Enabling or disabling IPv6

You can enable IPv6 on all the interfaces of your storage system either during setup or when the storage system is in operation. You can also disable IPv6 on your storage system if you want to revert to IPv4 addressing. You can enable IPv6 only for the entire storage system, but not for a network interface or vFiler unit.

Considerations

You have the option to enable IPv6 during initial system configuration when the setup command is run for the first time. If you want to enable IPv6 later, you can rerun the setup command or configure IPv6 manually. For more information about the setup command, see the Data ONTAP Software Setup Guide.

Step

To enable or disable IPv6 when the storage system is in operation (not during setup), enter the following command: options ip.v6.enable {on|off}
on—Enables IPv6

off—Disables IPv6

After You Finish

If you have enabled IPv6 when the storage system is in operation, you need to manually restart all server applications, except CIFS, FTP, and HTTP, to run over IPv6. For CIFS, FTP, and HTTP to work over IPv6, you must enable their individual IPv6 options. For more information about the protocols supported over IPv6, see the Data ONTAP File Access and Protocols Management Guide.

Note: If the applications are running only over IPv4, you do not need to restart the applications.
