Introduction on the Key Points Welcome back to Day 45 of our “101 Days of pyATS” series, a practical journey into vendor-agnostic automation using Cisco’s pyATS framework! Today, we’re diving deep into failover validation for first-hop redundancy protocols (FHRPs)—VRRP and HSRP—using pyATS and Genie parsers. […]
![[Day #38 PyATS Series] CPU & Memory Utilization Monitoring Using pyATS for Cisco [Python for Network Engineer]](https://networkjourney.com/wp-content/uploads/2025/08/Day-38-PyATS-Series-CPU-Memory-Utilization-Monitoring-Using-pyATS-for-Cisco-Python-for-Network-Engineer.png)
Introduction Monitoring CPU and memory utilization is crucial for ensuring optimal network device performance and avoiding outages. High CPU or memory usage can indicate problems like excessive traffic, misconfigured processes, or hardware limitations. Traditionally, engineers manually check each device using CLI commands, which is tedious […]
![[Day #44 Pyats Series] Cross-check BGP route attributes (AS path, next hop) using pyATS for Cisco [Python for Network Engineer]](https://networkjourney.com/wp-content/uploads/2025/08/Cross-check-BGP-route-attributes-AS-path-next-hop-using-pyATS-for-Cisco.png)
Introduction on the Key Points Welcome back to Day 44 of our 101 Days of pyATS Series, where we dive deep into vendor-agnostic network automation and validation techniques. Today, we’re focusing on one of the most critical aspects of inter-domain routing: Cross-checking BGP route attributes […]
Introduction Interface MTU (Maximum Transmission Unit) mismatches are a common cause of packet drops and network performance degradation. Identifying and resolving MTU mismatches across a multi-vendor environment (Cisco, Arista, Palo Alto, Fortinet) ensures consistent communication and avoids fragmentation issues. In this 101 Days of pyATS […]
![[Day #42 PyATS Series] IP SLA Monitoring Automation (Cisco-Specific) Using pyATS for Cisco [Python for Network Engineer]](https://networkjourney.com/wp-content/uploads/2025/08/Day-42-PyATS-Series-IP-SLA-Monitoring-Automation-Cisco-Specific-Using-pyATS-for-Cisco-Python-for-Network-Engineer.png)
Introduction on the Key Points In modern enterprise networks, ensuring end-to-end service availability and performance is critical. Cisco’s IP SLA (Service Level Agreement) feature allows network engineers to measure parameters such as latency, jitter, packet loss, and response times between devices. Traditionally, IP SLA statistics […]
Introduction on the Key Points Neighbor discovery protocols like CDP (Cisco Discovery Protocol) and LLDP (Link Layer Discovery Protocol) play a crucial role in identifying directly connected devices in a network. As a Python for Network Engineer practitioner, automating neighbor validation ensures accurate documentation, topology […]
![[Day #47 PyATS Series] Logging & Debug Outputs Parsing Automation Using pyATS for Cisco](https://networkjourney.com/wp-content/uploads/2025/08/Day-47-PyATS-Series-Logging-Debug-Outputs-Parsing-Automation-Using-pyATS-for-Cisco.png)
Introduction on the Key Points When managing Cisco networks, logging and debugging outputs provide the most critical visibility into network events. However, parsing through thousands of syslog messages or debugging outputs manually is time-consuming and error-prone. This is where pyATS comes in — Cisco’s Python-based […]
