  3. View network interface configurations.
  4. Alternatively
  5. What is my IP address?
  6. The redundant network card that needs to be disabled is typically identified by a name starting with ethX or ensX.
  7. Disable the network card using the following command (replace ethX with the name of the network card to be disabled):
  8. Disable the ethX interface using the sudo command.
  9. Or alternatively
  10. Disable network interface ethX.
  11. Use the following command again to check the network interface and make sure the network card has been disabled:
  12. Display network interface configuration.
  13. Or perhaps
  14. internet protocol address
