为使本发明的实施例要解决的技术问题、 技术方案和优点更加清楚， 下面将结合附图及具体实施例进行详细描述。  The technical problems, the technical solutions, and the advantages of the embodiments of the present invention will become more apparent from the following detailed description.
本发明实施例提供一种即插即用网元设备上线方法， 如图 1包括： 步骤 101 : 通过 DHCP请求报文即插即用网元设备向网管发送， 其获 取的上线所需认证信息。  The embodiment of the present invention provides a method for the online operation of the plug-and-play network element device. As shown in FIG. 1 , the method includes: Step 101: The DHCP request packet is sent to the network management device by the plug-and-play network element device, and the acquired authentication information is obtained.
步骤 102: 网管根据接收的上线所需认证信息中包含的设备标识信息， 将接收的上线所需认证信息与其预存的上线所需认证信息进行比较， 若比 较一致则为插即用网元设备上线分配 ip地址。  Step 102: The network management compares the received authentication information of the online connection with the pre-stored authentication information required by the device according to the device identification information included in the authentication information required for the online connection. If the network management device is online, the network device is online. Assign an ip address.
步骤 103 : 通过 DHCP响应报文即插即用网元设备接收网管发送的 ip 地址。  Step 103: Receive the ip address sent by the network management device through the DHCP response packet plug and play network element device.
步骤 104: 即插即用网元设备根据接收的 ip地址上线。 具体地， 上述步骤 101 中， 获取的上线所需认证信息包括设备硬件信 息如设备的型号， 媒体访问控制 （MAC )地址， 插在机架槽位上的各主控 板和线卡信息， 以及线路连接信息， 设备硬件信息包括设备标识信息实际 应用中多采用设备序列号， 设备硬件信息还包括设备的板卡信息。 这些即 插即用网元设备上线所需认证信息是在 DHCP请求报文选项中携带的。 在 DHCP请求报文选项 Option224中携带设备的板卡信息，在 DHCP请求报文 选项 Option225中携带线路连接信息。 Step 104: The plug and play network element device goes online according to the received IP address. Specifically, in the foregoing step 101, the obtained authentication information required for the online connection includes the device hardware information, such as the model of the device, the media access control (MAC) address, the main control board and the line card information inserted in the slot of the rack, and Line connection information, device hardware information including device identification information In actual applications, the device serial number is used, and the device hardware information also includes the device board information. The authentication information required for these plug-and-play NE devices to go online is carried in the DHCP Request message option. The device information of the device is carried in the DHCP request packet option Option 224, and the line connection information is carried in the DHCP request message option Option 225.
步骤 101和步骤 103 中， 即插即用网元设备和网管， 都是通过 DHCP 服务器和对方进行信息交互， 即插即用网元设备通过 DHCP服务器向网管 发送， 其获取的上线所需认证信息， 网管通过 DHCP服务器向即插即用网 元设备发送为插即用网元设备上线所分配的 ip地址， 如 196.128.0.11。  In step 101 and step 103, the plug-and-play network element device and the network management device exchange information with each other through the DHCP server, and the plug-and-play network element device sends the authentication information to the network management system through the DHCP server. The NMS sends the IP address assigned to the plug-and-play NE device to the plug-and-play NE device through the DHCP server, such as 196.128.0.11.
步骤 103 中， 由于上线所需的配置文件被预先存储在网管中， 即插即 用网元设备获取 ip地址后 196.128.0.11，无需软件人员下现场配置初始化脚 本， 即插即用网元设备直接由网管下载配置文件完成设备上线。  In step 103, since the configuration file required for the online connection is pre-stored in the network management, the plug-and-play network element device obtains the ip address after 196.128.0.11, and the software personnel are not required to configure the initialization script on the site, and the plug-and-play network element device directly The configuration file is downloaded from the NMS and the device is online.
