## Overview

The Dualcomm DCGS-2005 is a portable, USB-powered network TAP designed for 10/100/1000Base-T Ethernet links.

With gigabit speeds and a built-in 4-port switch, it’s an essential tool for professionals needing reliable, on-the-go network monitoring and troubleshooting.

## Description

Dualcomm DCGS-2005/DCGS-2005L is a Network Tap for use with a 10/100/1000Base-T Ethernet link. Its portable size and being USB powered make it an ideal network traffic sniffing device for monitoring and troubleshooting data traffic in a 10/100/1000Base-T Ethernet network. DCGS-2005/DCGS-2005L further supports PoE inline power pass-through between the two inline ports, which is a very useful feature for capturing traffic of packets on a PoE link segment as DCGS-2005/DCGS-2005L does not block the flow of PoE inline power. DCGS-2005/DCGS-2005L can also be used as a 4-port 10/100Base-T Ethernet Switch. DCGS-2005 and DCGS-2005L have the same functionality. The only difference is that DCGS-2005 is enclosed in a metal case and DCGS-2005L is enclosed in a plastic case.

Review: Fantastic bit of kit for troubleshooting networks - Fantastic bit of kit for troubleshooting networks. Used on a daily basis for troubleshooting embedded systems. It's very useful being USB powered as you can run without mains power (handy when you've only got your laptop). It's saved me a fortune in time. The small netgear managed switches can be set up to do a similar thing at a lower cost, but they need mains, and don't have PoE Pass-Through.
Review: This switch works great for troubleshooting network issues with Wireshark or packet capturing software. It runs at gigabit speeds and was easy to get working. It has POE (power over ethernet) pass-thru on 2 ports. Port #1 is mirrored to port #5. To capture packets connect your other switch to port #1 and your capturing computer to port #5. It is powered by USB so no need to lug around a power adapter.

I had a slight data loss problem when using this tap. This data loss stopped when I swapped in the Datacomm etap-2105 (using the same cables and test equipment).
