Specifying an NTP server for the device

Step	Command	Remarks
1. Enter system view.	system-view	N/A
2. Specify an NTP server for the device.	For IPv4:sntp unicast-server { server-name \| ip-address } [ vpn-instance vpn-instance-name ] [ authentication-keyid keyid \| source interface-type interface-number \| version number ] * For IPv6:sntp ipv6 unicast-server { server-name \| ipv6-address } [ vpn-instance vpn-instance-name ] [ authentication-keyid keyid \| source interface-type interface-number ] *	By default, no NTP server is specified for the device. Repeat this step to specify multiple NTP servers. To use authentication, you must specify the authentication-keyid keyid option.

2. Specify an NTP server for the device.

For IPv4:sntp unicast-server { server-name | ip-address } [ vpn-instance vpn-instance-name ] [ authentication-keyid keyid | source interface-type interface-number | version number ] *
For IPv6:sntp ipv6 unicast-server { server-name | ipv6-address } [ vpn-instance vpn-instance-name ] [ authentication-keyid keyid | source interface-type interface-number ] *

By default, no NTP server is specified for the device.

Repeat this step to specify multiple NTP servers.

To use authentication, you must specify the authentication-keyid keyid option.

To use an NTP server as the time source, make sure its clock has been synchronized. If the stratum level of the NTP server is greater than or equal to that of the client, the client does not synchronize with the NTP server.
