A network device and method for updating parameters of the network device provides an object adapting interface. The object adapting interface generates a service access interface and a configuration adapting interface. A management agent of the network device sends a requirement command. If the requirement command is a write command, the configuration adapting interface updates configuration parameters of the management agent stored in a configuration database of the network device. If the requirement command is a read command, the service access interface reads configuration parameters stored in the management agent.
