SCPI Command Set

:SYSTem:COMMunicate:LAN:DNS

The set command will store the new LAN DNS server address(es) to be applied to the
WSA. This command does not take effect until

:SYSTem:COMMunicate:LAN:APPLy

is

sent (please refer to the Caution note of the :APPLy command). Once the setting is
applied, it is not affected by power-on,

, or

The query will return the LAN DNS address(es) set or that of the actual current
configuration if one is not issued. The CURRENT query will return what is currently and
actually used by the WSA's LAN interface.
