Episode Description:
If you've discovered netmiko and learned how to send and receive CLI commands from your network devices with Python, you're likely wondering "is this the best we have for network programmability?" Thankfully, the future of network automation is not a land of crafting CLI templates and parsing the unstructured clear text output with regular expressions.
In this session, we'll explore NETCONF, the widely available IETF standard for NETwork CONFiguration, and the YANG models that are providing consistent representations of concepts like "Interfaces" and "Access Control Lists." You can think of NETCONF and YANG as the next generation of SNMP and MIBs, and they were built to make network configuration through network orchestration systems and custom scripts an achievable reality for every engineer and organization.
We'll look at how to use these tools to retrieve and edit configurations, explore the operational status of a network device, and how they can be used to provide consistent control and interfacing to multiple network platforms.

Good for somebody who already knows about all this. I enjoyed it since I knew this. Good refresher. But, when I watched this 6 months back, I didn't understand a thing. Then, I watched some videos from dataknox who really went in a very fundamental and explained in a very simplified way. And now I understand what this guy is taking about

[@avadhutatre]

Have seen so many yang sessions. This one is hands down the best! Couldn't be more organised, structured and more informative. Thanks a ton guys!

[@rahulcsaple]

Excellent webinar . Contents were well structured and explained with simplicity

[@austimbo]

Awesome intro to Netconf! Enough info to get started and where to go next.

[@devnarayanpaudel1246]

Excellent webinar session about Netconf and Yang models . Well structured content and simply explained.

[@RaulEduardoFloresNajera]

Excellent info, thanks for sharing

[@DevNetDan]

Great overview of YANG and NETCONF!

[@user-xn1zl8ev3c]

very nice introduction about yang, it helps a lot for new comer

[@sandejai]

That's very informative, thank you

[@DavidTorres-mk9sk]

thanks u, good brief explanation.

[@Rileytp]

Amazing. Thanks.

[@taoli5497]

Excellent

[@mc-wi8wp]

This guy is not bad!

[@dipakkumarrai1442]

Great video. Would you kindly help me with a link or tutorial of how to go about converting a yang model into a json format?

[@vinayakkolhapure150]

Can we call a 'C' function in yang file ? Or is there any way to accomplish this ? Basically I want to call a 'C' fun which will return a integer value and use that in my .yang file.

[@cuongbang7721]

yang file is for describing data structure, so you can't call a C function in a yang file.

[@AnhHuynh-jv8to]

why we call it "Yang" ?

[@cuongbang7721]

YANG stands for Yet Another Next Gen.
