Concise monthly summary for 2025-09 focused on delivering tangible improvements in network discovery and data integrity for the Cisco IOS collection. Key achievements loaded into the collection: - LLDP neighbor chassis_id parsing and inclusion: Implemented parsing support for chassis_id in LLDP neighbor information and included it in the ansible_net_neighbors dictionary. This enhances auto-discovery fidelity and network topology mapping. - Parser integration and class coupling: Added parse_chassis_id in the device output parsing flow, integrated with the Interfaces class to ensure chassis_id data propagates through common models. - Test coverage: Added unit tests to verify correct extraction of chassis_id and its inclusion in net_neighbours data. - Change reference: Commit 3f8eacd90bcb0c0b8fc944d6030313c67c88e6ff (Add chassis_id LLDP fact to net_neighbours fact. (#1229)). Major bugs fixed: - No major bugs reported this month related to LLDP chassis_id parsing; updated parsing path reduces potential for missing chassis_id in net_neighbours and improves stability when collecting neighbor data. Overall impact and accomplishments: - Improved data fidelity for network topology in Ansible automation, enabling more reliable inventory, monitoring, and automation workflows that depend on LLDP chassis identifiers. - Reduced manual data cleaning by enriching net_neighbours with chassis_id, aiding change detection and troubleshooting across devices. Technologies/skills demonstrated: - Python parsing logic enhancements, data modeling in dictionaries, and integration across the parsing and models layer. - Test-driven development with unit tests ensuring correct extraction and propagation of new data fields. - Version control discipline with a focused commit addressing a concrete data enrichment feature.
