Figure 2-3: The SNTP configuration
NTP is Network Time Protocol and 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 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 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.
Default Time zone: +8 Hrs.
Parameter description :

Server 1 to 5 :
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 '::' 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,
'::192.1.2.34'.
