In addition, the following component changes are applicable: Cisco vManage to Cisco Catalyst SD-WAN Manager, Cisco vAnalytics to Cisco Catalyst SD-WAN Analytics, Cisco vBond to Cisco Catalyst SD-WAN Validator, and Cisco vSmart to Cisco Catalyst SD-WAN Controller. See the latest Release Notes for a comprehensive list of all the component brand name changes. While we transition to the new names, some inconsistencies might be present in the documentation set because of a phased approach to the user interface updates of the software product. https://www.youtube.com/embed/lB_NjIzlg-U?rel=0 Course introduction Video Summary: Adrian Iliesiu, DevRel Developer Advocate, covers the details of the course including the audience for which this series is developed, the overall goal for the course, the scope of topics covered throughout this course and the basic requirements to understand the content of this series.

The Cisco DevNet Sandbox is an environment created for the DevNet community to get hands-on in a test environment. This course in particular uses a Sandbox called Catalyst SD-WAN. https://www.youtube.com/embed/HHQzH3Ve4iI?rel=0 What is Catalyst SD-WAN - part 1 Video Summary: This video covers the evolution of the WAN over the years, from the technologies of the past up to present and where we are headed in the future.

Vinay Prabhu, expert with Catalyst SD-WAN technology, discusses the basic components and functionality of a router and how the SD-WAN splits the router components into an open distributed system. He explains the concept of single touch update in the control plane implementing a network wide policy update using the Catalyst SD-WAN technology.

He discusses the concepts of overlay and underlay networks. The discussion evolves to the Catalyst SD-WAN Validator for Catalyst SD-WAN components and the formation of the “secure” channels using keys.

The concept of Secure Extensible Network (SEN) is further discussed for the Catalyst SD-WAN solution. The video covers the concept of encryption and how public and private keys work in general and how it applies to the Catalyst SD-WAN network.

A DevNet Always On Sandbox is available 24/7 at https://sandboxsdwan.cisco.com:8443 and connection detail are given in the video. The page has a self-signed certificate for a Lab environment, continue to the page through the security box pop-up. The username/password are shared in the video.

Next, Adrian presents the Catalyst SD-WAN Manager dashboard and all the components that make up the DevNet Sandbox Catalyst SD-WAN fabric and the GUI interface.

He also goes into detail on the Device Templates API that will be used extensively later in the course.

He explains how the swagger is organized and demos 3 API calls right in the swagger interface.

With the first call he gets a list of all the devices in the fabric by performing a `GET` operation on the /dataservice/device endpoint. With the second API call he gets a list of status of the devices in the fabric. In the last API call he goes over the /dataservice/statistics/interface endpoint and the data that is being returned by the API.

He goes over the github.com public repo where you can find a Postman collection and environment for Catalyst SD-WAN that you can clone and use.

After importing the collection and environment, he explains the calls available in this collection: authentication, fabric devices, devices status and device counters.

He generates Python code using the requests library for the authentication REST API call and runs the code in interactive mode.

He further explores the attributes that are available for the response object.

  • Get a list of all the devices and templates in the fabric.
  • Get a list of devices that are associated to a specific template
  • Attach and detach configuration templates to and from specific fabric devices.
After that he goes over the Python libraries that will be used to develop the application and the github.com public repo where you can download the source code.

Next he goes over the sdwan.py application and explains the purpose of each line of code. He covers importing of Python libraries used in this application, defining and importing environment variables and the Python class called that performs the Catalyst SD-WAN Manager REST API authentication.

He goes over the click library in this video and the 3 functions that are aptly named:
  • device_list()- to get a list of all the devices in the fabric
  • template_list()- to get a list of all the configuration templates available
  • attached_devices(template)- to get a list of all the devices that are attached to a specific template
