Abstract
Embodiments of the present invention disclose a troubleshooting method. The method includes: determining, by an aggregation node when a link fault or a device fault occurs on an OLT side, an active logical port used by the active OLT to forward a data packet; searching, by the aggregation node, a locally stored logical port mapping table according to the active logical port to obtain a standby logical port corresponding to the active logical port, where the standby logical port supports a same user service as the active logical port; and triggering, by the aggregation node, the standby OLT to enable the standby logical port to receive a data packet that is sent by the standby OLT through the standby logical port. The implementation of the present invention can provide utmost compatibility with the live network and enable a communication link to recover from a fault quickly.
