Problems solved by technology

In the prior art, in order to solve the above problems, the FDB table is synchronized from the hardware to the software, but if the network management server obtains the FDB information during the synchronization process of the FDB table, it will cause the network management server to wait for a long time and eventually cause the information acquisition to time out, thereby Unable to obtain network device connection information

Abstract

The present invention provides a method and device for obtaining network device connection information. In the method, the network node device receives the request for obtaining the FDB forwarding table sent by the network management server, and at least two FDB forwarding tables currently saved by itself are in an active state. The first FDB forwarding table is sent to the network management server. Because there are at least two FDB forwarding tables in the network node device in the embodiment of the present invention, when the network node device provides the FDB forwarding table to the network management server, the first FDB forwarding table that has been updated in an active state is provided to the network management server, In this way, the problem of long-time waiting caused by the long-term waiting of the network management server is avoided.

Description

technical field [0001] The invention relates to the technical field of industrial Ethernet, in particular to a method and a device for acquiring connection information of network equipment. Background technique [0002] In the local area network, in order to be able to manage network nodes in real time and better ensure the stability and security of the network, it is necessary to obtain the topology of network devices in a timely manner, that is, the connection information between network devices. The connection information of the network is calculated and generated through the topology discovery protocol to generate a network topology map. Link Layer Discovery Protocol (LinkLayer Discovery Protocol, LLDP) is a commonly used topology discovery protocol. LLDP defines a general announcement information set, a protocol for transmitting announcements, and a method for storing received announcement information. The device with its own information can transmit multiple pieces of...
