NAV v5.0.5 appears to have a problem in the topology/LLDP portion. The switch referenced below is a Cisco WS-3750X stack, running 15.2(4)E10. Referenced devices are [Ubiquiti] APs. FWIW – the switch does have such things as ARP inspection, DHCP snooping, etc. – enabled.

Related: Was running an older version of NAV which appeared (at least via GUI) to have no issue this equipment combination of Cisco and Ubiquiti. Due to an odd issue, did end up dropping the VM and simply created a new one with latest Debian and latest NAV version, re-populating the equipment and configuration. Which may have been why certain things came to light? The Netmap doesn’t appear to be fully populated – suspect that it’s a cascading result of the above error?
