PQ 146: Practical Python For Deploying BFD
Today on the Priority Queue, some practical Python for network engineers.
My guest is Billy Downing, and we walk through an example of how to use Python to deploy BFD, or Bidirectional Forwarding Detection.
We start by describing BFD and how it works, and then explore how to use Python to make it go in your network.
Billy is a data center engineer who works for the Department of Defense. Check out his blog at NetworkTechStudy.com.

FreeZTP: Zero-Touch Provisioning for Cisco Catalyst
Configuring Cisco IOS switches the “old-fashioned” way can be a time consuming and tedious task. Pull out the serial cable and USB adapter, connect your laptop to the switch, and sit on the cold raised floor banging away at the keyboard until you have remote access and can escape to a more terran-friendly environment.

Datanauts 130: The Good, Bad And Ugly Of The VAR Life
If you work for a Value Added Reseller (VAR) as an engineer, the value being added is YOU.
What is VAR life? Projects, customer meetings, deadlines, bills of materials, RFP responses, and trying to turn the promises of sales unicorns into an actual design you can install for the customer.
We’ve worked for VARs at one time or another, as has our guest Eric Gullickson, who is now Enterprise Architect at Vortex Optics. We thought we d run down the good, the bad, and the ugly of the VAR life on this episode of the Datanauts podcast.
We start the show by distinguishing the different roles a VAR can have. Then we dive into the good, which includes access to new technology, paid certifications, a flexible work schedule, and exposure to a wide variety of businesses and operating environments.
For the bad, the Datanauts and Eric discuss the blunt reality that you have to generate profit, and you may find yourself having to navigate the competing interests of manufacturers, sales, distributors, and customers.
On the ugly side, we swap stories about greasy salespeople, bad project management, and other nightmares.

Take a Network Break! Cisco puts its Tetration workload protection product into the cloud by announcing a SaaS version, and attackers target Cisco’s Smart Install feature on the IOS and IOS XE operating systems.
Juniper aims to entice service providers by integrating telemetry, AppFormix, and its NorthStar WAN SDN controller for improved remediation, HPE acquires a cloud consultancy, and Riverbed CEO and cofounder Jerry Kennelly retires.
Cradlepoint partners with Webroot for secure SD-WAN, an activist investor target MicroFocus to go private, and cryptomining attacks increasingly target the enterprise.
Last but not least, Gartner predicts explosive cloud growth, and IDC says lines of business will outspend IT departments on technology.

Facebook is the current villain of surveillance capitalism, but other tech giants may find themselves being asked difficult questions about what they know about us.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.

If you d heard of Cisco Tetration when it was first announced, you might have a vague memory of it being this huge rack of hardware at an eye-watering price that did some sort of analytics for massive data centers.
Tetration has evolved into a platform that meets needs for organizations of many sizes. Tetration also has a bunch of genuinely interesting use cases, as Cisco has become increasingly clever about what they can do with all of that data Tetration gathers.
For example, you can auto-implement a whitelist policy for application workloads. You can detect when your apps are deviating from their normal traffic patterns. You can detect software vulnerabilities. And depending on where you run Tetration, you can still get deep network performance insights, what I think of as the original Tetration value proposition.
Today on this sponsored episode, we delve into what Tetration does, explore use cases, and dive into how it fits into compute environments. Our guests from Cisco are Jason Gmitter, Principal Systems Engineer; and Yogesh Kaushik, Senior Director of Product Management for Tetration.

Today the Datanauts explore three key concepts to make cloud management and operations more bearable: automation, understanding new services and capabilities, and security.
Our guest is Kenneth Hui, Technical Marketing Engineer at Rubrik. Ken blogs at Cloud Architect Musings. While our conversation focuses primarily on AWS, many of the principles discussed will apply to any cloud platform.
In part one we parse automation, infrastructure-as-code, and DevOps to understand how these concepts are related, how they differ, and why culture and human behavior matter more than labels.
Part two explores the latest offerings in AWS including serverless, container support, and machine learning.
Part three tackles cloud security essentials including encryption, not exposing S3 buckets, and best practices.
