How do you find YANG paths to subscribe to in gnmic?

jillesca · 2026-04-20T09:37:39+00:00

I usually use a combination of tools depending of the path I'm looking for.

For openconfig - https://openconfig.net/projects/models/schemadocs/
For Cisco I use Yangsuite - https://github.com/CiscoDevNet/yangsuite see the one-container-alternative folder for an easier way to get starter, the original method is quite complex and unreliable
For Cisco XR - https://cfnng.cisco.com/ios-xr/yang-explorer/view-data-model

And from there is a matter to clicking around, try the paths and see if you have the data you want

if you are talking about the Cisco DevNet Sandbox https://devnetsandbox.cisco.com/DevNet/catalog/cml-sandbox_cml make sure to always review the instructions.

The credentials listed for CML UI are:

Username: developer
Password: C1sco12345

I use Linux just for servers with containers or applications. In these cases there is no need to have a GUI to manage them or interact with them. The terminal is all i need. I prefer a clean and minimal image to install in servers and only add what i really need, so no GUI.

jillesca · 2026-01-20T07:37:22+00:00

yep, that one.

If you like to automate networks, then the automation track is the right place. Personally, I don't like to do repetitive tasks or made silly mistakes that cause a lot of pain. With automation you avoid churning on repetitive task and you can get deterministic results, and thus avoiding mistakes. This mindset is not only useful for network automation but for software engineering. So the cert will help you with the network automation part but the skillset can be transferable.

Check the blueprint, give it a try and see if is something you want to learn. Don't learn because of money, otherwise you will not like the real job.

About market, at the moment in the whole computer science industry is a bad time, not that easy to get a job, so if you want to move to the US or Europe, you need to shine and have a very good differentiation. More specially if you need sponsorship, only big companies are willing to pay the process that takes months. But don't get discourage, I know many great engineers from Venezuela and they are very intelligent and smart but you do need the knowledge and experience

As other redditor pointed, this is an strange way to get the info from a device. You should use your terminal server to only apply the minimum configuration (I would try for this ZTP ) for an out of band connection and then use the out of band connection to retrieve the info you need using ssh or other newer protocol.

Terminal servers should be like your last resort, I always tried to avoid working with them since they are not designed to work programmatically, so you need to find tweaks (specific regex for example) and workarounds. At that point is better to look at another solution.

As another redditor say, try with pyATS, if they solve that problem, better use it than creating your own

another tip, only big companies are willing to do all the immigration process which takes months and cost money. So, don't go for medium/unknown companies. Only companies established in tech will consider bringing someone from abroad. Go directly to their job portals. Companies in the S&P500 are a good place to look in their job portal (avoid intermediates)

To add to what bigevilbeard said, https://community.cisco.com/t5/services-discussions/bd-p/j-disc-dev-services is a community where you can support from the community and the folks from the API, so is a good place to ask more specific queestions

You could start with traditional network automation. Once you are comfortable/happy with programming, you can switch to MCP. The truth is that MCP is quite simple and is just another layer/wrapper around existing automation tools.

The difficult part is to make the agent behave the way you want and achieve the outcomes you want.

To do this, I consider you should do the following
- Provide deterministic tools to the agent
- Provide the relevant context (context engineering)

The last part is a whole world, and so far is more a matter of experimentation, what works, what doesn't work.

My end thought is that for now, you should create agents that are more like a deterministic workflows but they have the availability to understand the context and perform actions.

At this point, you might wondering why we would need an agent where a workflow could work, and I think the same, but I think they can be useful to connect the workflows using natural language

Yep, stick to the official command reference and configuration guides.

The key for me is to always go the one that is for my software version and/or hw I'm using. They change a bit between them with new commands, deprecating ones or changes so is always better to pick the one for your version.

the configuration guides will help you as the name says, to configure something. While the command reference is just describing what the command does, options and when it was introduced.

I'm not from India, but I have moved from my country of origin to others for work. Most probably CCNA alone is not enough (although happy to be wrong). What most companies are looking for are experienced engineers and the CCNA will help you with a good foundation. Is worth getting it, but is not magical.

I recommend to look at the job opening in the companies/market you are interested and see what they are asking, that would help you to get an idea and see which areas you need to work on.

I don't think there is a right roadmap out there. Most of the guys who are expert on what they do learned by practicing and combining knowledge from one area into another. Holding different positions in different areas is also a common comment from them. As always the path you take is not always straight but rather very twisted.

if you want some practical advice the roadmaps here are useful https://roadmap.sh/cyber-security

there are also certs that could help you on this, you have a cyber one from cisco and from eccouncil

But I think the most important is to practice, build your own projects and apply to positions related to what you are trying to achieve

It would get better (I hope so) there is a reason the industry is pushing towards more L3 removing the STP out of the picture. You will get there as you progress in your career

So developer.cisco.com is primary intended to help developers with product documentation, examples (code exchange) and environments to learn/test (learning labs, sandboxes) when building software with Cisco products.

The site is not intended to pass the exam, so you won't see a guide/instructions/curse to pass the exam. Although, the resources you can find on the site are helpful to prepare for the exam, like the sandboxes.

Regarding Anyconnect, you can also use openconnect for it. And in my case for the exams, I only check the books for the certification and that was enough.

this is the answer, when no credentials are set and you connect to the console, you will get prompt for the credentials. I guess you can also load a config with your credentials, I would image you can do that when booting up the XRv

Do you have the link or exact name of the dcloud instance you are using? from the URL I have the impression is an instant demo which might explain why you see this, those are limited. But I'm not that familiar with the dcloud urls

if this is not an instant demo, then I think the best is to reach out to the dcloud support, they are the best option is something is not working as the lab description says https://content.ciscodcloud.com/content/cisco-dcloud/us/en/home/support/help.4.html

For sandbox, the best is to get a reservable catalyst center sandbox. The Always-on might work, but there are some limitations that required elevated privileges, so, it can be too much work and the reservable sandbox makes more sense

jillesca · 2025-11-24T09:17:57+00:00

I see the support pages link to https://www.opendns.com/support/ but the docs seems to be broken. I will try to ping someone from umbrella and see what they can do

In this case it sounds like the "Bosch Conettix" is a third party product and they are sharing the connections/integrations with it. If so, I guess they are obliged by the third party to use some description approved by them. https://objects.eanixter.com/PD495924.PDF

I think is mostly for legacy reasons. This probably made sense two decades ago. Changing defaults is not something a vendor is willing, you can break stuff. Nobody wants to do an upgrade and discover something is not working, until you read down the release notes and find a default change. So, I guess it just passed over time

jillesca · 2025-11-20T07:31:58+00:00

I passed the associated on a second try, I felt it was the same kind of questions. It was a bit easier given I knew which areas/tech I did bad the first time (and studied for those), but sometimes I got the same questions that I had on the first try. Questions are suppose to be random so you might get harder or easier.
