The invention provides a configuration synchronization method and device. The method comprises the following steps of establishing a DR system with a second network device enabling DRNI; when the first network device is a main device of the DR system, determining a configuration command for enabling a DR interface according to a received configuration issuing instruction; and synchronizing the configuration command enabled by the DR interface to the second network device, so that the second network device issues the corresponding configuration to the DR interface of the second network device according to the configuration command. By applying the embodiment of the invention, the complexity of the networking deployment can be simplified, and the performance cost of the DR device is reduced.

Embodiments of the invention provide a loop processing method, network equipment, an MLAG ad hoc network, and a storage medium. Main equipment and standby equipment in the MLAG ad hoc network send loop detection messages through other ports except a heartbeat port, so that loops in the MLAG ad hoc network can be detected. When the main equipment receives the loop detection message sent by itself or the standby equipment, loop processing is carried out on the ports sending out the loop detection messages. The heartbeat port does not send the loop detection message, and when the loop processingis carried out on the loop detection messages, the heartbeat port cannot be processed, so that the situation that the heartbeat port is blocked due to the loop processing of the heartbeat port can beavoided when the loops of the MLAG ad hoc network are eliminated, and the failure of the MLAG ad hoc network can be prevented.

The present application provides a device virtualization method, an apparatus, a system, a device, and a storage medium. The device virtualization method comprises: determining virtual information of a virtual device according to device information of a local device and device information of a peer device of a multichassis link aggregation group, wherein the local device and the peer device are multiple first devices of the multichassis link aggregation group, the device information comprises a network bridge identifier and a port identifier, and the virtual information comprises a virtual network bridge identifier and a target port identifier; exchanging an extension protocol packet with the peer device, wherein the extension protocol packet is generated on the basis of a spanning tree protocol packet received by the local device; and determining a role and a state of a port of the local device according to the virtual information and the extension protocol packet of the peer device in combination with a protocol packet received by the local device.

The invention provides an equipment starting communication and data transmission method, device and system, and the equipment starting method is used for first equipment, and comprises the steps: receiving a first message which is used for detecting a link state between the first equipment and second equipment; judging whether the first message is sent by second equipment or not; when the first message is sent by the second equipment, the first equipment starting communication, and emptying a message timer of the first equipment; and forwarding the first message to the second device to enablethe second device to start communication, and emptying a message timer of the second device. By the disclosure, when the first equipment starts communication, the message timer is emptied and the first message is forwarded to the second device, so that the second device starts communication at the same time, the communication starting time difference caused by asynchronous starting of the physicalport between the first device and the second device is eliminated, and the problem of data packet loss caused by large time difference is avoided.

The disclosure relates to a port state setting method and device. The port state setting method comprises the following steps: receiving a first BPDU message, and receiving a second BPDU message; judging whether the senders of the first BPDU message and the second BPDU message are the same device or not in the case that the bridge identification code carried by the first BPDU message is the same as the bridge identification code carried by the second BPDU message, so as to obtain a judgment result; and controlling the state setting of the port receiving the first BPDU message and the port receiving the second BPDU message according to the judgment result. Through the port state setting method and device disclosed by the disclosure, the defect that a tunnel used as an IPL link in DRNI networking without Peer-Link is blocked by a STP protocol can be avoided, therefore, the smoothness of the IPL link is ensured, the normal and effective operation of a DR system is ensured, and the stability of the DR system is improved.
