LLDP is the only source of physical switch/port topology in the estate; NetBox has no other way to learn which switch and port each machine is cabled to. Run lldpd on physical hosts and surface its neighbour data so the terraform-infra pdbmux backfill can populate NetBox interface connections. - add profiles::lldpd installing the lldpd package and enabling+starting the service (it ships disabled), the service subscribing to the package - assign it physicals-only via hiera_include in hieradata/virtual/physical.yaml (facts.virtual == 'physical'), merged unique with the common hiera_include; VMs never get it - add the `lldp` custom fact (modules/libs/lib/facter/lldp.rb) parsing `lldpctl -f json0` into a per-interface map of neighbour chassis/port/vlan, skipping interfaces with no neighbour; confined to physical Linux hosts with lldpctl and a live lldpd socket, and never raising (empty hash on any error) Claude-Session: https://claude.ai/code/session_01JUoARVdmhxKQHyyyp1pxeT
