The DB-API subsystem provides a special datastore editing interface for subsystems to access the YANG-based data controlled by the main server. It can be used by network management components within the device that operate in addition to the netconfd-pro server.
The DB-API service provides the ability for a subsystem to send a configuration edit to the main server. The YControl protocol is used to manage the connection and communication with the main server.
For more information see the DB-API Subsystem section in the YumaPro Server Overview.
