OPTICAL NETWORK TERMINAL MANAGEMENT CONTROL INTERFACE MESSAGE TRANSMISSION METHOD AND SYSTEM, AND CORRESPONDING DEVICE

摘要

The present application discloses a method, a system and a related device for transmitting an OMCI message. The method includes: sending, by an optical line terminal device, configuration information to an optical network terminal device, where the configuration information is used to instruct the optical network terminal device to configure a multicast port on the local node to an enabled status so as to establish a multicast channel; and sending an OMCI message that carries multicast information to the optical network terminal device through the multicast channel, where the multicast information includes a multicast port identifier and the multicast port identifier is used to reflect a mapping between the OMCI message and the multicast port.
