Abstract

A configuration management device for vendor-independent network device configuration includes a network interface unit for communicating with network devices over a communications network and a data storage unit. The network interface unit can include a unified device network interface and a device-specific driver unit, where the unified device network interface can: retrieve a device profile; to identify a network device which belongs to a network device type corresponding to the device profile; retrieve information on a device-specific configuration protocol to be used during configuration of the network device; and download values for the vendor-independent configuration parameters to the network device.
