Abstract
The invention discloses a backup method of link status annunciation. The backup method comprises that a reserved board receives a first level shift amplifier (LSA) generated and sent by a main board, wherein the first LSA is sent after the main board records flooding information of the first LSA, and the flooding information is used for indicating that the first LSA is in a flooding state; the reserved board stores the received first LSA; and the reserved board replaces the main boar to conduct flooding treatment on the first LSA after storing the received first LSA to enable the main board to remove locally-stored flooding information of the first LSA after receiving confirmation responses aiming at the first LSA and returned from a neighbor device. The invention discloses a backup device. By means of the backup method and the backup device, when LSA backup is carried out, LSA desynchronized problems caused by LSA backup failures can be avoided, operation complexity of the main board can be reduced, LSA backup efficiency is improved, and load sharing can be achieved.
