Configuring the Local Source Interface for Sending and Receiving NTP Packets

Configuring the Local Source Interface for Sending and Receiving NTP Packets

You can configure a local source interface for sending and receiving NTP packets to prevent the IP addresses of other interfaces on the device becoming the destination address of a reply packet. This facilitates deployment of traffic control policies.

Prerequisites

All configurations of basic NTP functions have been completed.

NOTE:

If the ntp unicast-server or the ntp unicast-peer command specifies the source interface of NTP packets, the specified source interface takes effect.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run ntp [ ipv6 ] source-interface interface-type interface-number [ vpn-instance vpn-instance-name ]

    The local source interface for sending and receiving NTP packets is configured.

    By default, the local source interface for sending and receiving NTP packets is not specified. The source IP address of an NTP packet is selected according to the route.

    In broadcast, manycast and multicast modes, the NTP service is performed on the source interface and the ntp [ ipv6 ] source-interface command does not take effect.

    If the specified NTP source interface is in Down state, the source IP address of a sent NTP packet is the primary IP address of the packet's outbound interface.

  3. Run commit

    The configuration is committed.

Verifying the Configuration

  • Run the display current-configuration | include ntp command to verify the configuration of the local source interface for sending and receiving NTP packets.
