Introduction Border Gateway Protocol (BGP) is the backbone of modern enterprise and service provider networks, enabling scalable routing between different autonomous systems. Validating BGP neighbor relationships across a multi-vendor environment is critical for ensuring routing stability and avoiding outages. Traditionally, engineers log into each device […]
![[Day #23 PyATS Series] Interface Error Counters Monitoring Using pyATS for Cisco](https://networkjourney.com/wp-content/uploads/2025/07/Interface-error-counters-monitoring.png)
Introduction Monitoring interface error counters is crucial in maintaining a healthy network. Errors such as input drops, CRC errors, and collisions can significantly degrade performance and lead to network outages. Traditionally, network engineers manually run show interfaces commands on each device to track these errors—a […]
![[Day #22 PyATS Series] Interface Status Check Across Vendors Using pyATS for Cisco](https://networkjourney.com/wp-content/uploads/2025/07/Day22-PyATS-Series-Interface-Status-Check-Across-Vendors-Using-pyATS-for-Cisco.png)
Introduction In every production network, ensuring interface health and status consistency across devices is crucial. A single downed port can lead to outages, suboptimal routing, or even compliance issues. Traditionally, engineers log into each device to verify interface states, which is error-prone and time-consuming. With […]
![Day #16 PyATS Series] Automating Common CLI Commands (Multi-Vendor) using pyATS for Cisco – Python for Network Engineer](https://networkjourney.com/wp-content/uploads/2025/07/Day16-PyATS-Series-Automating-Common-CLI-Commands-Multi-Vendor-using-pyATS-for-Cisco-–-Python-for-Network-Engineer.png)
Introduction Welcome to Day #16 of the 101 Days of pyATS (Vendor-Agnostic) series. In this lesson, we focus on automating common CLI commands across multi-vendor environments (Cisco IOS-XE, Arista EOS, Palo Alto PAN-OS, Fortinet FortiOS) using pyATS. As networks grow more complex, engineers often need […]
![[Day #15 PyATS Series] Building a Reusable Test Template for All Vendors using pyATS for Cisco – Python for Network Engineer](https://networkjourney.com/wp-content/uploads/2025/07/Day15-PyATS-Series-Building-a-Reusable-Test-Template-for-All-Vendors-using-pyATS-for-Cisco-Python-for-Network-Engineer.png)
Introduction Welcome to Day 15 of the 101 Days of pyATS (Vendor-Agnostic) journey. As a network engineer stepping into the world of automation, one of the first challenges you’ll face is code duplication. When you manage networks with multiple vendors—Cisco, Arista, Palo Alto, Fortinet—it’s common […]
