Network Taps Next: ConclusionUp: Receive-only UTP cables and Previous: Receive-only cables Subsections The alternative. TAP stands for Test Access Port. Obviously, Network Taps are more expensive than making your own receive-only cables, but they have more advantages. There are several companies that develop these products. It is interesting to note that all Tap manufacturers claim their copper Taps are fail-safe (no disruption to the link on powerloss). Schemes The diagram 11 describes two ways to represent the Tap connection scheme. A Tap captures network traffic in both directions and sends it to a monitoring device, such an IDS or a statistics traffic generator. To build a Tap like that is trivial. More solutions for analyze traffic with Taps are discussed later on section 4.3 `Implementation Examples'. Adaptive Taps Adaptive Taps are designed to make signal conversions, in addition to capturing traffic. Regeneration Taps Aggregation Taps Taps versus Span (mirror) Ports Traffic integrity.
the 5-in-1 network admin's cable ethernet / crossover / modem / null modem / Cisco console featured in the premiere edition of Make There is nothing worse than showing up for an on-site visit without the correct cable you need for a job. For quite some time I've been carrying a single CAT5 ethernet cable in my laptop bag along with "the world's shortest crossover cable" and an RJ45 coupler. But after putting together four simple custom adapters, I now have an ethernet cable, a crossover ethernet cable, a modem cable, a null modem cable, and a Cisco console cable all by carrying around just one standard ethernet cable. Do you find yourself toting several of these cables everywhere you go? Here's how to make your own: RJ45 pin 8 has to connect to both 1 and 6 on the DB9 connector. Here's how to use it: DB9/RJ45 - ethernet - coupler - Cisco adapter Remember that the Cisco adapter is not reversible. Notes: This solution is somewhat similar to the Yost wiring standard which I have long found to be quite useful. Extras:
