Abstract: 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 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, 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; and when monitoring 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 smaller than or equal to N.

Abstract: Embodiments of the present invention relates to the field of IP communication technologies, and disclose a method, a switching device and a system for enabling multicast forwarding to implement flexibly networking and enable the multicast proxy function correctly. The method includes: receiving a multicast protocol message; determining a sender of the multicast protocol message; transmitting the multicast protocol message transparently if the sender of the multicast protocol message is a routing device or switching device; and terminating the multicast protocol message according to a multicast proxy function if the sender of the multicast protocol message is a host of a multicast user.
