Abstract

The invention discloses an Ethernet fault positioning and detection method which is used for positioning and detecting faults of network devices in a target network. The method comprises the following steps: network device state consistency detection, network device congestion abnormity detection, link packet loss abnormity detection and positioning, target network DoS attack detection and address forwarding table correctness detection. Compared with the prior art, the Ethernet fault positioning and detection method can detect and position Ethernet faults by searching standardization-based switch-supported SNMP and MIB-2 at present and then by carrying out simple calculation, so that the Ethernet fault positioning and detection method is simple and practical, has better applicability and engineering applicability, and has higher efficiency and accuracy.

Description

technical field [0001] The invention relates to the technical field of network system fault maintenance, in particular to a method for locating and detecting Ethernet faults. Background technique [0002] As more and more Internet applications are integrated into people's daily life, people have higher and higher requirements for network user experience. Keeping the network unblocked in real time is a prerequisite for ensuring user experience. Therefore, it is necessary to detect, locate and eliminate network faults in a timely manner. Therefore, the detection and removal of network faults is a very important part of network management. Therefore, how to efficiently and accurately locate and detect network faults has become a hot and difficult point in network fault research in recent years. [0003] At present, the main methods of Ethernet fault detection are: establishing a dependency graph or a module dependency graph between network communication entities, and then dete...
