I've been having a problem for about two months that I can't seem to get a resolution from TAC on so I thought I'd try here (SR 609853735).
DCR is not consistent in accurately discovering new devices on our network. I've run through our discovery config, debug logs etc. and it simply fails to discover new networks. It usually discovers new devices in a network it already knows about, but if we bring up a new site, it simply fails to add the devices and I in turn have to do it manually. Any suggestions?

From looking at your Discovery config, the most obvious problem is that you don't have seed devices in your new ranges. These new networks would have to be CDP reachable from your existing DCR devices, and it's not clear from the notes that that is the case.
If you can prove that a new device is CDP reachable from an existing DCR device, then I suggest you escalate your service request, so that more in-depth analysis can be done.
