  • Publication number: 20230096052
    Abstract: An alarm processing method and apparatus is disclosed. Specifically, a mechanism of configuring and detecting an LOF pre-alarm is provided. A detection condition of the LOF pre-alarm is that it is detected that a frame alignment failure lasts for first duration. A detection condition of the LOF alarm is that it is detected that a frame alignment failure lasts for second duration. The second duration is less than the first duration. When detecting the LOF pre-alarm, a network device inserts a first maintenance signal frame. The first maintenance signal frame supports frame alignment. In other words, a network device that receives the first maintenance signal frame may perform normal frame alignment, so that no alarm is reported, for example, the LOF alarm is not triggered.
