Abstract: Embodiments of the present invention provide a link switching method, device, and system. The method comprises: an optical network unit (ONU) transmits a monitoring packet through a first Maintenance association End Point on a first link connected to the ONU and an aggregation side switch device, so as to monitor the first link; the ONU performs switching from a first sub-link of the first link to a first sub-link of a second link if it is detected that a link fault occurs on the first link; the ONU sends a notification message to a second optical line terminal (OLT), so that the second OLT enables a transmission port; and the ONU sends an automatic protection switching message to the aggregation side switch device through a second Maintenance association End Point on the second link.

Abstract: The present invention discloses a service configuration method, apparatus and system. The provided method includes steps as follows: configuring a VLAN ID of a port on an intermediate device according to preset configuration information, where the port is connected to a client; after a DHCP request message which is from the client through the intermediate device is received, obtaining a MAC address in the DHCP request message, and obtaining an IP address corresponding to the MAC address from the configuration information; and sending a response message carrying the IP address and the VLAN ID to the client through the intermediate device, so that the client sets a local virtual local area network identifier to the VLAN ID and sets a local IP address to the IP address after receiving the response message.

Abstract translation: 本发明公开了一种服务配置方法，装置和系统。 所提供的方法包括以下步骤：根据预设配置信息配置中间设备端口的VLAN ID，其中端口连接到客户端; 在接收到来自客户端的DHCP请求消息之后，获取DHCP请求消息中的MAC地址，并从配置信息获取与MAC地址对应的IP地址; 并通过中间设备向客户端发送携带IP地址和VLAN ID的应答消息，使得客户端将本地虚拟局域网标识符设置为VLAN ID，并在接收到IP地址后将本地IP地址设置为IP地址 响应消息。
