SharkTapBYP network sniffer

What is a "Network Sniffer"?

A network sniffer, also known as a network Test Access Port (TAP), allows the user to view the data on an ethernet link. The SharkTap sniffers support 10, 100, and 1000Base-T links, which use copper cables. Packets flowing through the NETWORK ports are duplicated to the TAP port. The TAP port is typically connected to a PC running Wireshark. or similar software. The SharkTaps leverage the economies of scale of standard switch chips, allowing me to provide serious test equipment at a very attractive price. The switch chips in the SharkTap family support "port mirroring". The SharkTaps are what CISCO calls a SPAN port. They are sometimes also called aggregating taps since both NETWORK ports are mirrored to one TAP port. https://en.wikipedia.org/wiki/Port_mirroring All SharkTaps also have "auto-MDIX" which means that you never have to worry about CAT-5 crossover cables. All ports will work with either a straight-through or crossover cable.

The SharkTapBYP is ideal when you need the extra security of a fail-safe link but don't need a high-end carrier-grade TAP. The SharkTapBYP is ideal for embedded data acquisition applications where the SharkTap will be installed permanently.

• A power-fail bypass
• If power fails, relays automatically restore a direct connection between the Network ports. (actually, a transformer-coupled connection, so PoE is not interrupted)
• The bypass relays do not draw idle power and do not break PoE on power-up or power-fail
• Dual power for further security: Power from a USB3 port (blue insert) and/or A/C adapter (like a phone charger). A USB2 port is adequate if you're only using the wired TAP port (not the USB TAP). USB3 and USB2 cables are included.
• The micro-B connection only takes power and does not make a USB connection to your PC.

Simple plug and play

• Two "use cases" - a wired TAP port or a virtual USB NIC
• For bench use, power from a spare USB port - does not make a USB connection, only uses power.
• You'll need a CAT-5 (or equivalent) patch cord or two (not included)
