YANG Explained and Explored | Pyang | DevNet | CCNP

[@gorebrush]

I feel old. CCIE since 2015, been in IT since 2004... - and this makes me feel like i'm green all over. I love it.

[@mrhinton101]

This is great. Its nice to see the network world embracing programmability. I may be one of the first subscribers to your CBT Nuggets series. Its been nearly 10 years since I last attempted a new Cisco cert but this may be the one.

[@DataKnox]

Awesome! Let's get it!!

[@ravindravyasit123]

Excellent.........no words out standing.......you write abstract of research paper(yang)..so read only abstract

[@oasis5827]

Great Video! Thank you for posting. I'm a CCNP just learning SDN and YANG etc. I have a long way to go in understanding the entire DEVNET training and certification. IT has taken some time just to get down all of the new acronyms included in all of this. I really am interested in getting the DEVNET Cert and also becoming proficient in using the technology. Thank you!

[@adamlicht6614]

Knox, you are the man. Nice work and very well presented. Thank you!

[@DataKnox]

Not gonna lie - I was sweating releasing this video. It’s HARD to summarize something as big as YANG in about 10 minutes!

[@mikewhitney7345]

Thanks for helping clearing up the confusion I had with YANG in relation to network devices and interfaces

[@DataKnox]

You bet!

[@kewlguyjason]

great explanation and easy to understand. Following the devNet guide and configuring loopback / configure hostname was easy. Trying to dig out another IETF YANG data model and trying to configure BGP, OSPF, DHCP was hard/almost impossible. My guess is you explain how to do it in your course

[@dv7045]

Hi. Can you tell me please, can I implement MIBS module (yang) to explore data from pppoe connection on ASR router with tree view structure ? Thanks for help.

[@BlindPigBluesBand]

Awesome video and great explanation! What? You can use context manager for the connect method? Brilliant. It’s easy to forget to close the connection when you’re beginning to program.

[@ahmedareem9599]

Great explanation Sir!

[@asa9593]

Thanks Xnox, it was clear at the beginning. However, as you got to python commands

[@DillyDogSays]

Where do I learn about different yang like open, native, ietf. for testing questions?

[@DustinJohnson1]

FYI you could have just passed in the dictionary as kwargs. It would be as clean as with manager.connect(**router): LOVE the Yang topic though. thank you for a great video

[@williamcleek4922]

Splatting in params is prob a bit outside the scope of the video

[@muhammad.rafi2012]

Another great video but it would also be beneficial if you go through little bit of YANG common statements e.g. leaf, leaf-list etc.

[@marteenhd]

Wow! Great video!

[@DataKnox]

Thanks!

[@arturogonzalezbocanegra7073]

what does the " * " in some leafs inside the tree mean?

[@rakesh4a1]

Question: ncclient::connect() does this use SSH or TLS as transport protocol? Nice and clear.

[@DataKnox]

It uses Netconf which leverages SSH to transport

[@shahrinsharif9642]

This is really helpful.. thanks

[@Qweklain]

When I try to run Pyang, it just opens the 'pyang' file in the Python\Scripts\ folder no matter what I do. In other words, running "pyang " just keeps opening that pyang file. I have searched all over and there is no explanation or solution. Why is it doing this?

[@techevangelist8373]

Great video. Question- With yang working together with restconf or netconf, we can now configure any vendor device or get the operational data from any vendor device without having to know, what is the actual command we should be using on a particular vendor device. Is that correct? Also, can I compare YANG like SNMP MIBS and netconf or restconf like snmp protocol?

[@DataKnox]

You’re correct on both accounts. But know that there are vendor-specific models (called Native models) that provide more data than the industry standard models

[@techevangelist8373]

@@DataKnox thanks. One last thing, I am in this industry for more than 7 years now and all these time, I never had to learn SNMP MIBS and still I was able to work and troubleshoot issues. So, if YANG is like MIBS, is it like something good to have while working these days but, not a must knowledge. And we will still need all the other networking concepts. Right?

[@CakRama01]

How to know get_schema value? For example on your video ietf-ip. How about another? And how to find that for example bgp state information

[@RaulEduardoFloresNajera]

Get the capability of device using ncclient

[@harsha00761]

Beautiful !!!

[@mikearrera8672]

Great video! Do you have any information about connecting to the DevNet Sandbox to use automation tools? I would like to be able to play with IOS-XE without having a physical device. I am assuming this can be achieved with VIRL as well?

[@DataKnox]

I used both in my CBT Nuggets course, and we even have a skill on prepping a study environment

@@DataKnoxI will have to check those out! I am about 1/3 of the way through right now

[@alexeyleontiev7388]

It amazing and very interesting.

[@asa9593]

Do I need to have an understanding of Python before I persue DEVNET Associate with CBTnuggets?

Thanks Knox 😊. Your work ethic is inspirational, hope you stay disciplined.

Did you ever passed on CCIE exams?

Cool and all but I don't understand why this is needed? Seems useless.
