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

Perfect tool, it has saved me a lot of time troubleshooting network issues.

I found the DCGS-2005L to perform exactly as advertised. It is straightforward to set up and use. Its small size and weight make it a good addition to a IT persons go-bag. My one complaint, and why the 4 instead of 5 stars is that; Fot the price they could have thrown in a wall wart. Otherwise I think it was a good value.

Perfect tool for finding pesky problems when you dont have a switch you can trust to mirror a port.

Considering most search results get you 1Gbps aggregiate taps for $750+ this tap is a steal. This tap works great and its easy to use. The USB power cable is handy and convienent since you dont need to carry a power brick around. In my case I have it mounted on the top of my laptop via velcro.

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.

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.

When I started doing my research for network taps I was surprised at the expense. It seemed that many products were over $500. What was I missing? It seemed like such a small thing to do, just like the old hubs. For my application, I needed a passive tap because it was going to be used to feed a network intrusion detection system (NIDS). Sure, I could have mirrored a port on my cisco switches, but I didnt want to lose any packets. The Dualcomm Gigabit Network TAPs price point made the purchase a no-brainer when comparing other products. When I received the product it was extremely simple to setup. No software configuration necessary. A simple passthrough from ports 1 to 2 with port mirroring on port 5. It doesnt get any easier than that. The system has been working great and has been successfully transmitting packets to my NIDS. Ive already detected several worms on my internal workstations. It is hard to put a price on that. I recommend the product and dont have any complaints.

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.
