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.

Faulty multi-layer link restoration method and controller

A method, a system, and a device for establishing a pseudo wire are disclosed. The method includes: receiving, by a switching provider edge at a bifurcation position, a label mapping message, obtaining information of the switching provider edge at the bifurcation position and information of at least two next hops or outgoing interfaces of the switching provider edge through parsing, comparing the information of the switching provider edge at the bifurcation position with information of a local device, and if the information of the switching provider edge at the bifurcation position matches with the information of the local device, establishing at least two pseudo wires from the switching provider edge according to the information of at least two next hops or outgoing interfaces.
