Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A troubleshooting method, comprising: determining, by an aggregation node when a link fault or a device fault occurs on an active optical line termination OLT side, an active logical port used by the active OLT to forward a data packet, wherein the active logical port supports at least one user service, and each user service is denoted by a user service identifier (C-VLAN, S-VLAN) formed by a user local area network tag C-VLAN and a service local area networ…
