Set Up USRP E320 Radio for 10 Gigabit Ethernet

The USRP™ E320 radio has a single SFP port, SFP+, that supports 1 Gigabit Ethernet or 10 Gigabit Ethernet for streaming samples to the host computer. To set up your radio with a 10 Gigabit Ethernet connection, you must first set up your radio with a 1 Gigabit Ethernet connection using the Radio Setup wizard. You then manually load the XG variant of the FPGA image to enable 10 Gigabit Ethernet on the SFP+ port and use the Radio Setup wizard to modify and validate your radio setup configuration.

To set up a USRP E320 radio with a 10 Gigabit Ethernet connection, follow these steps:

  1. Use the Radio Setup wizard to set up your radio with a 1 Gigabit Ethernet connection.

    1. Use the radioSetupWizard function to open the wizard.

    2. Follow the steps to set up your radio with a 1 Gigabit Ethernet connection.

      Note

      • The 1 Gigabit Ethernet setup requires you to use an RJ45 cable with an SFP-to-RJ45 adapter to connect SFP+ to a 1 Gigabit network interface card (NIC) on the host.

      • If you do not have a 1 Gigabit NIC, or you have a single 1 Gigabit NIC that is required for internet access, you can use a USB3/Ethernet adapter dongle.

    3. Save a radio setup configuration and close the wizard.

  2. Use the sdruload function to load the XG variant of the FPGA image to your radio.

    sdruload(Device="e320", ...
  IPAddress="192.168.10.1", ...
  FPGAImage="E320_XG")

    When the FPGA image has loaded, you lose the connection to your radio. The operation times out and returns the following error:

    Error: Timeout loading bitstream to FPGA. Check network connections.

  3. Use the Radio Setup wizard to set up your radio with a 10 Gigabit Ethernet connection.

    1. Use the radioSetupWizard function to open the wizard.

    2. From the Manage Saved Radio Configurations dropdown, select the radio configuration you saved for your radio and click Modify.

    3. Skip the SD card setup, then follow the steps to set up your radio with a 10 Gigabit Ethernet connection.

      Note

      The 10 Gigabit Ethernet setup requires you to use an SFP cable to connect SFP+ to a 10 Gigabit NIC on the host.

    4. Save your radio setup configuration and close the wizard.

  4. Configure your host for 10 Gigabit Ethernet.

    1. Open Windows® Device Manager. Under Network adapters, identify the entry that corresponds to the NIC you are using for your Ethernet connection to the radio. Right-click the entry and click Properties in the context menu to open the Properties dialog box for your Ethernet adapter.

      In the Advanced tab, set the Jumbo Packet (or Jumbo Frame) value to one of the following options.

      • If the dialog box has a dropdown menu, select the largest value.

      • If you can enter a value, enter 9014, or the maximum supported value. The maximum size of an Ethernet jumbo frame, including the header, is 9014.

    2. Open a Windows command prompt or PowerShell as an administrator. Use network shell, netsh, to display details about your network interfaces.

      netsh interface ipv4 show subinterfaces
      Identify your Ethernet adapter from the list. If you set the jumbo packet value to 9014, set the MTU size to 9000. If you set the jumbo packet value to a different value, set the MTU size accordingly.
      netsh interface ipv4 set subinterface "<name of interface>" mtu=9000 store=persistent

You can now proceed to use your radio with Wireless Testbench™.
