The IPv6 function must be enabled for the IPv6 DNS function. The IPv6 function is controlled by a license. By default, the IPv6 function is disabled on a new device. To use the IPv6 function, apply for and purchase the license from the device supplier.

For details about how to apply for a license, see Obtaining Licenses in the S7700 and S9700 Series Switches License Usage Guide.
