June 2026 monthly summary focused on stabilizing NH-5010 PFC watchdog handling to improve runtime reliability under PFC storms. Delivered a targeted bug fix that disables hardware PFC watchdog to route to a software ACL-based recovery path, reducing deadlock risk and improving uptime for NH-5010 SKUs.

March 2026 monthly summary for sonic-mgmt focusing on reliability and test infrastructure improvements. Delivered targeted fixes to test infrastructure that increased accuracy of PFC storm metrics and eliminated edge-case failures in PTF mappings. Two critical commits drove the month’s progress: (1) 582a8b97ac22c913fea6ec02e1c695a8d175950e — Fix incorrect total_ports calculation in test_pfcwd_all_port_storm by considering only ports with background traffic and passing selected_test_ports to verification, resolving inaccuracies and flaky tests; (2) 7c82be0a3eaeb5dc13d04269dec5c86140395486 — Fix KeyError for Q3d in PTF mapping by excluding ports with role "Ext" from the exclude list, enabling valid interface selection. These changes reduced flaky test failures and improved confidence in CI feedback for QoS and PFC-related tests.

February 2026 (2026-02) monthly summary for sonic-mgmt focusing on strengthening test reliability and expanding cross-platform support for buffer manager tests, delivering measurable business value through more stable CI, broader ASIC coverage, and higher quality validations. Key changes include introducing a wait_until-based PFC storm detection to stabilize multi-port scenarios, enabling the traditional buffer manager test on Broadcom platforms while preserving Mellanox compatibility, and hardening the test logic with improved pool/profile handling, platform-specific skip rules, and robust logging. These efforts reduce flaky test outcomes, accelerate validation of features across hardware (Broadcom and Mellanox), and improve test suite performance.
