This is pretty unusual. FindIT and the 200 series switches have been well tested to ensure interoperability. Can you provide a few more details? In particular, the version firmware running on the switch, the version of FindIT that you are running, the IP address of your PC, and a screenshot of the FindIT balloon showing the switch details?
Can you please verify if there is an entry for the switch name in your DNS server? If it is a local network, is there a WINS server that keeps track of the local names? Can you edit the "hosts" file on the PC and add an entry for the switch name and see if the name gets resolved?
Ok, assuming you are able to connect to other device correctly using FindIT, this does tend to indicate a problem with the switch. We release the 220.127.116.11 firmware update for these switches a couple of weeks ago, so it would be worth upgrading the firmware on the switch and see if the problem gets addressed. I'm not aware of any specific bugfixes in that release that would address this, but I haven't been through the full list of fixes to confirm.
In the meantime, I'll have a talk to engineering and see if they have seen this before.
Can you attach the sniffer trace? Or alternatively email it to me at firstname.lastname@example.org. Our QA folks retested this yesterday and there were no obvious problems. But I would like to go through the trace in detail to see exactly what is happening.
