ipconfig To view clock’s current IP settings:

ipconfig -o xxx Use DHCP to lease an IP address and request a configuration string where xxx is the private option number. Factory default is 230.

ipconfig -o -  will disable the configuration portion of the DHCP process.

ipconfig -dUse DCHP to lease an IP address and retrieve network settings.:

ipconfig -axxx.xxx.xxx.xxx -myyy.yyy.yyy.yyy -gzzz.zzz.zzz.zzz

where xxx.xxx.xxx.xxx is the IP address, yyy.yyy.yyy.yyy is the subnet mask, and

zzz.zzz.zzz.zzzis the gateway address. (All the information is ignored if DHCP is enabled.) - To configure a static IP address:

ipconfig -hhostname where hostname is the new hostname. - To change the hostname of the clock.

sntp To view the current time server and other SNTP settings:

sntp -hxxx.xxx.xxx.xxx where xxx.xxx.xxx.xxx is the hostname or IP address of the desired time server. - To change the time server the clock synchs with.

sntp -sTo trigger an immediate SNTP time synchronization.

timezone To view the clock’s current time zone setting.

timezone –N or timezone N To change the clock’s time zone setting, (don’t use a + sign for positive values) where N = the desired time zone offset in the range -11 to 12.

For example, to set the time zone for (GMT -5) Eastern Time (US & Canada), you would use: timezone -5

Note: If you’re not sure what time zone offset to use, check the time zone value used on a Windows PC on your network; double-click on the time in the Windows service tray (in the lower-right corner of your screen) and choose the Time Zone tab.

sntp –hhostname where hostname is the hostname of the time server.

sntp -s

dhcpconfig Lists the option settings received from a DHCP server (for verification purposes only).
