Rajshekhar worked on enhancing MACsec backend selection and reliability across the sonic-net/sonic-swss and sonic-net/sonic-mgmt repositories. He developed a deterministic mechanism for selecting the MACsec backend on gearbox ports by introducing a per-PHY capability flag in the gearbox configuration, using C++ and Python for orchestration logic and unit testing. His work ensured that MACsec orchestration defaults to the PHY switch when supported, with a safe fallback to the NPU or global switch, improving platform compatibility. Additionally, he stabilized MACsec configuration and teardown processes, implementing robust retry logic and synchronization to reduce test flakiness and improve system resilience.
February 2026 monthly summary highlighting delivery on MACsec reliability, configuration stabilization, and robust teardown/restart resilience across sonic-mgmt and sonic-swss. Focused on stabilizing MACsec test and production behavior, reducing flakiness, and improving overall system reliability and security posture.

January 2026 monthly summary for sonic-swss: Delivered a deterministic MACsec backend selection mechanism for gearbox ports by introducing a per-PHY capability flag in the gearbox configuration. Default MACsec orchestration now uses the PHY switch when available, with a safe fallback to the NPU/global switch when a PHY is marked as not supporting MACsec, addressing failures in MACsec creation on gearbox ports lacking a MACsec engine.
