Abstract: A method for selecting a clock source includes a first network device that obtains synchronization offset data between the first network device and a second network device through a first port in a clock synchronization failed state. The first network device determines, based on the synchronization offset data, whether to refer to, during clock source selection, clock information received by the first port.

Abstract: A method includes a second system that determines a type of a first management Internet Protocol (IP) address, and sends, to a first system, first information used to indicate the type of the first management IP address; the first system determines the first management IP address based on the type of the first management IP address indicated by the first information, and releases a first correspondence between system identification information and the first management IP address to an advertisement system; the advertisement system sends the first correspondence to a network management system; and the network management system manages the first system based on the first correspondence.

Abstract: After a first network device traces a clock of a second network device, when the first network device cannot trace the clock of the second network device, the first network device modifies a parameter value corresponding to a synchronization source selection parameter of the first network device to a first parameter value, where the first parameter value is superior to a parameter value corresponding to a synchronization source selection parameter of the second network device.
