Abstract: This application discloses a port status configuration method, apparatus, and system, and a storage medium, and belongs to the communication field. In an embodiment, a configuration device obtains port datasets of M ports of N translators, where N is an integer greater than 1, M is an integer greater than 1, the N translators are integrated in at least two independent devices, the M ports are M precision time protocol ports, and the port datasets are precision time protocol port datasets. The configuration device configures port statuses of the M ports based on the port datasets of the M ports, where the port statuses are precision time protocol port statuses. This application achieves automatic configuration of the port statuses and improves configuration accuracy.

Abstract: This application discloses a clock synchronization method and apparatus, and related storage medium, and pertains to the field of communications technologies. A network device receives an announce message from a first master clock node and an announce message from a second master clock node; and when an identifier of a first clock source node carried in the announce message of the first master clock node is the same as an identifier of a second clock source node carried in the announce message of the second master clock node, selects a master clock node with a smaller clock deviation from the first master clock node and the second master clock node, and then calibrates a clock of the network device based on time information of the master clock node. The precision of clock synchronization by the network device is improved.
