This is an ecosystem of CLI commands that allow the user to create and apply override profiles for the various CDB capabilities and related EOS software controls of CMIS-compliant transceivers. A profile consists of a set of parameters which, when configured, replace the default parameters provided by the transceiver or by EOS.

Historically EOS transceiver-related configurations have been applied on a per-interface or per-slot basis, however this approach is inefficient in applying a configuration that is relevant to a group of transceiver modules determined by certain criteria.

To address such use cases, the concept of “transceiver matching rules” is being introduced.

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 400GBASE ZRP (also known as ZR+) is a transceiver that follows the OpenZR+ MSA (Multi Source Agreement)

Common Management Interface Specification (CMIS) compliant transceivers are configured by selecting an
