We have a Cisco 3750 that has a span port setup, to mirror traffic from all the other ports. Right now we have our IDS connected to that span port. But we now have a need to have a second device see that same traffic. In the old 10/100 days we could probably have used a hub.
But in a gigabit world, how do I let two devices see that span traffic? I found some gigabit taps, but they seemed to be designed to sit inline between two devices, not necessary to just duplicate a single port (which would come from my SPAN). But maybe they would work anyway?
