Use the ntp-service source-interface command to specify an interface for sending NTP messages.  

Use the undo ntp-service source-interface command to remove the configured interface for sending 

NTP messages.  

If you do not wish the IP address of a certain interface on the local device to become the destination 

address of response messages, you can use this command to specify a particular interface for sending 

all NTP messages, so that the source address in all NTP messages is the primary IP address of this 

interface.  

# Specify that all NTP messages are to be sent out from VLAN-interface 1.

vpn-instance vpn-instance-name: Specifies a VPN instance by its name, where vpn-instance-name is 

a string of 1 to 31 characters.  

ip-address: IP address of the symmetric-passive peer. It must be a host address, rather than a 

broadcast address, a multicast address or the IP address of the local clock.  

peer-name: Host name of the symmetric-passive peer, a string of 1 to 20 characters.  

authentication-keyid keyid: Specifies the key ID to be used for sending NTP messages to the peer, 

where keyid is in the range of 1 to 4294967295.  

priority: Specifies the peer designated by ip-address or peer-name as the first choice under the same 

condition. 

source-interface interface-type interface-number: Specifies an interface for sending 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. interface-type interface-number represents the interface type and number. 

version number: Specifies the NTP version, where number is in the range of 1 to 3 and defaults to 3.  

Use the ntp-service unicast-peer command to designate a symmetric-passive peer for the device.
