54.2.8 NTP and Daylight Saving Time Parameters
The Network Time Protocol (NTP) and daylight saving time parameters are described in
the table below.
Table 54-16: NTP and Daylight Saving Time Parameters
Parameter Description
NTP Parameters
Note: For more information on Network Time Protocol (NTP), see ''Simple Network Time Protocol
Support'' on page 103 .
Web: NTP Server Address
EMS: Server IP Address
CLI: primary-server
[NTPServerIP]
Defines the IP address (in dotted-decimal notation or as an FQDN)
of the NTP server. The advantage of using an FQDN is that multiple
IP addresses can be resolved from the DNS server, providing NTP
server redundancy.
The default IP address is 0.0.0.0 (i.e., internal NTP client is
disabled).
Web: NTP Secondary Server
Address
[NTPSecondaryServerIP]
Defines a second NTP server's address as an FQDN or an IP
address (in dotted-decimal notation). This NTP is used for
redundancy; if the primary NTP server fails, then this NTP server is
used.
The default IP address is 0.0.0.0.
Web: NTP UTC Offset
EMS: UTC Offset
CLI: utc-offset
[NTPServerUTCOffset]
Defines the Universal Time Coordinate (UTC) offset (in seconds)
from the NTP server.
The default offset is 0. The offset range is -43200 to 43200.
Note: The offset setting is applied only on the hour. For example, if
you configure this parameter at 15:42, the device applies the setting
only at 16:00.
Web: NTP Update Interval
EMS: Update Interval
CLI: update-interval
[NTPUpdateInterval]
Defines the time interval (in seconds) that the NTP client requests
for a time update.
The default interval is 86400 (i.e., 24 hours). The range is 0 to
214783647.
Note: It is not recommend to set this parameter to beyond one
month (i.e., 2592000 seconds).
Web: NTP Authentication Key
Identifier
CLI: configure system > ntp >
auth-key-id
[NtpAuthKeyId]
Defines the NTP authentication key identifier for authenticating NTP
messages. The identifier must match the value configured on the
NTP server. The NTP server may have several keys configured for
different clients; this number identifies which key is used.
The valid value is 1 to 65535. The default is 0 (i.e., no authentication
is done).
Web: NTP Authentication
Secret Key
CLI: configure system > ntp >
auth-key-md5
[ntpAuthMd5Key]
Defines the secret authentication key shared between the device
(client) and the NTP server, for authenticating NTP messages.
The valid value is a string of up to 32 characters. By default, no key
is defined.
Daylight Saving Time Parameters
Web: Day Light Saving Time
EMS: Mode
CLI: summer-time
[DayLightSavingTimeEnable]
Enables daylight saving time.

[0] Disable (default)

[1] Enable
Web: Start Time / Day of Defines the date and time when daylight saving begins. This value
