Thanks, Christian. You were right. So, applying an LLDP profile permitting the
needed TLVS and a management address has the palo sending the required
information to the switches.
The problem I'm facing now is inconsistency; whenever a discover all is run,
something different is reported. The firewall has four switches hanging from
it. I can't consistently get ND to report them as neighbors; I get random
combinations.
Is anyone familiar with this behavior? Is there anything I can do to make
things more predictable?

Yes most likely the Addresses not advertised are the issue, Netdisco
will use this to form the neighbor relation.
