Syntax

ntp-service source interface-type interface-number

outbound interface of NTP messages, and uses the primary IP address of the outbound interface as the

source IP address for NTP messages.

interface-type interface-number: Specifies an interface by its type and number.

Usage guidelines

If you specify the source interface for NTP messages, the device sets the source IP address of the NTP

messages as the primary IP address of the specified interface when sending the NTP messages.

When the device responds to an NTP request, the source IP address of the NTP response is always the

IP address of the interface that has received the NTP request.

If you do not want the IP address of an interface on the local device to become the destination address

for response messages, use this command.

• 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

ntp-service unicast-peer command serves as the source interface for NTP messages.

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

the source interface for the broadcast or multicast NTP messages is the interface configured with the

respective command.

• If the specified source interface is down, the device searches the routing table for the outbound

interface, and uses the primary IP address of the outbound interface as the source IP address for

NTP messages.

Examples

# Specify the source interface for NTP messages as VLAN-interface 1.

<Sysname> system-view

[Sysname] ntp-service source vlan-interface 1

ntp-service unicast-peer

Use ntp-service unicast-peer to specify a symmetric-passive peer for the device.

Use undo ntp-service unicast-peer to remove the symmetric-passive peer specified for the device.
