The invention relates to a method for operating a network, in which at least two network devices are connected to each other via a data line and exchange data via the data line, each network device is fixedly distributed with an independent MAC address; furthermore, the network management station controls the configuration and / or operation of the network, in which a request is sent by the network management station to the network device by means of a language-independent data format in a multicast manner in order to query configuration parameters of the network device and / or to configure the requested network device by means of the language-independent data format.

The application discloses a network expansion management method and device based on SNMPv3. The method comprises: constructing, at the proxy end, an aggregated view configuration management information base including an aggregated view configuration table and an aggregated view OID table, and a data subscription management information base including a subscription table; sending, by the network management station, a first and a second SetRequest PDU to the proxy end; creating, based on the first SetRequest PDU, an aggregated view in the aggregated view configuration table, assigning a unique name and ID to the aggregated view, and configuring, in the aggregated view OID table, a mapping relationship between each object identifier OID from different MIB trees and each aggregated view ID; creating, based on the second SetRequest PDU, a subscription entry in the subscription table, each subscription entry specifying a target aggregated view, a trigger condition and a security parameter; monitoring, by the proxy end, the target aggregated view in the subscription entry, and obtaining a target object identifier OID corresponding to the ID when the trigger condition is met; constructing, by the proxy end, an InformRequest PDU, and sending, based on the security parameter, data corresponding to the target object identifier OID to the network management station; and updating, by the network management station, the data based on the InformRequest PDU and sending back an acknowledgement. The application can improve the efficiency, real-time performance and security of network management.

The invention relates to a method for planning, operating and optionally eliminating errors in a network topology of a network having network devices, which are connected to one another in accordance with the functionality of the network, characterized in that the network devices are connected to one another in a wired manner. The topology of the network is first planned by means of a suitable planning tool, and then the planned network is in line connection with the network devices thereof, the network devices are addressed one by one from a network management station, and an IP address is assigned to each network device according to the undefined identification feature of each network device. Thereafter, the network devices receive and store their configuration data and then perform a restart on each network device to activate the received and stored configuration.
