March 2026: Implemented the Flow Session Management CLI for the SONiC DPU within sonic-net/sonic-utilities, enabling operators to trigger and dump flow sessions to improve observability, troubleshooting, and overall flow management in DPU deployments. The work is captured in a single change (commit 44f8c37b12d96bda84570ad6f8dd12f23c24c73d) with associated test coverage enhancements and static check fixes. There were no major customer-facing bugs fixed this month; however, internal quality improvements reduced static analysis issues and expanded test coverage. Impact: faster diagnosis of flow-related issues, better operational visibility, and a more robust DPU flow management workflow. Technologies/skills demonstrated: CLI/tooling design, DPU flow management, static analysis, test-driven quality improvements, and cross-team collaboration.
