摘要： A fault information processing method implemented by a first interface with a physical layer (PHY) chip and a media access control layer (MAC) chip, includes, after receiving first fault information sent by a second interface communicating with the first interface, sending by the PHY chip second fault information to the MAC chip, where the first fault information indicates that the second interface detects a fault, and the second fault information indicates that the fault is from the second interface. Because the PHY chip has received the first fault information, a link between the PHY chip and the second interface is normal. Because the MAC chip can normally receive the second fault information, it indicates that communication between the PHY chip and the MAC chip is normal. The fault information processing method is used to determine the fault from the second interface.
