Try SNMP tools and 'switch port mapper' by Solarwinds Engineer's edition

I was doing the same thing this week, enumerating targets from a large Class B internal network during a pen test

Hello all,

I'm looking for a tool that can query a list of managed switches (both
Foundry and Cisco) via SNMP and return ports on those switches that
have more than one end host connected (based on MAC addresses).  It
would need to filter out ports that are connected to other managed
switches in the list as well as ports that are setup as trunk links.

I know that there may be some configuration/modification involved in
whatever tool I find, I'm just looking for something that keeps me
from coding it from the ground up.

Any ideas?

Thanks,
Matt
