The Secondary DNS Server Address is checked when the Set button is pressed to download data to the module. If any of the disallowed values are entered and you attempt to download, this error is displayed and no values are downloaded to the module.
Enter the correct Secondary DNS Server Address or contact your network administrator for the correct Secondary DNS Server Address.
