This is a great alternative to monitor the Layer 3 info in User Device Tracker.
Let's go!
Things needed:
-Windows DHCP Server with SNMP service enabled.
-Orion Web Console.
-Install the SNMP service and WMI provider features on the target windows server.
-Go into the properties of the SNMP service and add a read-only community string. (The host restriction is very important because Windows only supports SNMPv2c)
-Add the Windows DHCP server as a node using SNMP polling method.
-Select Layer 3 polling under the add node page.
-Submit.
The MAC-to-ARP-to-DNS entries on my switch ports updated fairly quickly after this. Tested this and confirmed working on Windows Server 2016 and Windows Server 2012.
Important Note:
SNMP on Windows is officially a deprecated feature, though. So it may stop working in the future.
This will poll data off a DHCP server, so any non-DHCP clients may or may not show up.
Tip:
Creating a script on the Windows host to ping every other host on the subnet periodically to keep the ARP table up-to-date as well.
