Though YANG generally describes Network … Continue reading Week 6 of the DevNet Grind – Model Driven Programmability, YANG Data Modeling, NETCONF and RESTCONF Protocols reviewed for exam day!
This is a logical look at how the NETCONF Protocol is made up, I will get into defining some portions of this below, but wanted to give a visual look at how NETCONFIG is structured as a Protocol. Now for a quick overview, unfortunately this does draw a bunch of comparison again to SNMP, however … Continue reading ENAUTO – NETCONF Intro, Lots of SNMP Comparisons to NETCONF operation, lots of good info for exam day and beyond!
Created a new lab in EVE with a working Ubuntu 16.04 Desktop VM within it, bridged to the LAN at my house along with 4 x 7200 series routers to do some automation stuff, so we are inching closer to getting out of the fundamentals and back into labbing! 🙂 I took a screen grab … Continue reading ENAUTO – How to find YANG Models for different vendors on GITHUB, and how to view them using Linux Terminal!
The above illustration is a very straight forward "Module" for YANG, and the components of coding elements that make up YANG Modules, this is an actual tiny piece of real code formatting for YANG to reference when looking at Terminology / Concepts below. Now this first part will tie back to my previous post on … Continue reading ENAUTO – Comparison of SNMP to NETCONF, YANG Terminology / Concepts, and where to find YANG Data Models!
I will start with the very fundamentals of what / why Network Automation is around today, and then go further into some concepts regarding it. Network Automation - What goals does it achieve? Reducing node by node updates with bulk updates to the network Eliminate repetitive tasks entirely Standardize the network and documentation (consistent images … Continue reading ENAUTO – Fundamentals and Introduction to all things Automation!
