The future of CLI and how Network Engineers will interact with devices is a topic being discussed quite often. ERRATA: link in tweet is broken, go HERE for the correct page "I'll give you my CLI when you pry it from my cold, dead fingers" - said no #CCIE ever, they're busy automating their networks with Python to save …

Quite often cable management is something that starts well when a new IDF is deployed and then gets messier over time. Cable p0rn channel on reddit shows plenty of example of how cabling should look like. I usually don't do cabling and I'm not good at it either so I'll not post my home lab setup ;-) Unpatchable? The …

I read a lot of discussions about complexity in networking and IT today that include a large amount of FUD. Topics range from "we'll all lose our jobs because abstraction" to "you can't fix complexity" to "welcome robot overlords" ;-) Info Complexity is something that may be easy to move, even easier and to increment, …

White boxes and their impact on enterprise networking is a hot topic today, with many point of views. The last update from Dave Temkin, VP of Network Architecture ad Netflix, put more gasoline on the flames: **Update April 2018: the original tweet was deleted, the message was: Super proud of my team - today they …

In episode 13 of the Network Collective podcast around minute 26 Jordan Martin asks: Aren't we all just following a trend? The discussion topic is how to mentor juniors in a learning path to grow their skills and be experts eventually. The question can be translated as: Are we creating fake (IT) news/trends or is it …

This week I've attended the Network Automation Seminar organized by Reiss Romoli. The speaker was the great Ivan Pepelnjiak! I was happy to meet Ivan again after NFD16. At the event I joined old and new friends: Andrea, Nicola, Paolo and Tiziano. Are these networkers or programmers? ;) @ioshints @adainese @nmodena …

Day two of NFD16 started with Apstra and their intent-based networking system. Intent concept is not as broad as SDN but still vendors have different views of this meaning. According to Apstra an intent is "the definition of the expected outcome". The sum of the intents of a network is the source of truth. Read Sasha …

Welcome back to AirPiConsole blog post, this is part two. If you read part one and followed the configuration steps you should now have a fully working Raspberry Pi Zero W connected to your WiFi network. You should also be able to connect via Bluetooth to get a console connection without knowing the IP address of the …

As a network engineer I spend a lot of time with my laptop connected via serial cable to various devices. Physical serial connection is needed for initial device setup and sometimes per customer's security policy I can't access the network, so I can only use out-of-band management. I also configure many devices at …

For me this usually means core switch replacement. Today I was moving a configuration from an HP8200 to a Cisco 4500, taking care of all the …

Ansible has been around for I while but I didn't had a chance to play with it so far. Now the time has come: I manage enough IOS devices with homogeneous configurations in multiple sites without Cisco Prime. Any change is a pain, it's time to automate all the things! My environment I run Ansible inside Bash on Windows, …
