Network device configuration correcting method and network device

Abstract

The invention provides a network device configuration correcting method and a network device. The method comprises: the network device discovers a Link Layer Discovery Protocol (LLDP) message sent by a neighbor device; the network device analyzes the LLDP message to obtain the attribute information of the opposite-end interface of the neighbor device; the network device acquires the attribute information of the adjacent port of the neighbor device; the attribute information of the adjacent port is compared with the attribute information of the opposite-end interface; and if differential attribute information exists through the comparison, configuration correction is carried out on the interface corresponding to the differential attribute information according to a preset rule. By utilizing the network device configuration correcting method and network device provided by the invention, the automatic configuration correcting can be realized when the port configuration is detected to be incorrect, so that the stability and reliability of the network are improved.

Description

technical field [0001] The invention relates to network technology, in particular to a method for correcting configuration of network equipment and network equipment. Background technique [0002] Ethernet is currently the most common communication protocol standard adopted by the existing LAN, and the three-layer Ethernet network is the most widely used Ethernet topology. figure 1 It is a three-layer Ethernet network topology diagram. like figure 1 As shown, a three-layer Ethernet network includes a core layer, an access layer, and an aggregation layer. Among them, the number of access layer devices and aggregation layer devices is relatively large due to user considerations and redundancy backup considerations, and in order to ensure The connection between them is stable and secure, and the connection relationship between the access layer device and the aggregation layer device is also very redundant. Therefore, it brings huge challenges to network management and config...

Problems solved by technology

Therefore, it brings huge challenges to network management and configuration, and it is often impossible to detect connection link problems between devices in the first time

For example, the link of a member port of an aggregation port (the interface between the aggregation layer device and the access layer device) is disconnected, but the links of other member ports are normal, so from the appearance, the aggregation port is still connected. It is in a normal state, but at this time one of the member links has been disconnected, which has caused hidden dangers to the stability and security of the network

[0003] In the prior art, the network device usually compares whether the configurations of two or more neighboring devices are consistent with it. If not, it is considered that there is a connection error. At this time, the administrator is prompted in syslog mode to allow the administrator to check and modification, or the port is directly closed by the network device, which will cause network failure
