Network loop monitoring method, system and device and storage medium

Abstract

The embodiment of the invention provides a network loop monitoring method, system and device and a storage medium, a loop frame message is received and inserted at a CPU channel interface end, the loop frame message is broadcasted to a network from each signal sending port by using forwarding and broadcasting functions of a switching device, and when a loop occurs in the network, the loop frame message is sent to the switching device. And the loop frame messages are finally returned to the switching equipment serving as the sending equipment. Therefore, the message broadcasted in the network is received in real time at each signal receiving end of the switching equipment, meanwhile, the received message is detected, whether the message belongs to the message sent by the equipment or not is judged, and an alarm is given to the generated loop, so that the switching equipment can take some measures for blocking the occurrence of the loop. According to the embodiment of the invention, loop detection of multiple ports of the switch is realized, loop detection and positioning in a network can be quickly realized, and a network storm caused by a network loop is avoided.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to a network loop monitoring method, system, device and storage medium. Background technique [0002] Today's switching network environment is composed of a large number of switching devices. When these switching devices receive a message frame with an unclear purpose, they often need to broadcast the message from other ports to obtain the destination device address. However, due to the complexity of the networking of network devices, loops will inevitably occur when packets propagate on network links. When loops occur in broadcast packets, the impact is often huge. These broadcast packets Unlimited broadcasting of text on the network will occupy a large amount of network bandwidth and eventually lead to network paralysis; therefore, it is particularly important to detect and prevent loops on the network.
