The Undiscovered Country : the Autocon1 recount
Intro If you are expecting my alter-ego to pop up and start the usual round of questions, he is sitting this one out. When I got back from Autocon1 my head was still buzzing for a week. I don’t know if the short stay had something to do with it (just 3 days) or maybe…
Enhancing network migrations towards an SDA Network with Nautobot, Nornir , Cisco ISE and Checkpoint Mgmt API (and your user Directory Pages) – Part 3, the process.
Last one? In the previous parts we set up the playground and looked at the planning. In this final part, we explain the process. The process After deciding what to make, and how it should function, it was time to get cooking.. (here is a nice song for you to listen while we get the…

In the previous episode.. In part 1, we have set up the playground. In part 2, we look at the planning. Migration planning – creating an appetite What’s for dinner? So what did we built exactly? And how does it need to work? Here is what we needed the code to do for each migration:…
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…
Captain’s log : A network engineer’s voyage to collecting and storing Cisco Network Devices logs to Grafana Loki.
These are the voyages.. ok enough with the Star Trek memorabilia, I was just watching Patrick Stewart on Jimmy Kimel and recently watched a couple of episodes from the TNG series, so that’s still in my mind. This post describes the way to get logs from Cisco Network Devices directly into Loki without touching a…
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. But when there is an actual need for something that these automatons can cover, that’s even better! In this case, after changing some parts of our configuration and monitoring tools arsenal…
Onboarding the network in Nautobot – a series of talks with myself and a little story telling – Part3
Is this really part 3? Well… no. Not exactly. The title would have been about Netbox but as you might have guessed, I am not using Netbox anymore. We migrated to Nautobot from Netbox 2.10.4 since summer 2021, and have been happily using it and developing on it ever since. After all this time, providing…
Old scripts (“Old Razor? – Old Face” – Sergeant Murtow, Lethal Weapon)
I was looking through my email this morning as someone needed to turn on and access a really old switch in a specific part of the network, but no one could remember the credentials. Resetting the switch would have been a big hustle in that specific area (it’s essentially a museum, the disruption would be…
How to clean up tags in your malfunctioning TIG stack for SNMP monitoring – or chasing runaway tags with InfluxQL, grep and a Python script
Hello folks, this is going to be a quick one (well compared to the others… ). A while back we had to switch our SNMP monitoring to SNMPv3, which was a bit of a problem as it wasn’t supported on all of our switches. The newer models supported both auth and priv modes but the…
