I achieved a part of my all-time-goal and got all written Juniper Certifications :)

      1 Comment on I achieved a part of my all-time-goal and got all written Juniper Certifications :)

I’m REALLY REALLY excited to share some news with all of you – those of you who will be in Madrid this July for the TechSummit 2023: Prepare to party 😀


With the EoL of both the JNCIP-Cloud and the JNCIE-Cloud, I can officially announce that after working tirelessly for the past 12 years I now hold each JNCIA, each JNCIS, and each JNCIP that is currently available 🙂


And you know what? I didn’t even realize this was happening until I tried to register for my last missing P (JNCIP-CLOUD) for the TechSummit this year and “failed” to register due to the EoL-Announcement which I completely missed…

But don’t worry – I still have a LOT to study for (and panic in the exam room) and I will hopefully still meet some of you at the certification booth in Madrid this year. Just because I can’t sit in a written exam anymore doesn’t mean I can’t wish everyone going for an exam all the best in-person 🙂 And trust me: If I can do it – YOU CAN DO THIS 🙂

With both Cloud P and E gone, “all that’s left” (Yeah – I said it out loud…) for me is the
JNCIE in ENT, DC, and SP – so prepare Exams, because I’M COMING FOR YOU!

It will be a lot of hard work, will require my full attention (after all it’s the Masterclass of Exams), and will cost me even more grey hairs + also a lot of sleep. However, if you ask me it’s totally worth it (anyone who ever took an E-Exam will know what I mean). The path towards an E-Level-Exam is filled with so much knowledge and so many new things to learn, how can anyone not enjoy this? 🙂

HUGE HUGE shoutouts go out to 2 very important people in my career that always helped me and whom I could always ask for advice during my Juniper certification journey: Staci and Adam
I literally cannot thank you both enough for always supporting me and always guiding me and the community 🙂 You folks are special and you are the reason that I stand here today and I will never forget that!
Additionally, I want to thank the Team at Axians Networks & Solutions for creating an environment that allows me and all of my wonderful colleagues to shine and work on so many awesome projects!

Since I cannot register for an Exam anymore, I have a Voucher to give away 🙂
It’s valid for any written Exam (A, S, or P-Level) and is valid until 2024. I don’t like the idea of first come first serve so this giveaway will be a bit different: DM me on Mastodon, or Twitter (yes, I opened my DM’s there), or write me a Mail and tell me, what exam you want to try and why. You don’t need to send me an essay but maybe more than just “give voucherz pleaz” 😀
The giveaway is open until July 11th and I will reach out to the winner on July 12th – maybe I can even deliver this voucher in Madrid if you are there 🙂

The vEX (EX9214 virtual) is finally out!

      7 Comments on The vEX (EX9214 virtual) is finally out!

As some of you have noticed, we got a little something: https://support.juniper.net/support/downloads/?p=vjunos
That’s right – it’s the new vEX that I already mentioned due to some rumors floating around in my last Webinar is finally out 🙂

It’s available for download now if you have a Juniper Account. Sadly, the image seems to have some issues and unfortunately, no one was reachable yet to discuss these issues from the Juniper side. If you are a Juniper dev for the vEX and like what we do with the EVE-NG Team then please reach out to me directly!
The Version is already fully supported in EVE-NG but there are still a lot of questionmarks left when it comes to the implementation and the configuration.

Hopefully, next time early access is granted to the folks doing extensive testing for virtual solutions (WINK WINK) to be able to solve the first questions BEFORE the image is released – this would have solved some confusion for sure 😉

Anyways – Let’s hope the vEX delivers what was promised (fully integrated into MIST including Campus-Fabric) so that we can finally have a virtual MIST Lab 🙂 I keep you posted once I’ve tested this image extensively myself.

Update 2023-04-25:
Juniper’s vEX (vjunos-switch) dev reached out to me so we can work on the remaining questions 🙂 THANK YOU SO MUCH!

mARVIS “Vaccine” – now with EX4400 Cloud Infusion :D

When Covid really hit everyone I asked my Wife to create this for me 🙂
I designed the Sticker and she filled this with Water (I mean pure concentrated AI magic fluid) – thought you folks might like this 😉

Ending the vQFX shenanigans – changing the serial number

      1 Comment on Ending the vQFX shenanigans – changing the serial number

Have you ever encountered this really nasty “bug” where your vQFX will turn into the Linecard (LC) Role? Yeah – welcome to the club!

Thankfully you can avoid this (most of the time if the vQFX shows some mercy) by changing the Serial Number. My guess is, that the vQFX sees the remote PFE with the very same S/N and tries to bind to it – which will fail and therefore put the RE into the LC-state.

First power up your vQFX – you will immediately be presented with the current S/N during the very first messages when the RE boots:

Login as root and edit the file called /boot/loader.conf (trust me, it’s there) 😉

Scroll down to the very bottom and you will see the S/N:

Now you need to know a bit of vi-magic: use the shortcut “dd” to delete the line where your cursor is at (or manually go to the edit mode and delete the last line). Save the file (:wq!) – if you don’t force(!) it, the device will tell you this is a “read-only” permission. After that, reboot the RE.

Notice now, that this time during boot, there is no S/N – so the Junos bootup routine will generate a new one for you:

After the device boots, you can either issue “show chassis hardware” or re-enter the same /boot/loader.conf file to see our new and shiny S/N – with this, the vQFX will not try the usual shenanigans again – well, hopefully…

Hope this helps you on your Lab-Quest 🙂

My new DayOne GREEN Book is out :)

      1 Comment on My new DayOne GREEN Book is out :)

If you love your garden-power-plant you shouldn’t look at my new DayOneGreen Book 😀
I had some free time and used it to write a teaser for my new book, which will hopefully be published in 2023 🙂

It is extremely important to me to pass on knowledge – that has always been my attitude.

In three examples I will show you how you can save a lot of money by virtualizing your lab environment and at the same time reduce your CO2 footprint – even more with the Juniper vLabs – even in small environments.

Incidentally, at #Axians we are constantly developing new ideas together with #JuniperNetworks to make networks even more efficient and “simpler”. At the end of the day, solutions must also be manageable for small teams – that’s a challenge we accept 😉

Feel free to contact me if you have any questions.
