Step Command Remarks
2. Specify the source interface
for NTP message.
ntp-service source-interface
interface-type interface-number
By default, no source interface is
specified for NTP messages, and

the interface determined by the

address of NTP messages.
CAUTION:
•
If you have specified the source interface for NTP messages in the ntp-service unicast-server or
ntp-service unicast-peer command, the interface specified in the ntp-service unicast-server or

• If you have configured the ntp-service broadcast-server or ntp-service multicast-server command, the

• If the specified source interface for NTP messages is down, the source IP address for an NTP message
that is sent out is the primary IP address of the outgoing interface of the NTP message.
