs get post, put delete as an example.

17
00:01:21,620 --> 00:01:26,810
I've also put a link to the documentation in this PowerPoint presentation, if you just want to click

18
00:01:26,810 --> 00:01:29,390
on that and go directly to the documentation.

19
00:01:29,900 --> 00:01:38,980
Here's an example of a rest uniform resource identifier or your I notice the protocol used is https

20
00:01:38,990 --> 00:01:43,880
the server or host your URL is sandbox cisco ecom.

21
00:01:43,880 --> 00:01:45,890
Then we've got a resource.

22
00:01:45,920 --> 00:01:55,400
Here's our resource DNA intent API v one network device and then we've got parameters of that resource

23
00:01:56,000 --> 00:01:56,870
in http.

24
00:01:56,900 --> 00:02:03,500
This is known as a path, but for rest this identifies the resource as defined by the API.

25
00:02:04,250 --> 00:02:09,770
Now that's all very good and well, but let's interact directly with the DNA Center Server API.

26
00:02:10,190 --> 00:02:12,630
I'm going to use Postman to do that.

27
00:02:12,650 --> 00:02:14,480
You can download Postman for free.

28
00:02:15,110 --> 00:02:18,220
So as an example on a Windows computer, go to Postman.

29
00:02:18,640 --> 00:02:19,130
Com.

30
00:02:20,230 --> 00:02:22,180
And Click Download App.

31
00:02:22,510 --> 00:02:25,600
It's picked up that I need a Windows version.

32
00:02:26,080 --> 00:02:33,310
I'm going to click on the 64 bit version of Postman and click Save to save it to my local harddrive.

33
00:02:33,610 --> 00:02:35,980
It's about 77 megs in size.

34
00:02:36,670 --> 00:02:39,880
It's like most Windows applications very simple to install.

35
00:02:40,330 --> 00:02:43,540
So I'm going to click on the installation file.

36
00:02:45,350 --> 00:02:46,940
Click Install anyway.

37
00:02:52,570 --> 00:02:55,780
Postman is now installing and it's starting up.

38
00:02:56,170 --> 00:02:59,560
Now you can create an account to back up your data.

39
00:02:59,860 --> 00:03:00,970
I'm not going to do that.

40
00:03:00,970 --> 00:03:02,620
I'm going to skip signing up.

41
00:03:03,040 --> 00:03:04,060
And there you go.

42
00:03:04,090 --> 00:03:08,050
I've now got Postman running on a Windows laptop.

43
00:03:08,470 --> 00:03:10,920
It's not a difficult application to use.

44
00:03:10,930 --> 00:03:13,890
You'll need to play around with it a little bit to get used to it.

45
00:03:13,930 --> 00:03:17,110
But as an example, you can create a request here.

46
00:03:17,680 --> 00:03:23,950
You can click on collections to save a collection of requests that you've made.

47
00:03:25,000 --> 00:03:26,980
I'm not going to use this Windows application.

48
00:03:26,980 --> 00:03:28,870
I'm going to go back to my Mac.
