You keep talking about crossover cables and MDI/MDI-X, but the topic is creating a *tap*. That has nothing to do with crossover cables and MDI/MDI-X but with how to listen to traffic without affecting it. That cannot be done with a passive tap for gigabit ethernet because of the reasons that Gert mentioned.

Cheers,
Sander
