I'm looking for a program (Windows or Linux) that can query a switch (specifically a Cat 6500 running hybrid) and tell me what IP (or even better, dns name) of machines connected to it. I do this currently with a combination of a few telnet session (one to the sup, and one to the msfc), sed and awk, and lots of copy-n-paste, but I'm pretty sure all this information is exposed via SNMP.
