The implementation, functional features, and advantages of the present invention will be further described with reference to the accompanying drawings. The specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. Referring to FIG. 1, FIG. 1 is a schematic flowchart diagram of a first embodiment of a method for a network element to join a network according to the present invention, where the method includes: S10: The network element device sends a first protocol packet to the network element device of the upper-level node, where the first protocol packet does not carry the network management channel vlan information. The vlan in the vlan information of the NMS channel is an abbreviation of Virtual Local Area Network, which indicates a virtual local area network. The network element device is a switch or a router. In a network, the network management server is connected to at least one network element device. When the network element device is newly added to the network element device of the network, the network element device exchanges information with the upper-level node network element device connected thereto to establish a communication connection between the network element device and the network management server. When the network element device joins the network for the first time, the network element device does not have the network management channel vlan information. When the network element device sends the first protocol packet to the upper-level node network element device of the network element device, the network element device sends the first protocol packet according to the original protocol field. The network protocol channel vlan information is not carried. When the network element device of the upper-level node of the network element device receives the first protocol packet sent by the network element device, the first protocol packet is parsed. When the network device does not carry the vlan information of the network management channel, it can be determined that the network element device is a newly added network element device. Therefore, the network element device of the upper-level node of the network element device needs to send the network management channel vlan to the network element device. The information is used to enable the network element device to configure the network management channel vlan information. S20: The network element device receives the second protocol packet sent by the upper-level node network element device according to the first protocol packet, and establishes communication with the network management server according to the network management channel vlan information carried in the second protocol packet. The network channel vlan information carried by the second protocol packet is used by the upper-level node network element device for the next-level node network element device, and the vlan information of the network management channel is established. In the step S20, the network element device receives the second protocol packet sent by the network element device of the upper-level node, where the second protocol packet carries the vlan information of the network management channel (that is, the upper-level node of the network element device) The network element device writes the network management channel vlan information in the user editable field of the second protocol packet, and the network management channel vlan information carried in the second protocol packet is used by the upper-level node network element device. The level node network element device establishes the vlan information of the network management channel, and the network element channel vlan information of the upper-level node network element device for the next-level node network element device is obtained by the upper-level node network element device from the network management server, or It is said that the network management server pre-sends to the upper-level node network element device for the upper-level node network element device to provide to the next-level node network element device. The network element device parses the second protocol packet to obtain the network management channel vlan information of the upper-layer node network element device, and uses the obtained network management channel vlan information as its own network management channel vlan information, and according to the network management The channel vlan information establishes a network management channel, so that the network element device establishes a communication connection with the network management server. After the network element device establishes a communication connection with the network management server, the network element device carries the network management channel vlan information in the packets sent by the network management device. For example, when the network management channel vlan information is vlan 100, the network management channel established in the network management device is configured. All sent packets carry vlan 100. In the above embodiment, the network element device does not need to be configured with a network management channel vlan information in advance, and the network element device automatically obtains the network management channel vlan through the upper-level node network element device of the network element device. The information is used as the vlan information of the network management channel, and the network management channel is established according to the vlan information of the network management channel, so that the network element device establishes a communication connection with the network management server; the network management efficiency is greatly improved, the network management flexibility is improved, and the network is saved. The cost of opening and maintenance. Referring to FIG. 2, FIG. 2 is a schematic flowchart diagram of a second embodiment of a method for controlling a network element device to join a network according to the present invention. Based on the foregoing first embodiment of the method for controlling a network element device to join a network, after the step S20, the method further includes: S30, the network element device receiving, by the network element device, a next-level node network element of the network element device delivered by the network management server Network management channel vlan information of the device. In step S20, after the network element device establishes a communication connection with the network management server, the network management server can manage the network element device, and send the network management device of the next-level node network element device of the network element device to the network element device. Channel vlan information. In the step S30, the network element device receives the network management channel vlan information of the next-level node network element device of the network element device delivered by the network management device, and the network management channel of the next-level node network element device of the network element device The vlan information may be the same as or different from the network management channel vlan information configured by the network element device. For example, the network management channel vlan information of the network element device is vlan 100 (that is, the network element device is from the upper-level node network element device of the network element device). Obtaining the vlan information of the network management channel is vlan 100), the vlan information of the network management channel of the next-level node network element device of the network element device is vlan 200; if the network management channel vlan information of the network element device is vlan 100, the network element device The network management channel vlan information of the next-level node network element device is also vlan 100; that is, the network management channel vlan information of the next-level node network element device of the network element device can be configured by the network management server according to actual needs, and the network management server is in network planning. The configuration is implemented to avoid conflicts between the vlan information of the network management channel and the service vlan information. The network management server can set the vlan information of the network management channel of the network element devices at different levels in the network step by step, or the same. S40: The network element device receives the third protocol packet sent by the network element device of the next-level node of the network element device, where the third protocol packet does not carry the network management channel vlan information. When the network element device has the next-level node network element device, the network element device receives the third protocol packet sent by the next-level node network element device of the network element device, because the next level of the network element device The node network element device joins the network for the first time. Therefore, the next-level node network element device does not have the network management channel vlan information, and the next-level node network element is set.
