Introduction on the Key Points In the era of cloud-managed networks, Cisco Meraki has changed the way we deploy, monitor, and troubleshoot enterprise infrastructure. Gone are the days of telnetting or SSH-ing into each device individually — with the Meraki Dashboard API, you can programmatically […]
![[Day #48 PyATS Series] EIGRP Neighbor Health Check (Cisco IOS-XE / IOS-XR) using pyATS for Cisco [Python for Network Engineer]](https://networkjourney.com/wp-content/uploads/2025/08/Day-48-PyATS-Series-EIGRP-Neighbor-Health-Check-Cisco-IOS-XE-IOS-XR-using-pyATS-for-Cisco-Python-for-Network-Engineer.png)
Introduction — key points (what you’ll learn) EIGRP neighbor stability is critical for routing convergence and network stability. Small changes in SRTT, increasing retransmissions, or flapping adjacencies can lead to route withdrawal and traffic disruption. In this masterclass you will learn how to: This is […]
![[Day #26 Pyats Series] NTP synchronization check (cross-vendor) using pyATS for Cisco [Python for Network Engineer]](https://networkjourney.com/wp-content/uploads/2025/08/NTP-synchronization-check-cross-vendor-using-pyATS-for-Cisco.png)
Introduction on the Key Points In today’s fast-paced and globally distributed enterprise networks, accurate timekeeping is non-negotiable. A few milliseconds of drift between devices can lead to log mismatches, troubleshooting nightmares, and even compliance issues. This is where NTP (Network Time Protocol) synchronization plays a […]
![[Day #36 Pyats Series] Port-channel consistency validation across platforms using pyATS for Cisco [Python for Network Engineer]](https://networkjourney.com/wp-content/uploads/2025/08/Port-channel-consistency-validation-across-platforms-using-pyATS-for-Cisco.png)
Introduction on the Key Points In modern enterprise networks, port-channels (also known as EtherChannels, LAGs, or bundles) are essential for link aggregation, redundancy, and high-throughput architecture between switches, routers, and firewalls. However, one of the most common root causes of inconsistent port-channel states is configuration […]
![[Day #35 Pyats Series] Parsing and validating access-lists (ACLs) using pyATS for Cisco [Python for Network Engineer]](https://networkjourney.com/wp-content/uploads/2025/08/Parsing-and-validating-access-lists-ACLs-using-pyATS-for-Cisco.png)
Introduction on the Key Points Welcome to Day #35 of our “101 Days of pyATS (Vendor-Agnostic)” series exclusively designed for Network Engineers looking to automate their environments with ease. In today’s article, we’re focusing on Parsing and Validating Access-Control Lists (ACLs) using pyATS and Genie […]
![[Day #54 Pyats Series] NETCONF validation for Cisco/Arista/Paloalto/Fortigate using pyATS for Cisco [Python for Network Engineer]](https://networkjourney.com/wp-content/uploads/2025/08/NETCONF-validation-for-Cisco-Arista-Paloalto-Fortigate-using-pyATS-for-Cisco.png)
Introduction on the Key Points In the network automation world, NETCONF stands out as a powerful protocol to manage network devices in a structured, model-driven way. It uses YANG data models over SSH, providing fine-grained control, consistency, and programmability. In today’s post of our “101 […]
![[Day #53 Pyats Series] RESTCONF validation for Cisco IOS-XE using pyATS for Cisco [Python for Network Engineer] Introduction](https://networkjourney.com/wp-content/uploads/2025/08/RESTCONF-validation-for-Cisco-IOS-XE-using-pyATS-for-Cisco.png)
Introduction In today’s modern network automation era, ensuring API-based management protocols like RESTCONF are correctly configured and functioning is crucial for integrating controllers, orchestrators, or custom-built Python scripts for network interaction. In this Day #53 of our “101 Days of pyATS (Vendor-Agnostic)” series, we’ll walk […]
![[Day #56 PyATS Series] Automating Pre/Post Config Change Checks (Brownfield) Using pyATS for Cisco [Python for Network Engineer]](https://networkjourney.com/wp-content/uploads/2025/08/Day-56-PyATS-Series-Automating-Pre_Post-Config-Change-Checks-Brownfield-Using-pyATS-for-Cisco.png)
Introduction on the key points When working in a brownfield network, every configuration change carries risk. You must verify what is there now (pre-check), apply a change under controlled conditions, and verify what changed (post-check). Doing this manually is slow and error-prone — especially across […]
![[Day #59 PyATS Series] Detect Split-Horizon Issues in Large Networks Using pyATS for Cisco [Python for Network Engineer]](https://networkjourney.com/wp-content/uploads/2025/08/Day-59-PyATS-Series-Detect-Split-Horizon-Issues-in-Large-Networks-Using-pyATS-for-Cisco.png)
Introduction — key points Split-horizon and related route-advertisement problems are subtle but catastrophic in large networks: routes sometimes don’t propagate where they should, or — worse — are advertised back like a boomerang creating loops. Detecting these issues at scale requires automation, consistent evidence (raw […]
![[Day #55 Pyats Series] Using Cisco/Arista/Paloalto/Fortigate with pyATS using pyATS for Cisco [Python for Network Engineer]](https://networkjourney.com/wp-content/uploads/2025/08/Using-CiscoAristaPaloaltoFortigate-with-pyATS-using-pyATS-for-Cisco.png)
Introduction on the Key Points As networks become increasingly hybrid and multi-vendor, vendor-agnostic automation becomes not just a good-to-have skill, but a must-have. Whether you’re working with Cisco routers, Arista switches, Palo Alto firewalls, or Fortigate appliances—your automation framework needs to talk to all of […]
