I noticed that a lot of my devices in CiscoWorks are duplicates. So I manually had to delete devices so I can only manage the IP for that particular device. How do we get cisco works to remove the dup's & look basically exactly as this list does now, even if Cisco works cannot manage the device?
This is a bug, CSCsm66330.
The Device Credential Repository contains duplicate devices are Common Services Discovery runs. A device may appear as both its hostname and one of its IP addresses in DCR.
This will occur if, for example, a device is manually added to DCR by an IP address, but CS Discovery determines that the device has a hostname which resolves to a different IP address. In that case, the previous DCR entry will remain, and a new one will be added for the new hostname and new IP address.
If devices are added to DCR using the same IP address and hostname that will be found when Discovery does its IP address to name resolution, then the duplication will not occur.
