Ethernet control method and device used in network terminal

An Ethernet control device used in a network terminal, comprising a system terminal and a device terminal, wherein the system terminal is first application software mounted on the network terminal, and the system terminal comprises a network management module, a command transceiving module and an address request module;

• the network management module is configured for acquiring an IPv6 Link-Local address and receiving a network startup or shutdown trigger signal to manage startup and shutdown of the network;
• the command transceiving module is configured for issuing a network startup command or a network shutdown command, wherein the network startup command is an IPv6 data packet;
• and the address request module is configured for issuing an address acquisition request, and the address request module is a DHCP server;
• and
• the device terminal comprises a second Ethernet module, a protocol processing module, a network startup and shutdown control module, a state update module and an address management module;
• the second Ethernet module of the device terminal is connected with the first Ethernet module of the network terminal through a network cable;
• the protocol processing module is configured for receiving and parsing the network startup command or the network shutdown command;
• the network startup and shutdown control module is configured for enabling the address management module when receiving the network startup command and disabling the address management module when receiving the network shutdown command;
• the state update module is configured for simulating unplugging, plugging and reconnection of the network cable;
• and the address management module is configured for receiving the address acquisition request issued by the system terminal and allocating an IP address to the system terminal in a startup state.
