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: A method for enabling multicast forwarding relates to the field of IP communication technologies. The method for enabling multicast forwarding implements flexible networking and enables proper function of the multicast proxy. A switch device receives a multicast protocol message; the switch device determines a sender of the multicast protocol message according to a port from which the multicast protocol message is received; the switch device transmits the multicast protocol message transparently if the sender of the multicast protocol message is a routing device or a switching device, and the switch device terminates 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.
