Abstract
A second device sends a first message to a first device to request the first device to establish a unicast connection to the second device. The first message carries a medium access control (MAC) address, an address identifier, and a security mechanism of the second device. The first device determines, based on the first message, that establishment of the unicast connection between the first device and the second device is abnormal, and sends a second message to the second device. The second message carries the MAC address, the address identifier, and an error identifier of the second device, so that the second device performs corresponding handling based on a reason why establishment of the unicast connection is abnormal that is indicated by the error identifier.
