April 2026 monthly summary for sonic-buildimage. Delivered a high-priority bug fix that stabilizes Arista port behavior by changing the default auto-negotiation configuration in hwsku port_config files. The default is now off for Arista platforms, with explicit exceptions for devices that require autoneg (Moby 7060X6-16PE-384C and Arista-720DT-48S with RJ45 BASE-T ports). The change reinforces predictable network behavior, reduces misconfig risk in deployments, and aligns with vendor expectations. All CI builds and KVM tests passed for this change.

March 2026 monthly summary: Hardware SKU configuration enhancements for PFCWD support and broader hardware recognition in sonic-utilities. Implemented TH5 HWSKU in the pfcwd support list and expanded recognition to non -B- hardware SKUs, improving deployment reliability and cross-device compatibility. This work increases hardware ecosystem coverage and reduces manual validation across devices. Commit activity demonstrates strong traceability and code hygiene.

December 2025: Delivered two key enhancements in sonic-buildimage that strengthen cross-role QoS consistency and hardware compatibility. QoS Configuration Synchronization Across LT2 and T1 implemented via a symlink-based propagation, ensuring updates to LT2 QoS settings are reflected in T1, reducing configuration drift and improving maintainability. Hardware Compatibility: 400g/300m Cable Length Support added to pg_profile_lookup for Arista-7060X6-64PE-B-P32O64, enabling new F2 topology deployments and broader hardware support. No major bugs fixed this month; minor stability improvements maintained. Overall impact: improved maintainability, faster deployment readiness, and broader hardware support; enhanced reliability of QoS configuration across roles. Technologies demonstrated: symlink-based config propagation, cross-role configuration consistency, and per-model hardware capability extension, with clear commit history.

Monthly summary for 2025-10 focusing on features delivered, bug fixes, impact, and skills demonstrated in sonic-net/sonic-mgmt. Key work: expanded SNMP link-local test coverage across DT2 topologies LT2/FT2 to improve reliability and reduce regression risk.

Sep 2025 monthly summary for sonic-buildimage (sonic-net/sonic-buildimage). Delivered two primary items focused on reliability and traffic management for Arista platforms, aligning with product goals and customer value.

July 2025 monthly summary focused on expanding Sonic Build Image hardware coverage by delivering Arista-7060X6-64PE-B-P28O72 SKU support. Implemented end-to-end recognition and configuration for the new port layout (28x800G and 72x400G) and added new configuration templates for buffers, buffers, port configuration, QoS, SAI profile, and BCM to enable proper onboarding and operation of the SKU. The work was committed as a single change (commit 71994ea61b2b904c76fa62986426595917c614c2) under issue #23358. This feature enhances market coverage and reduces onboarding time for new Arista hardware in sonic-buildimage.
