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. To configure an NTP client: Step 1. Enter system view. 2. Specify an NTP server for the device. Command system-view • Specify an NTP server for the device: ntp-service unicast-server { ip-address | server-name } [ 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 { ipv6-address | server-name } [ vpn-instance vpn-instance-name ] [ authentication-keyid keyid | priority | source interface-type interface-number ] * Remarks N/A By default, no NTP server is specified for the device. Configuring NTP in symmetric active/passive mode When the device operates in symmetric active/passive mode, specify on a symmetric-active peer the IP address for a symmetric-passive peer. Follow these guidelines when you configure a symmetric-active peer: • Execute the ntp-service enable command on a symmetric passive peer to enable NTP. Otherwise, the symmetric-passive peer will not process NTP messages from a symmetric-active peer. • Either the symmetric-active peer, or the symmetric-passive peer, or both of them must be in synchronized state. Otherwise, their time cannot be synchronized. • You can configure multiple symmetric-passive peers by repeating the ntp-service unicast-peer or ntp-service ipv6 unicast-peer command.

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.
To configure an NTP client:

the device:

By default, no NTP server is
specified for the device.
Configuring NTP in symmetric active/passive mode
When the device operates in symmetric active/passive mode, specify on a symmetric-active peer the IP
address for a symmetric-passive peer.
Follow these guidelines when you configure a symmetric-active peer:
•
Execute the
ntp-service enable
command on a symmetric passive peer to enable NTP. Otherwise,
the symmetric-passive peer will not process NTP messages from a symmetric-active peer.
•
Either the symmetric-active peer, or the symmetric-passive peer, or both of them must be in
synchronized state. Otherwise, their time cannot be synchronized.
•
You can configure multiple symmetric-passive peers by repeating the
ntp-service
unicast-peer
or
ntp-service
ipv6
unicast-peer
command.
