Abstract
Embodiments of the present application provide a master and backup election method and device, and relate to the technical field of cross-device link aggregation. In the method, an M-LAG system includes a first M-LAG device and a second M-LAG device. The first M-LAG device acquires a first total oscillation number of physical interfaces on the first M-LAG device and acquires a second total oscillation number of physical interfaces on the second M-LAG device. If the first total oscillation number is greater than the second total oscillation number, the first M-LAG device is determined as a backup device again, and the second M-LAG device is determined as a master device. The scheme can improve the availability of M-LAG system services.
