I did get some varied results using netdisco against a cisco network
recently that went as far back as 2900/3500xl up to c9410's with no
connected devices that weren't cdp. A lot of devices didn't register on
newer xe devices, 4k's had ios-xe / 03.07.03.E and the 9400's 16.9.3. The
graveyard 2k/3k/6k-era stuff on !xe collected just fine.
Probably cisco changing/making new mibs, ie. randomly breaking other things
(like ND) as usual. I never did get around to debugging it much, but node
detail would have been nice. Figure its time for a new upgraded nd2
appliance, but perhaps deeper issues if yours *is* a newer version. Mine
is a few years old at least, but has served me well in a pinch over the
years.

I have seen this behavior on multiple Cisco switches if LLDP is not
running. In my instances, enabling LLDP, and re-running macsucks fixed it.
