RE: Tracking back internal incidents to users, not IPs

then queries your DHCP server(s) for active leases with MAC adresses,

compares the MAC address to the switch's MAC table, then queries your
database/spreadsheet for jack number to switch port assignments and
updates the user object via an LDAP modify command.  


Have a look at Netdisco (netdisco.org). It does an SNMP walk and dumps
the switch ARP/IP tables into a database which you can query using
CGI+Apache. I used it in a 10K host network and it helped me a lot.
Using Netdisco you can track down a MAC to a port and shut down the port
in a couple of seconds. 

Thanks,
Mike
