This section is only applicable to the lab application.
After the test set and the DUT have established a data connection, there goes PPP link establishment procedure. In the procedure, apart from the IP address assigned to the DUT, the DUT can also request the DNS addresses, either the Primary DNS Server address or the Secondary DNS Server address or both.
These DNS Server address settings are non-volatile (they persist across partial and full presets and power-cycling the test set).
You can set the Primary and Secondary DNS Server IP Address for the DUT. The GPIB command to set the Primary DNS Server IP Address is CALL:MS:DNSServer:PRIMary:IP:ADDRess . Then GPIB command to set the Secondary DNS Server IP Address is CALL:MS:DNSServer:SECondary:IP:ADDRess .
