Further, the IP addresses of all network management devices may also be recorded in the second forwarding routing table, and the network address corresponding to the valid network management device in the query record is convenient to subsequently send data to the network address of the network management device.

Step S440: Forward the downlink data packet to multiple concurrently controlled network management devices.

The downlink data packet is forwarded to multiple co-control network management devices that also monitor the network device. If there are multiple co-control network management devices that monitor the network device’s reception of the downlink data packet, the network device can also be affected by the downlink data link. The monitoring of multiple network management equipment breaks the limitation that the network equipment can only be monitored by one network management equipment in the prior art.

The monitoring method of the above network equipment is to monitor the downlink data packet in the downlink data link, and query multiple co-control network management devices that are the same to monitor the network equipment according to the second forwarding routing table, and forward the downlink to each co-control network management device Data packets are monitored by multiple network management devices of the same control to the original network equipment according to the downlink data packets, breaking the limitation that the network equipment in the prior art can only be monitored by one network management device; at the same time, a second forwarding routing table can be set The network management equipment corresponding to each network management device in the network management device can avoid adding network management equipment to change the network management device network address on each network device one by one, and it can also avoid setting the network address of each network device corresponding to the network management device one by one when adding network devices to be monitored.

Step S441: Forward the downlink data packet to multiple co-control network management devices other than the original network management device.

The above-mentioned monitoring method for network equipment can also only control multiple network management equipment other than the original network management equipment to reduce the burden on the network.

In one embodiment, after the step of querying multiple co-control network management devices that monitor the target network device, the method further includes:

Step S451: Perform device proxy service processing on the downlink data packet to obtain the relationship between the command in the downlink data packet and the target network device.

The service processing of the agent mainly refers to that the agent is responsible for the execution of management instructions and reports to the network management equipment some important events that occur in the managed object in the form of notification. The relationship obtained after the service processing of the device agent mainly reflects some important events that occur in the network device and the transmitted data packet in the downlink process.

Step S452: Upload the relationship between the command in the downlink data packet and the target network device to multiple same-control network management devices.

And step S453: sending the downlink data packet to the target network device.

The actual network address of the target network device can be obtained by querying the second forwarding routing table, and then the downlink data packet is sent to the target network device according to the actual network address.

The above-mentioned monitoring method for network equipment, according to the equipment agent processing of the downstream data, parses the downstream data packet, obtains the relationship between the command in the downstream data packet and the target network equipment, so that the network management equipment monitors the situation of the downstream data transmission and makes the routing The device implements a downstream device proxy.

In one embodiment, the network device number, network device IP address, network device port number, and protocol type are recorded in the second forwarding routing table. The network device number, network device IP address, network device port number, and protocol type are managed by the master network. The device is set according to the device information of each network management device.

Each network management device records the device information of all network devices under its corresponding management. The general network management device retrieves the device information that all network management devices need to manage, integrates and maintains it into a second forwarding routing table. The total network equipment can be a designated device in the network management equipment; the total network equipment can also be integrated and maintained by multiple designated devices in the network equipment to the second forwarding routing table, backup and store the second forwarding routing table, and improve network management monitoring Disaster resistance.

The second forwarding routing table also records the data packet monitoring relationship between the network device and each network management device.

In an example, the second forwarding routing table is shown in Table 1, where PROTOCOL represents the protocol type, and the protocol type supports both MCPC and MCPA. The "ACU1", "ACU2", "ACU3", and "ACU4" in the last four columns indicate network management equipment. If the value in the table in the following four columns is 1, it means that the data packet of this network device needs to be forwarded to the network management with value 1, which means network The data packet monitoring relationship between the device and each network management device. When the second forwarding routing table is initialized, it needs to be synthesized according to the network equipment monitored by each network management device. It is necessary to call each network management device to record a file that maintains the number of the network device, the device identification number and the ID of the network management device itself. Manage network device number (RPTNO), device identification number (DEVNO), network address (IP), port (PORT), protocol type (PROTOCOL) data and its own network management ID through the main network management device.

Uploading the relationship between the command in the downlink data packet and the target network device to the multiple co-control network management devices;

And sending the downlink data packet to the target network device.
The method for monitoring a network device according to any one of claims 4, 5 to 7, wherein the second forwarding routing table records a network device number, a network device IP address, a network device port number, and a protocol Type, the network device number, network management device IP address, port number, and protocol type are set by the main network management device according to the device information of each network management device;

The second forwarding routing table also records the data packet monitoring relationship between the network device and each network management device.
A monitoring system for network equipment, characterized in that it comprises:

The monitoring module is used to monitor the uplink data link of the monitored network device, and intercept the uplink data packet from the uplink data link;

An identification module, configured to parse the uplink data packet and identify the original network device that uploaded the uplink data packet;

The query module is used to query multiple target network management devices that monitor the original network device from the first forwarding routing table; wherein, the first forwarding routing table is used to record the relationship between the address of the network device and the address of the corresponding network management device Relationship;

The monitoring module is configured to forward the uplink data packet to each of the target network management devices, so that each of the target network management devices monitors the original network device.
