I'm trying to figure out which computers (IP addresses) are plugged in to which ports on my Procurve 2650 Switch. I'd rather not have to trace the physical wires all the way back to the actual computer. Is there anything that could tell me which clients are going into which ports?
 
If you're running Procurve Manager and are collecting Sampler data from all switches there is a way...

In PM, goto Traffic Monitor. Near the bottom of the page you'll see 'Selected Segment' and a drop-down listing every switch and port that PM knows about. Select the switch and port you're interested in and click Show Details.

This will pop up a window; from the 'View' menu select 'Utilization %' then select the Connections tab. Click on one of the bars in the chart and it will tell you what IP the traffic sourced from and is headed to.

Clunky, but it beats manually tracing wires. I've tried several 'port finder' gizmos that worked fine on hubs but don't work on my 2524 switches.

 
When I need to do this without any whizbang tools, I just ping the IP address of the client, dump the ARP cache to find it's MAC address, and then look at the address table in the switch to figure out what port it's on.
