An Ethernet ring protection switching (ERPS) method and a node, where the method includes clearing, by a first node, media access control (MAC) address forwarding tables of a first ERPS port and a second ERPS port, and simultaneously changing multiple ports including the first ERPS port and the second ERPS port to a broadcasting state when the first ERPS port becomes faulty, where the second ERPS port is another ERPS port except the first ERPS port, sending, in a broadcasting manner using a port in the multiple ports, the MAC packet to a target node when a MAC packet is received, and changing the multiple ports to a forwarding state, learning a MAC address according to a broadcasting path of the MAC packet to obtain a target MAC address forwarding table of the second ERPS port. Hence, ERPS efficiency may be improved.
