Abstract
In a troubleshooting method, a controller first determines that a fault occurs on a first multi-layer link passing through a first port on a first network device, where the first multi-layer link is a link in a link aggregation group between the first network device and a second network device. The controller then releases an optical layer resource of the first multi-layer link, and deletes the first multi-layer link from the link aggregation group. The controller further establishes, a second multi-layer link for restoration of the first multi-layer link, based on a first idle port on the first network device and a second idle port on a target network device, and adds the second multi-layer link to a target link aggregation group between the first network device and the target network device.
