SYSTem:COMMunicate:LAN:SMASk "<mask>"
SYSTem:COMMunicate:LAN:SMASk? [{CURRent|STATic}]]
Assigns a subnet mask for the instrument to use in determining whether a client IP address is on the same
local subnet. When a client IP address is on a different subnet, all packets must be sent to the Default Gate-
way. Contact your LAN administrator for details.
If you change this setting, you must send SYSTem:COMMunicate:LAN:UPDate to activ-
ate the new setting.
Parameter Typical Return
Command: "nnn.nnn.nnn.nnn". Default: "255.255.0.0".
Query: {CURRent|STATic}. Default: CURRent.
"255.255.255.0"
Set the subnet mask:
SYST:COMM:LAN:SMAS "255.255.255.0"
SYST:COMM:LAN:UPD
l On the 34460A, this requires option 34460A-LAN or option 3446LANU.
l If DHCP is enabled (SYSTem:COMMunicate:LAN:DHCP ON), the specified subnet mask is not used.
However, if the DHCP server fails to assign a valid IP address, the instrument uses the Auto-IP subnet
mask.
l A value of "0.0.0.0" or "255.255.255.255" indicates that subnetting is not being used.
l SYSTem:SECurity:IMMediate sets this parameter to its default value.
l
CURRent: returns address currently being used by the instrument.
l
STATic: returns static address from non-volatile memory. This address is used if DHCP is disabled or
unavailable.
l This setting is non-volatile; it is not changed by power cycling, a Factory Reset (*RST), or an Instru-
ment Preset (SYSTem:PRESet).
