David Penaloza decided to demystify Cisco’s SD-WAN, provide real world experience beyond marketing hype, and clear confusing and foggy messages around what can or cannot be done with Cisco SD-WAN.
He started the first part of his Cisco SD-WAN Foundations and Design Aspects webinar with a quick look beneath the surface of shiny marketing and corporate slidess.
In today's Heavy Networking episode, we talk Production Ready Automation. That's a topic we've covered before on Packet Pushers, so what wondrous newness does sponsor Cumulus Networks bring to the table? The idea is a system that's ready for you to use. Why? Because a lot of folks are finding that rolling their own artisanal network automation takes considerable time both to create and maintain. Our guests are Pete Lumbis, Director of Technical Marketing and Rama Darbha, Director of Services at Cumulus Networks.

Recently, COBOL has been in the news as the State of New Jersey has asked for help with a COBOL-based system for unemployment claims. The system has come under heavy load because of the societal effects of the SARS-CoV-2 virus. This appears to have prompted IBM to offer free online COBOL training.
As old as COBOL is (60 years old this month), it is still heavily used in information management systems and pretty much anywhere there’s an IBM mainframe around. Three years ago Thomson Reuters reported that COBOL is used in 43% of banking systems, is behind 80% of in-person financial transactions and 95% of times an ATM card is used. They also reported 100s of billions of lines of running COBOL.
COBOL is often a source of amusement for programmers because it is seen as old, verbose, clunky, and difficult to maintain. And it’s often the case that people making the jokes have never actually written any COBOL. We plan to give them a chance: COBOL can now be used to write code for Cloudflare’s serverless platform Workers.
Here’s a simple “Hello, World!” program written in COBOL and accessible at https://hello-world.cobol.workers.dev/. It doesn’t do much--it Continue reading
Other vendors such as Juniper and AWS have already started doing it, now it’s Cisco’s turn to offer online testing. This is especially welcome in Covid times where it’s difficult to go visit an on-premises Pearson/Vue test center. Starting April 15, Cisco will offer remote testing and this means you can take your test any time, any day, around the year. Almost all of the written tests will be offered, including the DevNet ones! The CCDE is one of the excluded tests.
What is required to take the test online? There are some prerequisites:
Your test will be proctored by an online proctor. Before the test starts, you will need to show your room, that there are no books or notes, that you are alone in the room and that you can close the room etc. As well that you are not wearing a watch or have access to a mobile phone. You will also need to provide a valid ID before starting the test. If you break any rules, you will of course not receive a passing score. You can find more information in Susie Wee’s Continue reading
One of the attendees of my Building Network Automation Solutions online course quickly realized a limitation of Ansible (by far the most popular network automation tool): it stores all the information in random text files. Here’s what he wrote:
I’ve been playing around with Ansible a lot, and I figure that keeping random YAML files lying around to store information about routers and switches is not very uh, scalable. What’s everyone’s favorite way to store all the things?
He’s definitely right (and we spent a whole session in the network automation course discussing that).
In this week's episode Ed, Scott, and Tom discuss one of IT networking's biggest challenges, IP renumbering, and how IPv6 impacts (and is impacted by) it. Anyone who's ever had to do a significant IPv4 renumbering project knows just how labor intensive and painful this process can be. Will it be easier with IPv6? If so, how and why?
