Dualcomm USB Powered Network Tap (Model No. DCSW-1005)

I love this device. It has helped a lot during troubleshooting and network solving actions. Very recommended.

Plug and play, no issues. I needed to monitor the communication between two micro controllers , and poll one of them from my PC at the same time. I plugged the micro controllers in ports 1 and 2 (with the one being polled in 1), and my PC in port 5. Everything worked beautifully as I intended. The small size and being powered from USB are definitely good features.

Works perfectly as a TAP to use for Wireshark troubleshooting Ethernet-connected products. Connect one of the ports to the device you wish to monitor, another of the ports to the network, and a 3rd port to your computer running Wireshark in "Promiscuous Mode". The only real challenge is identifying which of the 5 ports you need to use for the 3 aforementioned purposes. Suggestion... Read the directions carefully, get it working, and then use a label maker or permanent marker to mark the ports so the next time you use the product you don't need to re-read the directions. Overall, great product at much lower cost than comparable dedicated TAPs.

1st one received had a dead port 5. No LED, no port mirroring data. I posted a question on Amazon and got an answer from Dualcomm within around an hour confirming it wasn't working right. I overnighted a 2nd one and it's working great for port mirroring. I'm not using PoE so no feedback there. Mechanically, both appeared well built. My advice would be to buy it, try it, and have it ready in your tool kit before you need it in case you get a out-of-box failure like I did. Great customer service from Dualcomm and Amazon!

I support many different VOIP manufacturer products and constantly need wireshark captures of issues. Often times techs in the field can't/wont/don't have the ability to provide captures for troubleshooting. This device is perfect for grabbing wiresharks on your laptop since it's USB powered. Telephone guys.... THIS IS A IP BUTTSET. It's an invaluable tool for troubleshooting anything IP. Every tech should have two in the bag at all times. You often need to run two captures at the same time to compare what's happening on a particular network segment. Interconnect owners! You have no problem buying a $300 butsett for a guy... buy two of these. I guarantee it will save tech hours onsite troubleshooting the customer network.

As a network engineer, who generally works on contract to multiple clients, I find this product indispensable. When I need to port mirror a network connection and I either don't have access, or privileges, to configure the device I can plug this tap in line and connect my packet sniffer to the mirror port to troubleshoot failures. This product is inexpensive, functional and DA BOMB!!

Saying it has a tap feature is false advertising. A tap should be absolutely passive, it shouldn't be physically possible for it send traffic. This is basically a switch with port mirroring fixed configuration.

Works as advertised, although it sometimes shut my laptop off it running from battery, I suppose because of power draw. Still, very handy and great for packet captures.

Was gefällt mir? Die Funktion. Was nicht? Der Preis. Genau genommen nutze ich damit nur die Funktion die früher jeder HUB hatte. Was will ich meckern....tut was es soll.

I find it somewhat funny seeing that these "monitoring" tools are now somehow special since we used to have Ethernet HUB everywhere couple years ago. But since I did not find Hub from anywhere this will have to do. Sure it is very usefull tool with Wireshark. I managed to monitor Modbus TCP traffic withot any issues.
