In the communications field, an MEP configuration method and an Ethernet device are provided. The method includes: receiving, by an Ethernet device, a CCM message and parsing the CCM message to acquire configuration information in the CCM message and a virtual local area network VLAN of the CCM message; and determining, by the Ethernet device according to configuration information, whether the CCM message is MEP configuration that needs to be configured, and if it is determined that the CCM message is the MEP configuration that needs to be configured, complete the MEP configuration according to the configuration information and the VLAN of the CCM message. A method provided in a specific implementation manner of the present invention has an advantage of configuring MEP configuration automatically.
