I searched and from what I am gathering so far, IPAM uses SNMP to gather MAC addresses? Is this correct?
I noticed i only have mac addresses for devices that are also nodes in Orion. I found this when looking to see why IPAM did not detect a duplicate IP between two devices.
Is this something that neighbor scanning would most likely resolve? Reading the documentation, it indicates that neighbor scanning is only used when icmp fails. These are devices that do respond to ICMP, but not SNMP.
