python

This week I will dive more into a network programmability topic. I will show you a practical use case for the Cisco NX-API. It provides an interface to communicate with a Nexus device using HTTP/HTTPs using JSON or XML. Because of the reliable request-response nature of the HTTP protocol, it is usually more preferable than scraping Telnet/SSH outputs.

This week, I will show you how to build a simple python based configuration generator using the Jinja2 library with CSV and JSON based parameters.

With this post, I’ll like to share with you my thoughts, why programming may be relevant for network engineers and why I named it as the first learning area for network programmability and automation in my “how to start” post.

Some weeks ago, I got the request to check parts from more than 5000 lines show inventory output for there end of live state. How to handle this at scale? My solution: parse the data using TextFSM.
