Network Time Protocol (Ntp); Time - i3 International Cortex S243 User Manual

Network Time Protocol (NTP)

NTP is Network Time Protocol and is used to sync the network time based on Greenwich Mean Time (GMT). Select, the
NTP mode and select a built-in NTP time server or manually specify a user-defined NTP server as well as Time Zone. The
switch will sync the time after pressing the <Apply> button. Though it synchronizes the time automatically, NTP does not
update the time periodically without user's processing.
Time Zone is an offset time of GMT. You have to select the time zone first and then perform time sync via NTP because the
switch will combine this time zone offset and updated NTP time to determine the local time, otherwise, the correct time
will not be displayed. The switch supports configurable time zone from –12 to +13 step 1 hour. The default time zone is
GMT +8 Hrs).

Description
Indicates the NTP mode operation. Possible modes are:
Enabled: Enable NTP client mode operation.
Disabled: Disable NTP client mode operation.
Provide the NTP IPv4 or IPv6 address of this switch. IPv6 address is in 128-bit
represented as eight fields of up to four hexadecimal digits with a colon separating each
field (:). For example, 'fe80::215:c5ff:fe03:4dc7'. The symbol ':' is a special syntax that
can be used as a shorthand way of representing multiple 16-bit groups of contiguous zeros;
but it can only appear once. It can also represent a legally valid IPv4 address. For example,
'::192.0.0.10'.
