Abstract
A troubleshooting method, a device, and a readable storage medium are provided, to detect a unidirectional fault in a ring Ethernet and provide a fault recovery mechanism after the unidirectional fault occurs. In embodiments of this application, if determining that a link corresponding to a receiving unit of a first port is in a fault status, the first device performs loopback on the first port, and sends a first continuity check message to a second device via the first port. The first continuity check message carries first indication information. The first indication information indicates that a link corresponding to a receiving unit of a port that sends the first indication information is in a fault status.
