Abstract

An embodiment of the invention provides a communication fault detecting method, a communication fault detecting device and a communication fault detecting system, and relates to the field of communication. The problem that an LAG in the prior art cannot detect fault ports which operate abnormally is solved; and the risk caused by the reason that data are transmitted by the fault ports is avoided. According to the scheme, detecting equipment respectively acquires detection results of N ports in X servers; the detection results comprise wrong package data and lost package data, which are determined by each port, of another port according to received detection information transmitted by the other port; the detecting equipment determines the state of a first port according to the wring package data and the lost package data, which are determined by each port, of the other port; the state of the first port is used for judging whether the first port is failed or not; and the detecting equipment generates a fault notification of the first port according to the state of the first port.

Description

technical field [0001] The present invention relates to the communication field, in particular to a communication failure detection method, device and system. Background technique [0002] In the network construction technology, various server port aggregation and switch stacking methods are usually used to improve the reliability of the network plane. However, after port aggregation and switch stacking are performed in various servers, each port in the server may be unavailable due to some faults, which in turn leads to unavailable communication paths between the ports. [0003] In the prior art, the LAG (Link Aggregation Group, Link Aggregation Group) in the server can periodically detect the status of its own port, and when the port is unavailable, the server will ), remove unavailable ports from the LAG to switch communication paths. Such as figure 1 As shown, when port 1 of server 1 is unavailable and ports 2, 3, and 4 are running normally, port 1 is removed from the...
