Netdisco LLDP discovery

This is kind of a longshot...
I use netdisco to keep track of layer 2 topology, and most of its data comes from lldp, which it accesses via SNMP downloading the results of lldp discovery of neighbors.
lldp is available for OPNsense (and I'm running it). OPNsense sees its neighbors.
Netdisco does not see neighbors, or connected devices, and I think it is because the snmp implementation is not providing data on macs on ports, neighbors from lldp, etc. Emphasis on "think", a brief look through snmpwalk didn't see that kind of data.
Anyone been down this path - is this a restriction in the snmp implementation? Some mibs not turned on (and can they be)? Something in netdisco?
It's a minor nit -- OPNsense is not connected to much as it is on the edge. But I was hoping for consistency.
