Neighbor Scanning in IPAM attempts to retrieve the status of a device that may not be responding to ICMP by scanning the ARP table of a neighbor router to see which IP addresses are active.

IPAM first checks if the device is capable of SNMP and supports ARP table:

To check whether SNMP is available, IPAM uses these OIDs:


To check whether the ARP table is available:


The IPNetToMediaTable is pulled for client information. If the device supports this table, then IPAM can work with it.

Under the OID IPAM will poll the following subsidary OIDs: ipNetToMediaIfIndex ipNetToMediaPhysAddress ipNetToMediaNetAddress ipNetToMediaType

A null return indicates the device does not support that MIB.
