The setup This post is written as the echo of the Autocon3 conference in Prague fades away and right after the GRNOG18 conference (GRNOG – Greek Network Operators Group) in Athens. This time we ‘ll deal with some hard questions.. We are going to ask and discuss about a lot of “Why”s. Mainly the “why”…

Enhancing network migrations towards an SDA Network with Nautobot, Nornir , Cisco ISE and Checkpoint Mgmt API (and your user Directory Pages) – Part 1, the playground.
Intro Catch up In a previous post, I described how we used Nautobot to serve as a dynamic inventory for Nornir, using a Nornir plugin made for this purpose, to build our client location history for the legacy access network. As I mentioned there, we were preparing to migrate our metro area Access Network to…
Developing a custom solution for mac address collection and storage using Nornir, Nautobot and InfluxDB v.2.x
The use case As a tinkerer, I really like putting things together, especially if they go on working on their own like little automatons.
