Developed foundational enhancements for CMIS LPO within the sonic-net/SONiC repository, focusing on improving debuggability and monitoring of CMIS modules. Delivered a high-level design document that introduced new LPO debug registers and detailed EEPROM map structures, providing the architectural groundwork for efficient fault isolation and future feature expansion. The work emphasized embedded systems and networking concepts, with a strong focus on documentation using Markdown to ensure clarity and maintainability. By establishing a robust framework for LPO debug registers, this contribution aligned with broader CMIS integration goals and set the stage for more effective debugging and monitoring in complex network environments.
