Should I Take CCIE DC or ipSpace.net Data Center Online Course?
Got this question from a networking engineer who couldn’t decide whether to go for CCIE Data Center certification or attend my Building Next-Generation Data Center online course:
I am considering pursuing CCIE DC. I found your Next-Generation DC course very interesting. Now I am bit confused trying to decide whether to start with CCIE DC first and then do your course.
You might be in a similar position, so here’s what I told him.

Cleared JNCIS-Devops
Last week I went to write JNCIS-Devops exam, I was under an impression that I may not be able to clear it but good did happen!
First and Foremost
-> I had the official training for JAUTcourse – The course is extremetly helpful as it provides the precise material and also the structured lab environment for you to explore and study, nothing beats a class-room study and training environment
But, after appearing I can tell you that you dont really require the offiicial training (if that is the only thing stopping you to think about the exam), the exam will test you for your understanding of automation philosophy and also how Juniper Implements it.

ipSpace.net Subscription Now Available with PayPal
Every second blue moon someone asks me whether they could buy ipSpace.net subscription with PayPal. So far, the answer has been no.
Recently we started testing whether we could use Digital River to solve a few interesting challenges we had in the past, and as they offer PayPal as a payment option, it seemed to be a perfect fit for a low-volume trial.
The only product that you can buy with PayPal during the trial is the standard subscription – just select PayPal as the payment method during the checkout process.
Finally: the first three subscribers using PayPal will get extra 6 months of subscription.

Worth Reading: The Death of Expertise
Bruno Wollman pointed me to an excellent article on the ignorance of expertise and confidence of the dumb. Here’s the TL&DR summary (but you should really read the whole thing):
- The expert isn’t always right;
- An expert is far more likely to be right than you are;
- Experts come in many flavors – usually you need a combination of education and expertise;
- In any discussion, you have a positive obligation to learn at least enough to make the conversation possible. University of Google doesn’t count;
- While you’re entitled to have an opinion, having a strong opinion isn’t the same as knowing something.

PQ 145: Greg And Ivan Have A Chat
In the ten or so years I ve been blogging, Ivan Pepelnjak has been constant figure in the tech industry. His prolific blogging and sharing of knowledge is one of the inspirations for my own entry into blogging. Over the years, we have usually agreed violently on most things and disagreed on others.
His ipSpace website has grown from a blog into a membership and more recently into a consulting service.
On today’s Priority Queue, Ivan and I talk about automation, intent, product quality and what can be done to improve it, the direction private clouds might take, and whatever else catches our fancy.

Last–but not least–in the technology triumvirate presenting a joint session at Networking Field Day 17 was Cumulus Networks. This post looks at the benefits of Cumulus Linux as a NOS on the Mellanox Spectrum Ethernet switch platform.
Cumulus Networks
I’ve not yet managed to deploy Cumulus Linux in anger, but it’s on a fairly short list of Network Operating Systems (NOS) which I would like to evaluate in earnest, because every time I hear about it, I conclude that it’s a great solution. In fact, I’m having difficulty typing this post because I have to stop frequently to wipe the drool from my face.
Cumulus Linux supports around 70 switches from 8 manufacturers at this time, and perhaps obviously, that includes the Mellanox Spectrum switches that were presented during this session. This is the beauty of disaggregation of course; it’s possible to make a hardware selection, then select the software to run on it. Mellanox made a fairly strong case for why the Spectrum-based hardware is better than others, so now Cumulus has to argue for why they would be the best NOS to run on the Mellanox hardware.
Cumulus Linux, as the name suggests, is based on Debian linux. Continue reading

Plotting the interface flap – That’s some analysis
Hi,
What started to be a exploration project is now turning out to be pretty useful for me in day to day analysis. Back in days when I worked in support, there was nothing to predict or really worry about historical events for any future work, just grep for logs and you are done with the last flap and analysis.
Customers / Networks now look for more data, while there are systems which do the telemetry and prediction, from an analysis point of view, as an engineer I want to know if the device or a circuit over an interface is stable over a period of time or even if it flaps what is the likely time and day it flaps in a week for a smoother migration.
Requirement : Plot a simple graph analyzing the interface flaps over a period of one week for a specific interface and decide the actions next from the log messages.[in this case i used a junos device]
Well grepping the logs is not something new for a seasoned engineer but having visual data will prove to be useful for a cutover or migration.
There are systems which can do this work on Continue reading
