ntp-service source
Use
ntp-service source
to specify a source IPv4 address for NTP messages.

undo ntp-service source
to restore the default.
Syntax
ntp-service source
{
interface-type interface-number
|
ipv4-address
}
undo ntp-service source
Default
No source IPv4 address is specified for NTP messages. The device performs the following
operations:
•
Searches the routing table for the outbound interface of NTP messages.
•
Uses the primary IPv4 address of the outbound interface as the source IPv4 address for NTP
messages.
Views
System view
Predefined user roles

Parameters
interface-type interface-number
: Specifies an interface by its type and number. If you
specify a source interface for NTP messages, the device uses the primary IPv4 address of the
specified source interface as the source address to send NTP messages. The receiving device uses
this address as the destination address of the NTP response message.
ip-address
: Specifies the source IPv4 address for NTP messages.
Usage guidelines
When the device responds to an NTP request, the source IP address of the NTP response is always
the IP address of the interface that has received the NTP request.
If you have specified the source interface for NTP messages in the
ntp-service unicast-server
or
ntp-service unicast-peer
command, the IPv4 address of the specified interface is used as the
source IPv4 address for NTP messages.
If you have configured the
ntp-service
broadcast-server
or
ntp-service multicast-server
command in an interface view, the IPv4 address of the interface is used as the source IPv4 address
for broadcast or multicast NTP messages.
If the specified source interface is down, the device does not send NTP messages.
Examples
# Specify the IP address of VLAN-interface 1 as the source IPv4 address for NTP messages.
<Sysname> system-view
[Sysname] ntp-service source vlan-interface 1
