LANProbe is a non-intrusive handheld or mountable inline device used to monitor Ethernet traffic on a gigabit network to help administrators identify issues or analyze network anomalies. It does this by “tapping” into between two devices using ports 1 & 2. It functions by way of port mirror on a switch. Then the network data passing through ports 1 & 2 is duplicated/mirrored to both ports 3 & 4 for analyses using a PC. An analysis software on a PC such as Wireshark or tcpdump may be used by an administrator to inspect the packets. The LANProbe offers the ability to bypass itself in case of power failure to allow port 1 through port 2 connectivity. This feature helps capture network data with minimized impact to the data being monitored.
