Im trying to find a command that will return the ip addresses of all machines connected to my switch in my building. I dont want to have to physically run from the port all the way to each individual computer. I want to know which computer with what IP address is connectedd to what port. Im trying to add anohter computer to my network and Im pretty sure not all of them are connected and being used.

Can you look at Ip's and PC names in the DHCP Scope?

3Com's have a port database in the web interface, and telnet interface.

Cisco products have the Network assistant that you can browse into them with.

Those are the only switches I have familiarity with, but most have a web interface.

Like shasca said, to query the switch is switch specific, and your switch may or may not have the functionality for you to query its ARP tables. You can post back your switch make/model and someone can tell you. The cheapie SOHO non-managed switches will not have this functionality.

Another option is this freebie but goodie, "The Dude" network monitoring software.

It will scan your network and report back everything it finds. Pretty good tool, though it will not tell you which switchport something is plugged into.
