4.2.1.6 NTP Configuration
Configure NTP on this page. NTP is an acronym for Network Time Protocol, a network protocol for synchronizing the clocks of
computer systems. NTP uses UDP (data grams) as transport layer. You can specify NTP Servers. The NTP Configuration
screen in Figure 4-2-1-8 appears.
Figure 4-2-1-8: NTP
Configuration Page Screenshot
The page includes the following fields:
Object Description
• Mode
Indicates the NTP mode operation. Possible modes are:
Enabled: Enable NTP mode operation. When enabling NTP mode
operation, the agent forward and transfer NTP messages between the
clients and the server when they are not on the same subnet domain.
Disabled: Disable NTP mode operation.
• Server #
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 also uses a legal IPv4 address
like '::192.1.2.34'.
