Problems solved by technology
[0006] When there is a third-party network, since the Option field is user-defined, no public organization guarantees the uniqueness of its value. Therefore, in the case of a third-party network, it may be different from the value of other network elements. conflict
In addition, the above solution requires the network element to store a self-identifying SN number, or requires engineers to input a KEY value on site, which increases the manufacturing cost and installation cost of the network element

Embodiment 1
[0040] Embodiment one, see figure 1 Detailed description, figure 1 It is a schematic flow chart of the method in this embodiment.
[0041] Send a DHCP client request message to the DHCP server, and the DHCP client request message carries the network management interface hardware address of the network element to be installed;
[0042] After the network element to be installed is started, any available service interface can be selected to send a DHCP client request message to obtain configuration information. This message is a broadcast message. After the DHCP relay agent receives the broadcast message, it will The broadcast message is converted into a unicast message and sent to the DHCP server (DHCP server).
[0043] The packet encapsulation format for obtaining configuration information by sending a DHCP client request is as follows: figure 2 shown.
[0044] Among them, the destination address DMAC of the link layer protocol fills in the broadcast MAC, the source addres...

The embodiment of the invention relates to installation method of network element, including the steps: sending DHCP client request message to DHCP server, wherein the DHCP client request message carries hardware address of network management interface of the network element to installed; receiving DHCP server response message returned by the DHCP server, wherein the DHCP server authenticates thenetwork element to be installed according to the hardware address of network management interface of the network element to be installed and then returns the DHCP server response message; and installing the network element to be installed according to configuration information carried by the DHCP server response message. The invention can simply, conveniently and flexibly realize access network element installation in one step and can support access network element installation while penetrating third party network scene.
Description
technical field [0001] The invention relates to the field of communication, in particular to a network element installation method, a network element, a DHCP server and a network system. Background technique [0002] The installation of network elements is a very expensive part of the network construction process. In addition to the wiring of network elements completed by hardware personnel, it also includes the initial configuration of network elements completed by software personnel. Among them, the initial configuration of network elements is relatively complicated. At present, operators have requested that the installation of network elements can be completed in one visit. One stop means that one engineer can complete the installation of network elements once on site. Therefore, how to realize the automatic configuration and installation of network elements becomes the key to one-stop installation. [0003] At present, most of the automatic configuration solutions adop...
