The Direct Console User Interface provides access to basic operations for vCenter Server management and set up.
The DCUI provides access to a subset of management functions. It provides direct access to vCenter Server if the vSphere Client and the vCenter Server Management Interface become unavailable.
For an illustration showing vCenter Server connections, see the block diagram vCenter Server Management Connections.
After the vCenter Server startup is complete, the DCUI displays basic CPU, memory, and network information on the operator console. The root user can use the DCUI screen to configure network interfaces, DNS, and super administrator password.
