74.2.7 NTP and Daylight Saving Time Parameters
The Network Time Protocol (NTP) and daylight saving time parameters are described in
the table below.
Table 74-16: NTP and Daylight Saving Time Parameters
Parameter Description
NTP Parameters
CLI path: configure system > ntp >
Note: For more information on Network Time Protocol (NTP), see Simple Network Time Protocol
Support on page 133.
Primary NTP Server
Address
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).
Secondary NTP Server
Address
secondary-server
[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.
NTP Update Interval
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 the parameter to beyond one month
(i.e., 2592000 seconds).
NTP Authentication Key
Identifier
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).
NTP Authentication
Secret Key
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.
Regional Clock and Daylight Saving Time Parameters
UTC Offset
configure system > clock
> utc-offset
[NTPServerUTCOffset]
Defines the Universal Time Coordinate (UTC) offset (in seconds) from
the local time.
The valid range is -43200 to 43200. The default is 0.
Note: The offset setting is applied only on the hour. For example, if you
configure the parameter at 15:42, the device applies the setting only at
16:00.
Daylight Saving Time
configure system > clock
> summer-time >
summer-time
[DayLightSavingTimeEna
ble]
Enables daylight saving time (DST).

[0] Disable (default)

[1] Enable
