LACP LINK SWITCHING AND DATA TRANSMISSION METHOD AND DEVICE

摘要

Embodiments of the present invention provide a method and a device for link aggregation control protocol (LACP) link switch. The method includes: monitoring state changes of interfaces in an LACP link aggregation group; when monitoring that a state change occurs on an active interface in the aggregation group, determining whether the number of active interfaces in the aggregation group is smaller than a preset minimum active link number, and if yes, keeping states of N interfaces among the interfaces on which a state change occurs being an active state, so that the number of active interfaces in the aggregation group is greater than or equal to the preset minimum active link number , N being a natural number and N being smaller than or equal to the number of interfaces on which a state change occurs, among the active interfaces in the aggregation group; and when monitoring that a state change occurs on an inactive interface in the aggregation group, adjusting states of M interfaces among the N interfaces kept in the active state into an inactive state, M being a natural number and M being smaller than or equal to N.
