Embodiment Construction

[0092] In a complex network environment, network failure is an inevitable problem. For example, in Ethernet communication, in order to improve the reliability of the network, redundant links are usually used, but the use of redundant links will cause problems in the switching network. Loops cause data link layer packets to be cyclically forwarded in the network, resulting in network paralysis. In order to prevent the loop problem in the switching network, spanning tree protocol (spanning tree protocol, STP) is applied in the network, and the network selects the root bridge in the network, the root port of each non-root bridge, and each The designated ports of non-root bridges block the non-designated ports of each non-root bridge, so that the physical mesh topology can be transformed into a logical tree topology, so as to eliminate network loops and prevent broadcast storms from occupying a large number of switches H.

[0093] When the network is running STP, the election of ...

Abstract

The embodiments of the application disclose a network fault positioning method. The method comprises the following steps that: a network device detects a fault and determines a fault cause; the network device generates a fault packet according to the fault cause, and sends the fault packet to a fault analysis device; and the fault analysis device receives the fault packet sent by the network device, obtains the fault information corresponding to the fault packet, and determines that the network device is a target device if the fault information meets a preset condition. According to the network fault positioning method, a related device, and a computer storage medium, the problems that the positioning is inaccurate, the efficiency is low, and the like when the network fault caused by a spanning tree protocol is artificially analyzed are solved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a network fault location method, related equipment and computer storage media. Background technique [0002] With the rapid development and wide application of network technology, communication technology has been applied to various fields of human activities. During the operation of the network system, various network failures often occur. When a failure occurs, how to find the cause of the network failure in time and determine the location of the network failure has become a practical problem in front of the managers and technicians. Therefore, for The research on network system fault monitoring technology is of great significance. [0003] At present, in a Layer 2 network, switches run Spanning Tree Protocol (STP) to eliminate loops in the network and avoid broadcast storms caused by the existence of loops. In a network running STP, when a The original root bridge fre...
