SharkTap Network Sniffer The SharkTap is a special purpose 10/100Base-T ethernet switch that allows you to 'tap into' an ethernet connection. It is intended to be used with the open source Wireshark network analyzer or equivalent. Conventional switches route packets only to the intended destination port, reducing traffic, but preventing a third port from seeing all packets. The SharkTap sends a copy of all packets on the 'NETWORK' ports to the 'TAP' port. Powered from a micro-USB cable (included), draws 250mA or less. Other features: Passive technology will not alter NETWORK traffic, even with power off.
