The present invention provides a method and a system for detecting a Signal Degrade (SD) alarm. The method comprises the following steps: a transmitter-side device determines that service traffic transmitted from a first port of the transmitter-side device to a second port of a receiver-side device is lower than a first preset threshold; the transmitter-side device transmits background traffic to the second port through the first port; and the receiver-side device performs an SD alarm detection according to traffic received on the second port.. The present invention achieves the effect of reducing SD alarm vibration. |
