ntp-service unicast-peer

ntp-service unicast-peer


The ntp-service unicast-peer command configures NTP peer mode.

The undo ntp-service unicast-peer command cancels the NTP peer mode.

By default, the NTP peer mode is not configured.

undo ntp-service unicast-peer ip-address


Parameter Description Value
ip-address Indicates the IPv4 address of the remote peer. The parameter ip-address is a host address and cannot be the broadcast address, the multicast address or the IP address of a reference clock.
version number Indicates the NTP version number. If this parameter is not specified, the default version number is used. Version number is an integer data type and ranges from 1 to 4. By default, it is 3.
authentication-keyid key-id Indicates the authentication key number used when transmitting messages to the remote peer. If this parameter is not specified, authentication is not performed.

Key ID is an integer and ranges from 1 to 4294967295.

maxpoll max-number

Indicates the maximum NTP poll interval.

The value is an integer that ranges from 10 to 17.

minpoll min-number

Indicates the minimum NTP poll interval.

The value is an integer that ranges from 3 to 6.

source-interface interface-type interface-number Indicates the source interface from which the symmetric active end sends NTP packets to the symmetric passive end. The source IP address of the NTP packets is the IP address of this interface. -
preference Indicates the remote peer as the preferred one. By default, the remote peer is not preferred. -

Usage Guidelines

Usage Scenario

When the clock of a device on the network needs to be synchronized in symmetric peer mode, you can run the ntp-service unicast-peer command to configure a remote node as the symmetric peer of the device. The local device runs in symmetric active peer mode. In this mode, the device and the remote peer can be synchronized with each other.


# Configure the peer to provide the synchronizing time for the local device. The local device can also provide synchronizing time for the peer. The version number is 3. The IP address of the NTP packets is the address of VLANIF100.
