Common Management Interface Specification (CMIS) defines, starting with revision 4.0, a standard mechanism for managing the firmware of compliant transceivers. This mechanism allows for transceivers’ firmware to be updated without having to remove the transceiver from the switch. Firmware updates may be necessary in a testing or production environment to resolve potential firmware bugs. Some transceivers may also support firmware management operations in a hitless manner (without impacting traffic).

The feature allows a simulated transceiver removal, without physically touching the module. This can be used for

Optics 4.21.5F 4.22.0F Transceiver

This feature introduces support for the SFP-10G-MRA-T SFP transceiver. This is a rate adapting transceiver, meaning it can convert the system side interface to a lower rate on the line side.

This feature adds support for viewing the Digital Optical Monitoring (DOM) parameters for the optics that support
