Configuring NTP in client/server mode

Follow these guidelines when you configure an NTP client:

For the client to synchronize to an NTP server, make sure the server is synchronized by other devices or uses its local clock as a reference source.
If the stratum level of a server is higher than or equal to a client, the client will not synchronize to that server.
You can configure multiple servers by executing the ntp-service unicast-server or ntp-service ipv6 unicast-server commands multiple times.
When the device operates in client/server mode, specify the IP address for the server on the client.

To configure an NTP client:

Step	Command	Remarks
1. Enter system view.	system-view	N/A
2. Specify an NTP server for the device.	Specify an NTP server for the device:ntp-service unicast-server { server-name \| ip-address } [ vpn-instance vpn-instance-name ] [ authentication-keyid keyid \| priority \| source interface-type interface-number \| version number ] * Specify an IPv6 NTP server for the device:ntp-service ipv6 unicast-server { server-name \| ipv6-address } [ vpn-instance vpn-instance-name ] [ authentication-keyid keyid \| priority \| source interface-type interface-number ] *	By default, no NTP server is specified.
