## Description

Dualcomm ETAP-2003 i a Network Tap for ue with a 10/100/1000Bae-T Ethernet link. ETAP-2003 i olidly contructed with a metal cae and i probably the mallet in ize of all the GbE Network Tap available on the market. ETAP-2003 can be powered from a computer' UB port with built-in inruh current limiting circuit to prevent the computer from poible damage or diturbance by an intantaneou current urge when ETAP-2003 i being powered from a UB port of the computer. ETAP-2003 i compatible with \Power over Ethernet\ (PoE) o that deployment of an ETAP-2003 Network Tap would not block the end-to-end flow of PoE inline power which i a very ueful feature for monitoring or capturing data traffic of a PoE Ethernet link. A network monitoring and troublehooting intrument ETAP-2003 i highly reliable with conitence performance. It has been teted with the maximum in-line cable length of 200 m at a full 1Gbp data throughput with no ingle packet lo. All thee make ETAP-2003 an ideal portable network traffic niffing device for monitoring and troublehooting data traffic in a 10/100/1000Bae-T Ethernet network.

Review: Nice to have - Works great!
Review: Excellent "every day carry" tap - Great network tap for security/IT support use. Unlike many similar products this one preserves the MAC addresses of packets which is important for some applications. It's small and light enough just to keep in the work bag and USB power means no need to carry a separate power brick. It's not cheap, but good value if you need to do network snooping on a regular basis.

## Questions & Answers

**Q: Why this so much while a switch with port mirroring (e.g. tl-sg105e, if only utilizing 3 ports) only cost $20? with due repect to the manufacturer.**
A: A switch with port mirroring isn't a tap. The manufacturer of this tap did the work to design and implement a device which would NOT change the characteristics or timing of the A/B traffic flow. The design is not a  "standard cookie-cutter" implementation of a switch-chip's reference design. On the other hand, 5-port switches are as they say "a dime a dozen" and port mirroring and simple management protocols are now built into the silicon as standard features. 
Another reason for the price difference is the application. A tap is used in specialized circumstances, such as diagnostics or forensics, and that perhaps allows a higher price to be demanded, much like selling rope in a yachting goods store. The buying audience can bear a higher price.
My explanation is just a conjecture. You have to decide if the special tap features are worth the money.

**Q: Will it work with a cable modem?**
A: It will work with any Ethernet cable. Standard stuff. I recommend CAT6 or better. It will not work with a coax cable like RG6. It is not managed and provides no services like DHCP. It is a simple layer 2 switch with a hardware mirrored port (1 -> 5). It is permanently configured this way. If you want to capture packets on the wire going traversing a gateway, then this is great for that. Otherwise, it will act just like a regular un-managed switch.

**Q: If this device fails will it fail open or block all traffic?**
A: With no power, it will not pass traffic.

**Q: Thinking about by. Anyone who purchased notices any network degradation in their environment where they have implemented their Tap?**
A: We have not had any noticeable network degradation. We positioned out tap on our outgoing broadband connection (70/40 Mbps down/up) and have not had any deleterious effects.
