View

Parameters
interface-type interface-number: Specifies an interface by its interface type and
interface number.
Description
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.
Examples
# Specify that all NTP messages are to be sent out from VLAN-interface 1.
<Sysname> system-view
[Sysname] ntp-service source-interface vlan-interface 1
