Configuring NTP association mode
This section describes how to configure NTP association modes.
Configuring NTP in client/server mode
When the device operates in client/server mode, specify the IP address for the server on the client.
Follow these guidelines when you configure an NTP client:
• A server must be synchronized by other devices or use its local clock as a reference source
before synchronizing an NTP client. Otherwise, the client will not be synchronized to the NTP
server.
• 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 repeating the ntp-service unicast-server and
ntp-service ipv6 unicast-server commands.

the device.
• Specify an NTP server for
the device:
ntp-service unicast-server
{ server-name | ip-address }
[ 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 }
[ authentication-keyid
keyid | priority | source
By default, no NTP server is
specified for the device.
