In this scenario, the network management system must be connected to the management device. The PTN device on the UNI side is generally placed in a remote location. Most of them are managed by the network management server in the center. If the network management is broken, It brings a lot of trouble to the engineering staff. At present, the network management device uses the DCN (Data Communication Network) to be easily opened from the perspective of engineering applications, and most of the devices are used as non-access network elements, which requires the ports of the devices to be connected to maintain the link up. In order to ensure that the route used by the DCN is established. After the current device is restarted, all the port attributes are restored to the default values. If the current port, such as the optical port and the rate auto-negotiation mode, are inconsistent, the link will be down. When the port of the Gigabit optical hybrid board is docked, the default value of the library restart cannot be negotiated successfully. To ensure successful negotiation, you must modify the photoelectric attribute and auto-negotiation attribute configuration to ensure the link up, thus ensuring the device.
