It is becoming commonplace to have more than one Ethernet adapter in a PC or embedded controller, especially in systems where wired and wireless adapters are both present. However, the presence of more than one Network Interface Card (NIC) can cause connectivity problems if each network interface is not carefully configured to account for the overall network layout. This tutorial outlines basic Ethernet networking concepts, explains why incorporating multiple NICs can cause problems, and provides best practices to follow when working with a multi-NIC system. In addition, several common scenarios are explored, including an NI Real-Time Hypervisor system that features a complex network configuration. Before explaining best practices for configuring controllers with multiple NICs, it is necessary to understand some basic concepts related to Ethernet networking. This section explains how individual NICs are addressed, how packets are routed on Ethernet networks, and what a typical Ethernet packet transfer looks like. If you are already familiar with these concepts or are not concerned about the "why" behind the recommendations in this paper, then you can skip to the Guidelines for Configuring Multi-NIC Systems section. Data Link Layer: MAC Addressing Just like a home or business address must be specified in order to send a piece of postal mail, every port on every Ethernet adapter is assigned a unique address called a Medium Access Control (MAC) address by the manufacturer.

In this article Applies to: Windows Server 2022, Windows Server 2019, Azure Stack HCI, versions 21H2 and 20H2 You can manage NICs and all the features via Windows PowerShell using the • In Windows PowerShell, run the Get‑NetAdapterAdvancedProperty cmdlet against two different make/model of NICs. There are similarities and differences in these two NIC Advanced Properties Lists. • In the Network Control Panel (ncpa.cpl), do the following: a. Right-click the NIC. b. In the properties dialog, click Configure. c. Click the Advanced tab to view the advanced properties. The items in this list correlates to the items in the Get-NetAdapterAdvancedProperties output.
