Abstract: Embodiments of the present invention provide a communication method, apparatus, and system, where the communication method includes: receiving a packet, encapsulating all or a part of the packet into an Ethernet operation, administration and maintenance packet, and then, according to a corresponding relationship between a port that receives the packet and a corresponding maintenance entity group end point, sending the encapsulated packet to an apparatus that includes the maintenance entity group. The communication method, apparatus, and system provided by the embodiments of the present invention implement IP address-based communication and management for a device that does not have an IP address by means of port mapping and packet encapsulation.
