A network management device connects to a device on the network, receives a trigger for an operation command, supplies to the device a command line interface command for the operation command, wherein a randomly generated string is included at the end of the command line interface command. The network management device receives the output of the operation command from the device, detects the end of the operation command output and parses the output using an XML-based parser. XML based configuration files are used for configuration of different network devices. XML based report files are used to generate different network reports.
