For the first demonstration, all you need is your web browser.
In this PowerPoint presentation, I've got a link to the dev net sandbox DNA center.
So if I click on that, I'm asked to log in.
So the username that I need to use is dev net.
User password is Cisco.
One, two, three.
Bang or exclamation.
Log in.
And this is what DNA center looks like.
DNA center, like a lot of controllers, has a northbound API and a southbound API, so it can manage
network devices.
As an example, using SNMP, one of the protocols rest API.
We can see the rest API by clicking on the cog and going to API documentation.
Here's the documentation for DNA center.
So as an example, we can go to devices and we can see devices in the network by using a get statement.
So here you see some of the rest API verbs get post, put delete as an example.
I've also put a link to the documentation in this PowerPoint presentation, if you just want to click
on that and go directly to the documentation.
Here's an example of a rest uniform resource identifier or your I notice the protocol used is https
the server or host your URL is sandbox cisco ecom.
Then we've got a resource.
Here's our resource DNA intent API v one network device and then we've got parameters of that resource
in http.
This is known as a path, but for rest this identifies the resource as defined by the API.
Now that's all very good and well, but let's interact directly with the DNA Center Server API.
I'm going to use Postman to do that.
You can download Postman for free.
So as an example on a Windows computer, go to Postman.
Com.
And Click Download App.
It's picked up that I need a Windows version.
I'm going to click on the 64 bit version of Postman and click Save to save it to my local harddrive.
It's about 77 megs in size.
It's like most Windows applications very simple to install.
So I'm going to click on the installation file.
Click Install anyway.
Postman is now installing and it's starting up.
Now you can create an account to back up your data.
I'm not going to do that.
I'm going to skip signing up.
And there you go.
I've now got Postman running on a Windows laptop.
It's not a difficult application to use.
You'll need to play around with it a little bit to get used to it.
But as an example, you can create a request here.
You can click on collections to save a collection of requests that you've made.
I'm not going to use this Windows application.
I'm going to go back to my Mac.
