Connected MAC Adresses

Hello,

I'm looking for a nice (and free) tool: I will create a complete list of all network devices and in this list I will add the informations: connected at cisco switch X. Yes it's easy to extracting a list of all connected MAC devices for each switch and yes it's also very easy for creating a list of all LAN contected MAC-adresses. But, but, but...

So it would be very nice of someone of you knows a proper "MAC reporting solution".

Thanks,

Bjoern

Re: Connected MAC Adresses

I think there are no free tools available. But I would like to inform that to find duplicate MAC addresses. Typically, each host has its own, unique MAC address. If two hosts have the same MAC address in the same VTP domain and VLAN, you have a misconfiguration.
