The diagnostic switch retains ALL the features of an unmanaged switch such as auto-negotiation and auto-MDIX except for one significant feature – it does not learn. Because it does not update its database of source MAC addresses and switch port pairings, the diagnostic switch continues to flood all ports with messages as if they were broadcast messages. This allows protocol tools such as Wireshark® to capture any network traffic that goes through the switch regardless of the port location of the traffic. The diagnostic switches are available in 5-port and 8-port models but can be cascaded if more ports are required.
The Skorpion Diagnostic Switch can be permanently installed on an installation or replaced with a regular Skorpion switch once a system is commissioned. This device can also be useful when developing embedded Ethernet devices because you can connect the Skorpion Diagnostic Switch between two embedded Ethernet devices and view their messages using Wireshark®.
The Skorpion Diagnostic Switch can be used for control panel installations where one needs the ability to diagnose problems in the field. It can also be used in a development environment when debugging code. A metal DIN-rail clip attached to the aluminum enclosure can survive the toughest installation.
