Common Management Interface Specification (CMIS) – OIF Common Management Interface Specification (CMIS) The management track in the PLL is currently working on CMIS 5 3, CPO ELSFP, Link training, Form Factor Specific Hardware descriptions as well as forward looking discussions of how to manage modules more efficiently Press Releases
CMIS: THE KEY TO EFFICIENT MANAGEMENT OF PLUGGABLE MODULES IN NETWORKING To address these ineficiencies and enable new management capabilities, a group of industry experts formed an independent offshoot of the QSFP-DD MSA (Multi-Source Agreement) and developed CMIS This specification was designed to generically manage the wide range of technologies within the pluggable module space Using generic management concepts, CMIS could be reused across different module
CMIS Common Management Interface Specification This Implementation Agreement (IA) defines the Common Management Interface Specification (CMIS), which may be used by pluggable or on-board modules, such as QSFP Double Density (QSFP-DD), OSFP, COBO, or QSFP, as well as by existing or future module developments with host to module management communication based on a two-wire interface
CMIS – Versatile Control Set (CMIS-VCS) - oiforum. com CMIS-VCS CMIS-Versatile Control Set: Extends CMIS base for management of advanced signal integrity capabilities on CMIS modules CMIS-LT IA In development White Paper available CMIS-Link Training: Provides details for an out-of-band link training mechanism on CMIS modules
CMIS Management Overview ECOC 2025 CMIS is a management interface for pluggable modules, defined in a family of (OIF) documents CMIS is implemented (through SW code) on the host and on the module Often overlooked, CMIS defines host to module interactions for management of the module ie provisioning, initialization, monitoring, upgrades, inventory, etc
CMIS Common Management Interface Specification Foreword This CMIS 5 1 specification was developed by the QSFP-DD, OSFP and COBO advisory group Further CMIS revisions with the same major revision number will be backwards specification-compatible to CMIS 5 1 allowing interworking in cases when host and module implement different CMIS revisions1
PowerPoint Presentation C-CMIS – Coherent CMIS – Provides extensions to CMIS to manage modules with coherent interfaces CMIS-FF – CMIS Form Factor – Provides details of HW pins and related registers for different module form factors CMIS- ELSFP – CMIS External Laser Small Form Factor Pluggable – Provides details for managing Co-Packaging and ELSFP modules
