Network Time Synchronization
To access the Network Time Synchronization fields:
1. Navigate to
System Configuration > Network > Network Time Synchronization section.
These fields are used to synchronize network time using the host name or IP address of a
known server to provide a synchronized time for all appliances in the network.
Search Domain These domains will be searched by your computer when
performing IP lookups for less than fully qualified or non-
canonical host names.
For example, if your Search Domain is “mycompany.com”
and you perform a ping on “testCompuerA”, then
“testComputerA.mycompany.com” will resolve (if possible)
and be pinged. Ping is used here just an example – any
application that needs name resolution will use this field for
domain search restriction.
Note: The Search Domain field is automatically supplied if
you have Network DHCP enabled. Any changes to these
addresses will be overwritten at boot up if DHCP is enabled.
Note: Network Administrators please note. DHCP Option 4 (TIME) and
Option 42 (NTP) are requested from the DHCP server to obtain SNTP
server addresses. One or both of these options must be enabled in the
DHCP server for these addresses to be returned to the DME. If both are
returned, the DME will use the NTP server address. If the DHCP server
configuration is unknown, it is recommended that the address(es) be
manually entered since the DHCP server-supplied address will always
override a manually-entered address.
Field Description
Network Time Protocol Check to enable network time synchronization. Default =
Disabled.
Primary Server IP Address Primary host name (DME Host Name or DNS Host Name)
or IP address of valid SNTP server providing time
synchronization. A blank field indicates the server address
will be acquired via the DHCP server only if the
Network
DHCP
field above is checked.
Secondary Server IP Address Secondary host name (DME Host Name or DNS Host
Name) or IP address of valid SNTP server providing time
synchronization. A blank field indicates the server address
will be acquired via the DHCP server only if the
Network
DHCP
field above is checked.
