Fault diagnosing method and device

Abstract

The invention discloses a fault diagnosing method which comprises the following steps: an initiating node sends a topological message to a terminal node through a corresponding path and acquires first topological data according to the sent topological message; the terminal node acquires second topological data according to the received topological message; the initiating node acquires the second topological data from the terminal node through the corresponding path; and the initiating node conducts fault diagnosis according to the acquisition result of the first topological data and the acquisition result of the second topological data. In the invention, automatic diagnosis course of communication fault between plates is realized, with full automation, and without manual intervention.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a fault diagnosis method and device. Background technique [0002] In current communication equipment, a multi-board design structure is usually adopted, and information exchange is performed between each board through an inter-board communication channel. Wherein, on a communication device, an inter-board communication channel is a path for exchanging information between individual boards, and consists of a group of nodes and links connecting these nodes. [0003] like figure 1 As shown, it is a multi-board design mode corresponding to the main control board and the line card board, wherein there may be multiple main control boards, and each main control board can be connected to multiple line card boards through the inter-board communication channel. [0004] During the operation of communication equipment on the network, if there is an inter-board communication failur...

Problems solved by technology

[0008] However, when using the command line to determine the fault point, maintenance personnel need to be trained to master the command line provided during the test; the command line requires manual operation, and the command results also need to be manually confirmed. For simple faults that are easy to recover, manual testing is also required. Intervention, automatic recovery cannot be achieved

And if the fault causes the communication device to restart, the problem environment will be destroyed. At this time, the problem cannot be located using the command line
