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 3 Further CMIS revisions with the same major revision number will be backwards specification-compatible to 4 CMIS 5 1 allowing interworking in cases when host and module implement different CMIS revisions1 5 6 Revision History (Published Versions) 7 Rev 3 0August 17, 2018 8 - Initial public release
CMIS Common Management Interface Specification Abstract 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 IA - oiforum. com The CMIS-VCS Implementation Agreement defines an extensible list of Signal Integrity (SI) parameters, including their characteristics and their representation, as well as an optional versatile allocation within the CMIS Control Set
