Parameter
interface-name: Interface name. The IP address of the interface will be used as the
source IP address of the messages.
interface-type: Interface type, which identifies an interface along with
interface-number.
interface-number: Interface number, which identifies an interface along with
interface-type.
Description
Using the ntp-service source-interface command, you can specify a local interface
for NTP message transmission. Using the undo ntp-service source-interface
command, you can remove the current setting.
Source address will be determined depending on the output interface.
Using this command, you can specify a source IP address to be carried by all the
transmitted NTP messages by specifying the interface. This command is useful in the
case that you do not want the IP addresses of any other local interfaces to be the
destination addresses for receiving the response messages except for the specified
one.
Example
Specify the interface Ethernet 0 so that its IP address can be used as the source IP
address carried by all the outbound NTP message packets.
