    摘要： Provided are a method and device for processing RPF line detection. The method includes that: it is detected whether communication quality parameters of an RPF line exceed a preset range; when the detection result is yes, it is analyzed whether the reason causing the communication quality parameters of the RPF line to exceed the preset range is power supply noise; when the analysis result is yes, the power supply of the RPF line is cut off or the power supply cut-off state of the RPF line is maintained, and the analysis result and/or processing result of the RPF line are/is reported to a network management system.
