5.13. Creating a Network Team Using a GUI

5.13.1. Establishing a Team Connection

You can use the GNOME control-center utility to direct NetworkManager to create a team from two or more Wired or InfiniBand connections. It is not necessary to create the connections to be teamed first. They can be configured as part of the process to configure the team. You must have the MAC addresses of the interfaces available in order to complete the configuration process.

  1. Press the Super key to enter the Activities Overview, type control network and then press Enter. The Network settings tool appears. This step is fully covered in Section 2.3, “Using NetworkManager with the GNOME Graphical User Interface”.
  2. Select Team. The Editing Team Connection 1 window appears.

    • Automatically connect to this network when it is available — Select this box if you want NetworkManager to auto-connect to this connection when it is available. See Section 2.3.3, “Connecting to a Network Automatically” for more information.
    • All users may connect to this network — Select this box to create a connection available to all users on the system. Changing this setting may require root privileges. See Section 2.3.5, “System-wide and Private Connection Profiles” for details.
    • Automatically connect to VPN when using this connection — Select this box if you want NetworkManager to auto-connect to a VPN connection when it is available. Select the VPN from the drop-down menu.

If the profile is OFF, set it to ON or select it in the network connection icon's menu. See Section 2.3.1, “Connecting to a Network Using a GUI” for information on using your new or altered connection.
You can further configure an existing connection by selecting it in the Network window and clicking Options to return to the Editing dialog.
