CMIS (Common Management Interface Specification) has emerged as the leading management interface for the modules ranging from copper cables to coherent pluggable modules.\nSONiC provides support for custom-built CMIS compliant modules with extended capabilities like updating the firmware on the remote end of the cables like AEC and ACC and support of custom memory map.\nLearn how SONiC is extending the capabilities of CMIS compliant modules and providing following advantages:\n1. Custom feature support with custom memory map\n2. Platform/ASIC/Switch and module vendor agnostic support\n2. Dynamic port breakout support for modules supporting multiple applications\n3. Streaming telemetry for DOM (Digital Optical Monitoring)\n4. Custom host side and module side signal integrity support\nAlso- we can learn from Nvidia’s story of moving from their custom firmware handling of the modules to SONiC adoption for managing the modules with improved link reliability along with hitless upgrade of the NOS.
