But these are very raw data, just basic events about the addition and removal of devices, not the details of where these devices are or how they operate with network services, that is, there is no second layer information, which leads to the establishment of network management systems. Network topology is not accurate enough

Embodiment Construction

[0021] Layer 2 Discovery drills down to information such as which devices are attached to which ports, and which switches are connected to each other, and shows the connections between clients, switches, routers, and application servers, as well as network servers. Path, these detailed information will be very meaningful for planning and querying the root cause of network failure. Through the link layer discovery protocol, it enables the device to notify its neighbors of its status information, and each port of all devices stores the information defining itself, and can also send it to the neighbors directly connected to them if necessary Updated information, neighboring devices will store the information in standard SNMP (Simple Network Management Protocol) MIBs (Management Information Bases). The network management system can query the current connection status of the second layer from the MIBs. LLDP does not configure nor control network elements or traffic, it just report...

Abstract

The invention provides a method of obtaining network connection information using a link layer finding protocol, comprising: transmitting link layer finding protocol message to other devices by a device, wherein the message is carried with local device information in the device; receiving the link layer finding protocol message from other devices by the device, resolving the link layer finding protocol message, composing a far-end network device information according to the local device information carried therein, storing the far-end network device information in the device; storing the far-end network device information stored locally into a link layer finding protocol management information base. The invention performs network information performs network information double ply through using LLDP protocol, stores neighbor network information in LLDP MIBs, used for network management software unified finding, thereby ensuring network mapping discovery between isomerization network, advancing accuracy of plotting topology by network management software.

Description

technical field [0001] The invention relates to the field of data product switches, in particular to a method for acquiring network connection information in a network management system according to LLDP (Link Layer Discovery Protocol, Link Layer Discovery Protocol). Background technique [0002] At present, many network management software use the "Automated Discovery" function (Automated Discovery) to track topology changes and conditions, but most software only reach the third layer at most, grouping devices into various IP subnets. But these are very raw data, just basic events about the addition and removal of devices, not the details of where these devices are or how they operate with network services, that is, there is no second layer information, which leads to the establishment of network management systems. The network topology is not precise enough. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a me...
