Problems solved by technology

Then, the data monitoring device may not be able to find abnormal conditions based on the received packets. For example, when the source device (the device where the mirror source port is located) is attacked, the mirror source port frequently sends illegal packets, causing network abnormalities. , and the remote port mirroring technology cannot effectively locate the cause of network anomalies

Abstract

The invention provides a remote port mirroring realization method and device. The method comprises the steps of receiving a mirroring message sent by a to-be-monitored device; redirecting the mirroring message to a destination port according a preset strategy when it is determined that the mirroring message is an illegal message; and sending the mirroring message to a data monitoring device through the destination port. Through application of the method provided by the invention, the network data can be monitored and analyzed effectively, and the cause of a network abnormity can be effectively positioned when the network is abnormal.

Description

technical field [0001] The present application relates to the technical field of data communication, in particular to a method and device for realizing remote port mirroring. Background technique [0002] Port mirroring is a method of copying packets from one or more ports on a switch or router to one or more other ports. The port where the packet is copied is called the mirroring source port, and the port that receives the copied packet is called the source port. Mirror destination port. The mirroring destination port can transmit the received messages to the data monitoring device, so that the data monitoring device can monitor and analyze the messages of the mirroring source port based on these messages. Port mirroring can be divided into local port mirroring and remote port mirroring according to whether the mirroring source port and the mirroring destination port are located on the same device. For example, when the mirroring source port and mirroring destination port ...
