Hello Tyla34,
thank you for your KB-post.
That's the actual NIC's that your operating system (the target device) reports. That's very common actually, for instance, this is the list of interfaces available on a system with 1 physical NIC and a Hyper-V switch (Required when using Hyper-V):
| 1.3.6.1.2.1.2.2.1.2.1 | "Software Loopback Interface 1 |
| 1.3.6.1.2.1.2.2.1.2.2 | "Hyper-V Virtual Switch Extension Adapter |
| 1.3.6.1.2.1.2.2.1.2.3 | "Hyper-V Virtual Ethernet Adapter |
| 1.3.6.1.2.1.2.2.1.2.4 | "Microsoft ISATAP Adapter |
| 1.3.6.1.2.1.2.2.1.2.5 | "Microsoft ISATAP Adapter #2 |
| 1.3.6.1.2.1.2.2.1.2.6 | "Intel(R) Ethernet Connection (2) I219-LM |
| 1.3.6.1.2.1.2.2.1.2.7 | "Microsoft Kernel Debug Network Adapter |
| 1.3.6.1.2.1.2.2.1.2.8 | "Hyper-V Virtual Switch Extension Adapter-Hyper-V Virtual Switch Extension Filter-0000 |
| 1.3.6.1.2.1.2.2.1.2.9 | "Hyper-V Virtual Ethernet Adapter-WFP Native MAC Layer LightWeight Filter-0000 |
| 1.3.6.1.2.1.2.2.1.2.10 | "Hyper-V Virtual Ethernet Adapter-QoS Packet Scheduler-0000 |
| 1.3.6.1.2.1.2.2.1.2.11 | "Hyper-V Virtual Ethernet Adapter-WFP 802.3 MAC Layer LightWeight Filter-0000 |
| 1.3.6.1.2.1.2.2.1.2.12 | "Intel(R) Ethernet Connection (2) I219-LM-WFP Native MAC Layer LightWeight Filter-0000 |
Every device will have at least one Loopback interface plus the actual Interface/NIC. But some operating systems (In this case) will generate several "hidden" auxiliary interfaces. The operating system's documentation will most likely tell you what these are.
You can usually manually "pick/identify" the relevant adapters, in this case:
| 1.3.6.1.2.1.2.2.1.2.6 | "Intel(R) Ethernet Connection (2) I219-LM |
| 1.3.6.1.2.1.2.2.1.2.3 | "Hyper-V Virtual Ethernet Adapter |
This name will match the "Device Name" displayed on the Operating System under "Network Connections". When using the Auto-Discovery PRTG avoids "non-relevant" interfaces by only adding interfaces which have traffic counters (IN/OUT) above 0. But in some cases these interfaces will also have accounted for traffic and will be added by auto-discovery. The other interfaces can be safely deleted/removed from monitoring.
