A device management system that receives a first service request message for a remote device node, the request including an address identifier and a connection profile identifier. The system retrieves from a database protocol configuration information associated with the service request. The system connects to the remote device using the protocol configuration information and iterates through device packs and identifies a device type and support for in-band and out-of band application protocols for the remote device. The system retrieves and stores the retrieved device type and in-band and out-of band application protocols. The system further receives a second service request message that includes a device identifier of the remote device and iteratively connect to the remote device associated with the device identifier using each of the in-band and out-of band application protocols and retrieves an inventory of management operations associated with each application protocol.
