In an NTP message the local device sends to its peer, the source IP address is the primary IP address of this interface. The interface-type interface-number argument represents the interface type and number. version number: Specifies the NTP version, where number is in the range of 1 to 4. The default value is 4. Usage guidelines When you specify a passive peer for the device, the device and its passive peer can be synchronized to each other. If their clocks are in synchronized state, the clock with a high stratum level is synchronized to the clock with a lower stratum level. To synchronize the PE to a PE or CE in a VPN, provide vpn-instance vpn-instance-name in your command. If you include vpn-instance vpn-instance-name in the undo ntp-service unicast-peer command, the command removes the symmetric-passive peer with the IP address of ip-address in the specified VPN. If you do not include vpn-instance vpn-instance-name in this command, the command removes the symmetric-passive peer with the IP address of ip-address in the public network.

source
interface-type interface-number
: Specifies the source interface for NTP messages. In an NTP
message the local device sends to its peer, the source IP address is the primary IP address of this interface.
The
interface-type interface-number
argument represents the interface type and number.
version
number
: Specifies the NTP version, where
number
is in the range of 1 to 4. The default value is
4.
Usage guidelines
When you specify a passive peer for the device, the device and its passive peer can be synchronized to
each other. If their clocks are in synchronized state, the clock with a high stratum level is synchronized to
the clock with a lower stratum level.
To synchronize the PE to a PE or CE in a VPN, provide
vpn-instance
vpn-instance-name
in your
command.
If you include
vpn-instance
vpn-instance-name
in the
undo ntp-service unicast-peer
command, the
command removes the symmetric-passive peer with the IP address of
ip-address
in the specified VPN. If
you do not include
vpn-instance
vpn-instance-name
in this command, the command removes the
symmetric-passive peer with the IP address of
ip-address
in the public network.
Examples
# Specify the device with the IP address of 10.1.1.1 as the symmetric-passive peer of the device, configure
the device to run NTP version 4, and specify the source interface of NTP messages as VLAN-interface 1.
<Sysname> system-view
