    Join Bryan Byrne to learn Network Programmability skills that are a must have for any Network Engineer today, but it can be a challenge to get started. In this session we will break down the new IETF Standards of NETCONF, RESTCONF, and YANG and explain what each is used for, how they work together, and the key details needed to begin using them today. The session will include demonstrations that you can follow-along with live, and students will leave with sample code for exploring more later.


  • Deep Dive on JSON & more Python - listen to the replay
    Date: Wed, September 27, 2017
    Are you ready to dive deeper into using Python and REST? Join Jacob Adams to continue Coding Skills 101 topics and go deeper into techniques for parsing JSON. If you want to code along in the session, follow the instructions on this page ( ) to "Setup Your Own Computer".

  • How to be a Network Engineer in a Programmable Age - download the slides and listen to the replay
    Date: Wed, October 11, 2017
    Join Hank Preston as he discusses why "Software Defined Network”, “Infrastructure as Code”, “Cloud”, and “Programmability” all are trends that are changing the nature of being a Network Engineer now and in the future. In this session we will explore the evolution of networking and the network engineer. We'll look back fondly on the early days of networking, when the it was simple and the biggest concerns we had the number of Spanning-Tree instances to run… We 'll consider the impact of SDN, Controllers, Overlays, APIs, and more that this “Network Renaissance” has brought us. You 'll laugh, you 'll groan, you might even get angry, but that’s  okay. Come join the evolution of the Network Engineer with open eyes in DevNet and learn how to jumpstart your own transformation!

  • Build a chat bot without writing code using Spark APIs

Date: Wed, November 15, 2017       
Artificial intelligent chat bot (also known as a talkbot, chatbot, chatterbox) is a computer program which can emulate a human conversation. Rather than interacting with the bot with commands, you talk to it like you would another person. Join Steve Greenberg and see step by step how to build a useful chat bot on the spark platform without in-depth knowledge of a programming language. We'll use cloud platform as a service providers along with the Spark API to build a functional chat bot.

  • Network Programmability with Cisco ACI

Date: Thurs, November 16, 2017
Join Devarshi Shah and gain the skills required to operate Cisco ACI through this broad and extensive hands-on training experience. Uplevel your network administration skills by learning the system programmatic API's, tools available to automate tasks in the environment, including Python and REST and best practices for programmatic interaction with ACI. In this class you will be taught how to build your own scripts, and execute them, building towards a reusable simple python application to provision and manage the system.

  • Understanding Encrypted Traffic Using Joy for Monitoring Forensics

       Date: Wed, December 6, 2017

Join Bill Hudson to learn about "Joy", the open source package can track network flows and report on data features beyond those in Netflow, such as the distribution of bytes, the entropy, and the sequence of packet lengths and arrival times, as well as detailed information from TLS headers. With this data, we can better detect and understand encrypted traffic. This approach is valuable for detecting and analyzing malicious traffic, and for auditing the quality of the cryptography used to secure critical applications and communications. This session covers the Joy package, the data features that it can capture and the JSON format in which it reports data, and several use cases involving packet forensics and network monitoring.

        Date: Wed, December 13, 2017

        Time: 10:00 am PST/1:00 pm

In this session Brian Daugherty will provide an overview and demonstration of advanced VIRL features such as packet-captures, custom images, live-visualization, packet captures, and using the VIRL APIs to start and stop simulations as part of an automation tool-chain. Not familiar with VIRL? Virtual Internet Routing Lab Personal Edition (VIRL PE) is a powerful network virtualization and orchestration platform that enables the development of highly accurate models of existing or planned networks.

Hi Andy, yes - all slides and recordings will be posted here. Just updated the links above.
Community Member

Janel, ignore my direct message to you.  I just found this section....

Although I did register I didn't get a message with the webex password this time.  Have received them for others.  Different process?

Hi Todd,

That is odd! Did you receive an email invitation from WebEx?
Community Member

Thank you for the message Janel.

Originally the DevNet invitation had a link to a site that I registered for the multiple Wednesday sessions.  I marked them on my calendar since I didn’t get an invite/confirmation email for each of the registrations. (which is something most other Cisco events do provide)  The first session I got an email on the morning of the event as a reminder which included the WebEx link and the passcode.  The second session I did not get a reminder email.  I tried going to the registration site to see if there was a way to get in but could not.

☺ Lots of detail above If you’re trying to track anything down.  I don’t have the original message just it’s body that I saved on my calendar.  I appreciate the reply to my inquiry.  Hope to be able to listen live to the next one else I’ll just listen to the post-webcast thing…

How about this link Recording Information



All the new registration links (starting with trex) are broken… and even if you remove the http at the end you arrive at the „join event as panelist“ page on webex...


Hi Guys,

Each time I try to register to one of the events, the following error appears:

Your meeting service had a problem processing your request. Contact support or your administrator and provide the following error tracking ID:
