摘要： A method for monitoring time synchronization, an apparatus, and a system are provided. The method includes: A first network device obtains synchronization path information (S401), where the synchronization path information is information about a synchronization path between a first time synchronization device and a time source. The first network device obtains time offset information of a plurality of time synchronization devices (S402), where the time offset information of each of the plurality of time synchronization devices is information about a time offset between the time synchronization device and an upstream time device, and the plurality of time synchronization devices are time synchronization devices on the synchronization path. The first network device calculates a time offset of the synchronization path based on the synchronization path information and the time offset information of the plurality of time synchronization devices (S403). The first network device may monitor an offset between time of each time synchronization device and time of the time source, so that accuracy of monitoring time synchronization is improved. In addition, no additional time source needs to be deployed, so that deployment difficulty is reduced.

摘要： This application discloses a clock port attribute recovery method, a device, a system, and a storage medium, and is applied to the field of clock technologies. The method includes: A network device sets a value of a port attribute of a clock port of the network device to a first value based on a case that the clock port does not receive any one of three types of clock messages: N synchronization messages, follow-up messages, and delay response messages within a timeout interval, where the first value indicates that a message is lost on the clock port. Based on a case that it is determined that a recovery condition is met, the network device sets the value of the port attribute of the clock port to a second value, where the second value indicates that a status of the clock port is that no message is lost.
