Hi

With Ciscoworks Campus Manager you can easily find any MAC connected to your network. But you need to buy the LMS suite, and it's not for free :-)

An other way is to use a Layer 2 trace, but all devices in between have to support that feature, don't ask me which platforms/software releases, do it or not.

Thanks you Simon,

I know the cost of the Cisco management tool. It's the reasonsI'll do it manually ;-)

You speak about : Layer 2 trace . What does you mean ? Have you any example ?
