Parameters
server-name: Specifies an NTP server by its host name, a case-insensitive string of 1 to 253
characters.
ip-address: Specifies an NTP server by its IP address. It must be a unicast address, rather than a
broadcast address, a multicast address, or the IP address of the local clock.
authentication-keyid keyid: Specifies the key ID to be used for sending NTP messages to the NTP
server. The value range for the keyid argument is 1 to 4294967295. If you do not specify this option,
the local device and NTP server do not authenticate each other.
priority: Specifies this NTP server as the first choice under the same condition.
source interface-type interface-number: Specifies the source interface for NTP messages. For an
NTP message the local device sends to the NTP server, the source IP address is the primary IP
address of this interface. The interface-type interface-number argument represents the interface
type and number. If you do not specify this option, the device searches the routing table for the
outgoing interface and uses the primary IP address of the outgoing interface as the source IP
address of the NTP messages.
version number: Specifies the NTP version. The value range for the number argument is 1 to 4. The
default value is 4.
Usage guidelines
When you specify an NTP server for the device, the device is synchronized to the NTP server, but the
NTP server is not synchronized to the device.
Examples
# Specify NTP server 10.1.1.1 for the device, and configure the device to run NTP version 4.
<Sysname> system-view
[Sysname] ntp-service unicast-server 10.1.1.1 version 4
