authentication-keyid keyid: Specifies the key ID to be used for sending NTP messages to the NTP
server, where keyid is in the range of 1 to 4294967295. If the option is not specified, 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.
version number: Specifies the NTP version. The value range for the number argument is 1 to 4, and
the default 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.
To synchronize the PE to a PE or CE in a VPN, provide vpn-instance vpn-instance-name in your
command.
If you include the vpn-instance vpn-instance-name option in the undo ntp-service unicast-server
command, the command removes the NTP server with the IP address of ip-address in the specified
VPN. If you do not include the vpn-instance vpn-instance-name option in the command, the
command removes the NTP server with the IP address of ip-address in the public network.
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
