IPAM 4.9
The IPAM documentation is pretty lightweight, so I thought I turn to the community. There are two settings in IPAM called Neighbor Scanning. It is not clear what each do.
Doc: Neighbor scanning
1. Admin > IPAM Settings > Subnet Scan Settings > SNMP Scanning
Enable SNMP scanning (dependent on ICMP scanning)
Enable SNMP neighbor scanning What is neighbor scanning?
2. Manage Subnets & IP Addresses > Edit Subnet Properties > Neighbor Scanning (...What is neighbor scanning?)
Disable Neighbor Scanning
IP Address: 10.10.10.254
Scan Interval: 4 Hours

I thought that a device's MAC was contained in the switch it is connected to, and therefore, the router ARP would only have the MAC of the downstream switch, not the MAC of the end-point client device? So how can neighbor scanning provide any useful information unless you know what the upstream switch is for each subnet (and there are usually more than one switch, but IPAM only allows for one entry to do a Neighbor Scan)? This is a puzzler to me and I'd like to understand better.
