find out ip address for each port in switch

let say i have a cisco switch 100 Mbps 24 port...
each port has a cable that connect to pc (user)

what i want to know is the ip address of computer through the switch port....is that possible....

any techniques or tools that i can use....

i heard about fluke before...but it quite expensive ...and i prefer to something that doesn't need to pay ....in the other words, free of charge...

anyone here???

Try Ettercap. Use a simple arp broadcast to find out the IPs. :D

Thread moved to GCC since this really isn't a security question.

I have a 24 port switch, on my netowrk, and If I need to find out IP's something as simple as Ms.Mittens suggestion works wonder, or if you want vulnerabilities along with IP's, I use Languard from GFI soft.
