Command Reference Guide – NTP Chapter 1 NTP Configuration Commands
1-14
Use the undo ntp-service source-interface command to cancel the current setting.
By default, the source address depends on the output interface.
You can use this command to designate an interface of which the IP address will be
the source IP address in all the NTP packets sent by the local device so that the
remote device sends the response message to this interface only.
Example
# Configure all the outgoing NTP packets to use the IP address of Vlan-Interface1 as
their source IP address.
