In Campus manager, I am seeing a few devices that are not in the same format as the DCR.
In DCR the device list is organized per the ACS devices.
The collections look ok (I was able to get the missing items in the list by editing the collection filter per your suggestion), but I am still seeing the switches in the list by an IP Address not configured anywhere.
Like remnants of past problems maybe?
I deleted one of the switches from DCR and it still shows up in the Campus manager with the IP Address as the device name (should be hostname per DCR)
