Stefan, I think you're confusing your OSI layers here, routers route and switches switch.
If you're spanning 300 megabits per second, what you'll need is a gigabit card for the span port on the 3550 (or directly connected to the passive tap you've installed). ---Rico On Wed, 11 Aug 2004 16:37:24 +0200, Stefan Baltus <[EMAIL PROTECTED]> wrote: > > Hi, > > We have a situation where we need to intercept certain IP traffic > that is somewhere within a link of 300Mbit/s of traffic (GigabitEthernet). > The setup that we built is as follows: > > router > ^ > | GE > | > fiber tap -------> cisco catalyst 3550 > | > | GE > v > switch > > The catalyst 3350 is receiving the traffic from router to switch > and vice versa.
