I upgraded to IPAM 3.1.1, and now all my Cisco devices that are not in DNS, have had their manually entered host names have been overwritten/blanked out. I called support and after waiting for a half hour, I spoke with a technician that told me this is normal and this field has always been dynamic, use custom field for my host names. First off, It was not always like this, second, why would you be able to change a dynamic field if it is just going to be erased on the next scan?
I found this thread that was answered but it was with some file support sent the user. How would I get that file? http://thwack.solarwinds.com/message/146764#146764
