Yeah...... in the switch, get the MACs of all of the devices attached to that port, then go to the router that acts as the gateway for that subnet that those devices are in, and do a 'show arp' then (hopefull you have a good terminal program to) search through and find the IPs that go with the MACs.....
I don't quite know what you're saying about "have your host ping all known IPs so it's ARPs them...".... If you're not on the same IP subnet, all your ARP is going to get you is the MAC of your gateway router, and either way, unless you're on the same switch with the target devices, pinging or ARPing or whatever isn't going to pull the target MACs into the CAM on your switch....
