Disclosed are a method and device for triggering protection switching by signal degrade of a link aggregation port, wherein the method includes: acquiring status information of member ports of a link aggregation port from a status register of the link aggregation port; obtaining a number value X of member ports of the link aggregation port which generate signal degrade light path attenuation according to the acquired status information of the member ports; comparing the obtained number value X with a predetermined threshold value; and when the number value X is greater than the predetermined threshold value, setting statuses of all the member ports of the link aggregation port to be a signal degrade status, and notifying a virtual section layer to report fault and perform a service protection switching to a backup link.
