    Abstract: The method is applied to an SDN network, where the SDN network includes one target computing apparatus and a plurality of openflow switches. The target computing apparatus communicates with the plurality of openflow switches. The method includes: receiving, by the target computing apparatus, a first bridge protocol data unit (BPDU) packet sent by a first openflow switch, where the first BPDU packet carries a device identifier and a port identifier; generating, by the target computing apparatus, a feedback packet based on the first BPDU packet, where the feedback packet includes spanning tree protocol information of a conventional switching device, and carries the port identifier; and sending, by the target computing apparatus, the feedback packet to the first openflow switch based on the device identifier.

    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: The present application provides a method and a device for clearing a MAC forwarding entry. The method includes: detecting, by a first RB, that a topology of a network accessed by a local terminal changes; and sending, by the first RB, a first packet to a second RB, so that the second RB clears a corresponding forwarding entry after receiving the first packet, where the second RB refers to an RB configured with at least one VLAN the same as that of the first RB. According to embodiments of the present application, after the topology of the network accessed by the local terminal changes, MAC forwarding entries of relevant devices in a whole network can be cleared in time, thereby avoiding a forwarding error.
