On the other hand, there is a mac address to ip address mapping in snmp mib variables (as long as your switch supports it). Without looking it up, it might be something like PhysAddrToInetAddr. ....

Nope, wait, after just looking it up, ip.ipNetToMediaTable.ipNetToMediaEntry.* is what you want.

snmpwalk <switchname> <communityname> IpNetToMediaEntry

Will list all (I believe) ports, which ip address is on that port, and which mac address is associated with that ip address.

That could help, I guess.
