My lab network connection is about to be upgraded fro 10-HDX to 100-FDX.
I started thinking about how to implement my IDS tap on the new network...
Right now, I just have a "dumb" hub in the link. This creates a collision
domain for the uplink. I'd like to eliminate this.
I have not looked for one in a year or so, but does anyone know of a
commercial product that would let me "tap" the new 100 Mbit link
without creating a collision domain? I'd hate to have to buy a
Cisco switch, and put one port in SPAN mode just to see the traffic
on this link! I have not seen any el-cheapo switches that allowed
anything similar to "span-mode" operation (but again, I have not been
following product announcements for the past 18 months).
