to configure NTP server.
Figure 3-3: The NTP Configuration page
NTP (Network Time Protocol) is used to sync the network time based Greenwich Mean Time (GMT). If
use the NTP mode and select a built-in NTP time server or manually specify an user-defined NTP server
as well as Time Zone, the switch will sync the time in a short after pressing 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 off 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 come out the
local time, otherwise, you will not able to get the correct time. The switch supports configurable time
zone from –12 to +13 step 1 hour. The default Time zone is +8 Hrs.
Parameter descriptions:
Server 1 to 6: Provide the NTP IPv4 or IPv6 address of this switch. IPv6 address is in 128-bit records
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 '::' 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 valid
IPv4 address. For example, '::192.1.2.34'.
Interval: You can specify the time interval in seconds after which a time check and, in case of deviation,
a resynchronization of the internal device clock against the specified timeserver via Network Time
Protocol (NTP) should be performed. The valid range is 10-2880 minutes. The default is 1440 minutes.
