There seems to be some sort of bug that happens since hitting late 1.2.x releases. The PNP templates have to either be saved/confirmed or lately recreated all together. If not PNP can't find or use the templates…

Another bug that has hit multiple times is a log file filling up entire disk on a node in the cluster.

Cisco recommends vlan 1 PNP max of 2 hops hitting dhcp with option 43 for dnac server. Tested 4 away and it still seems to be fine.
