Dualcomm ETAP-2003 10/100/1000Base-T Gigabit Ethernet Network TAP

This thing is cool! A must have for a network engineers toolkit. I cant rely on customers to be able to setup mirror ports, so for troubleshooting this is a great tool. I may only use it once in a while but it will be a lifesaver in the right situation. Ive tested it out and it works as anticipated - especially useful for sniffing VOIP phone traffic with the POE passthrough.

Perfect. A little bit more expensive due to its metal casing.

Dualcomm makes great devices and it met my needs to practicing with the Wireshark software. Excellent device! Worth the every penny!

This makes my job much easier but make sure you have the right one for the job. I wanted to be able to tap into a camera feed to view the picture and this model does not do that but Dualcomm does have one that will. When I couldnt get it to work I called Dualcomm and they where great to work with and made sure I got the one I needed.

Muy buen equipo, imprescindible

It just works. what ever ingresses and egresses port 1 will egress port 5. I connect a computer with Wireshark to port 5 and let the fun begin.

Works great! Ive been using it to monitor all the traffic on my home network and its been very reliable. Currently sits between my modem and router and causes no slow downs or latency problems. My internet speeds get up to 250Mb/s.

Simple, no hassle, does what I expected. I prefer to plug it into a USB power adapter so not to confuse my simple-minded XP machine regarding an unexpected USB device.

... I think the last time I was this excited about a network device I was 13 years old and my mom got me a 2400 baud modem for my birthday. The unit works exactly as described, it mirrors port 1 to port 5, leaving the remaining 3 ports as regular switched ethernet ports (though port 2 is also the PoE passthrough, which I havent had the chance to test to that extent). It couldnt be more straight forward than it is. The USB power is fairly cool, I can imagine it being very practical when youre near a server rack trying to sort stuff out. Right now Im actually using an iphone wall socket to power the unit since my router and switch is rather far away from my workstations. Works just fine. But I see a soldering iron in my future if/when that cable breaks (still beats scavenging ebay for a compatible power supply, waiting for it to be delivered, etc). The manual is...well...a single page that describes the device. There is no setup instructions or common scenarios, nothing. And thats ok, this isnt for the uninitiated anyway. If you cant figure out how to connect a switch tap youll never get wireshark display filters to work for you anyway... 5 star for price, features, ease of use and I could ding them for the manual, but I wont. Its fine the way it is.

The item was as described and was up and running right out of the box. Just what I expected
