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 😉
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 🙂
As always – here are the slides from today’s webinar including all the Links needed in order to fetch the vDevices 🙂 If you encounter any problems feel free to reach out to me anytime! Thank you for joining and making these Webinars a success 🙂

Twitter just enforced new Rules:

Not at this time – My Twitter Account will be used as an archive for interested folks but will no longer post any updates or any news.
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.

Hi all, here you find (as promised) the slides from my last talk 🙂
If you have any questions or encounter problems feel free to reach out to me 🙂
For a quick “Juniper only” Lab you can also use the vLabs functionality to get started with JunOS and use your EVE-NG Server for your bigger, more customized Labs: https://jlabs.juniper.net/vlabs/
Next week, starting on Oct 17, TechFest2022 is happening 🙂 Unfortunately still virtual – hopefully we will have local TechFests in-person next year. Nevertheless, this TechFest is packed with lots and lots of great Sessions (on-demand sessions). And this one is very special for me because for the very first time I’m not “just” a partner/visitor, but also a speaker – yup – little Christian is finally wearing a bigger pair of pants 😉 Seeing my name next to my idols is somehow terrifying but also exciting at the same time 🙂 I really hope you all enjoy the talk that I had with Ola and the mighty Steve Puluka about automation. Let me know in the comments what sessions you are interested in the most 🙂
Hooray! The latest Episode of PacketPushers might be something that some of you have been waiting for: I had the honor to talk with Christopher Young and Ethan Banks about “Home IoT at scale”. It’s always fun to talk with like-minded professionals about implementations, limitations, security aspects, and basically how to push the limit of sensors more and more!
IoT will be a critical part of our everyday life – IoT is already happening if you like it or not – there’s no running away from it. This brings new challenges like IPv6-Security (and yeah – for this, you finally get to learn IPv6 – GREAT, right?), Wireless Security, Sensor Security, and Software / Patch management – something that the average User never had to deal with. But without it, he/she’s basically giving away the house key to the front door. Vendors are constantly working to bridge the gap between security and comfort for the user – curious to see what the future brings 🙂

Wow – what a way to end our 3-part-series – a live presentation from one of the EVE-NG gods himself: the mighty Uldis 🙂 If you missed this – you missed something!
As promised – here are the Slides from the last part of our series:
And of course the Video on YouTube (don’t forget to subscribe if you like the video – it helps a lot):
https://www.youtube.com/netchron/
Huge shoutouts go to Uldis – the Insights and the help have been amazing – I cannot thank you enough 🙂
And of course the best host in the universe: Christine – I really enjoyed the sessions.
Hopefully, I was able to embrace your interest in EVE-NG – especially if you want to start labbing with Juniper starting at 0€/USD (well except the server / Laptop you need lol).
Thank you all so much for attending the 2nd of our 3-Part-Series Session 🙂
As mentioned I would love if you share your Labs in our Elevate Community:
