Management Interface Specification for Pluggable Modules

This white paper presents the Common Management Interface Specification (CMIS), which provides a standardized method for managing the interaction between pluggable modules and their connected devices. It outlines the evolution of CMIS, addressing the fragmentation in the pluggable module industry due to multiple management specifications that were often application-specific. The paper details how CMIS was developed to enable a unified management framework, allowing for easier integration of various module types and technologies. It explains the implementation of CMIS on both the pluggable module and host, utilizing a two-wire interface for communication. The document also describes the management functionalities supported by CMIS, including monitoring, provisioning, and upgrades. Furthermore, it discusses the role of the Optical Internetworking Forum (OIF) in advancing CMIS, ensuring its relevance and adaptability to emerging technologies. The paper concludes with the benefits of CMIS, such as reusable software, faster integration times, and the ability to address multiple protocols.
