414 CHAPTER 12: USING SYSTEM MANAGEMENT COMMANDS
Use the undo ntp-service source-interface command to remove the
configuration.
If you do not want the IP addresses of the other interfaces on the local device to
be the destination addresses of response messages, you can use this command to
specify a specific interface to send all NTP packets. In this way, the IP address of
the interface is the source IP address of all NTP messages sent by the local device.
Example
Specify the source IP addresses of all sent NTP messages as the IP address of
Vla-interface1.
