interface-number: Specifies an interface along with interface-type.
Description
Use the ntp-service source-interface command to specify an interface for the local
end to transmit NTP messages.
Use the undo ntp-service source-interface command to cancel the setting.
Normally, the source IP address of an NTP message is the address of its output
interface. However, you may use this command to specify the source IP address for all
the NTP messages to be transmitted. The replies to these messages, as a result, use
that address as their destination address.
Example
# Use the IP address of interface Ethernet 1/0/0 as the source address of all the NTP
messages to be transmitted.
[3com] ntp-service source-interface ethernet 1/0/0
