During a two-month period, Arunkumar Pannerselvam enhanced the sonic-net/sonic-mgmt repository by expanding Marvell-teralynx support in SONiC leaf-fanout and improving upgrade reliability for T1 topologies. He updated Python-based test suites to cover new ASIC types and implemented conditional logic to skip unsupported upgrade paths, broadening hardware validation and reducing deployment risk. In addition, Arunkumar authored a comprehensive ARS Validation Test Plan in Markdown and YAML, standardizing the verification of Adaptive Routing and Switching features. His work demonstrated depth in test planning, configuration management, and cross-team collaboration, resulting in reusable validation frameworks and improved platform coverage without introducing regressions.
In March 2026, delivered a comprehensive ARS Validation Test Plan for SONiC in the sonic-mgmt repo, focusing on Adaptive Routing and Switching (ARS) validation with emphasis on load balancing and traffic distribution across configurations. This work aligns with the ARS High-Level Design (HLD) and references sonic-net/SONiC#1958, with changes captured in commit d8d7366f672abb67e98e79d7a6d9f1120840b47f (ARS test plan #21237). No major bugs fixed this month. Impact: provides a standardized, reusable validation blueprint that reduces risk in ARS deployments and accelerates verification cycles. Demonstrates strong skills in test planning, documentation, cross-functional collaboration, and traceability to issues and commits.

February 2026: Delivered expanded Marvell-teralynx support in SONiC leaf-fanout and improved upgrade reliability for T1 topology. Updated tests for new ASIC types/platforms (including tag packet support in access ports) and implemented a conditional skip of the upgrade path to avoid unsupported scenarios. These changes broaden hardware coverage, reduce upgrade risk, and strengthen validation. Demonstrated expertise in test automation, platform validation, and cross-team collaboration.
