Week 6 of the DevNet Grind – Model Driven Programmability, YANG Data Modeling, NETCONF and RESTCONF Protocols reviewed for exam day!

The above is graphic is how YANG / NETCONF / RESTCONF flow like an OSI Model! "Yet Another Next Generation" or YANG is defined in RFC 6020 as a "Data Modeling Language" used to model Configuration and State data manipulated by "Network Configuration Protocol" (NETCONF), NETCONF RPCs, and NETCONF notifications. 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!

Hank Preston Video Series – Module 3 – Model Driven Programmability with YANG Data Models, NETCONF, and RESTCONF reviewed!

A quick review of some different items in Hank Preston's free video series First and foremost, hats off to Hank Preston on this great video series, and any notes here in are my own understanding (I try not to type verbatim for the sake of understanding the concept), so all credit to him for the … Continue reading Hank Preston Video Series – Module 3 – Model Driven Programmability with YANG Data Models, NETCONF, and RESTCONF reviewed!

ENAUTO – RESTful APIs and RESTCONF completely reviewed, some much needed comparison to NETCONF, and configs!

RESTCONF is the cousin of NETCONF which both use YANG Data Modeling to talk, although while I know NETCONF prefers XML as its choice of encoding data to communicate and SSHv2 via TCP Port 830 to communicate, I assume that is where we will see some differences between RESTCONF and NETCONF protocols. With that lets … Continue reading ENAUTO – RESTful APIs and RESTCONF completely reviewed, some much needed comparison to NETCONF, and configs!

ENAUTO – Fundamentals and Introduction to all things Automation!

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!
