2. Click Add (displays dialog).
3. Enter Name.
4. On Type drop-down, select Ethernet (dialog changes).

10. In the Ethernet Connection menu, on the Link Mode drop-down (availability depends on the interface and the device model), enable the Auto selection or select the forced or advertised speed/duplex (options vary depending upon the hardware and SFP transceiver used). You can navigate to the path Tracking:: Network:: Interface or execute the command "ethtool <interface>" from the shell access to view the configured speed/duplex.
11. On the Enable IP Passthrough checkbox (expands dialog) enter the details:
    1. Ethernet Connection drop-down, select one (selection varies depending on device)
