button: Click to configure NTP
server(s) when Clock Source is “NTP Server”.
Figure 2-3: NTP Configuration
NTP ( Network Time Protocol) is used to sync the network time based Greenwich Mean Time (GMT). If you use
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 in a short while after clicking the Apply button. Though it synchronizes the
time automatically, NTP does not update the time periodically without user action.
Time Zone is an offset time of GMT. You must select the time zone first and then perform a time sync via NTP
because the switch will combine this time zone offset and updated NTP time to come up with the local time.
Otherwise, you will not be able to get the correct time. The switch supports a configurable time zone from –12
to +13 in 1 hour steps. The default Time zone is +8 Hrs.
Parameter descriptions
:
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, with the entry
'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. It can only appear once., and it can also represent a valid IPv4
address (e.g., '::192.1.2.34').
