Usage Guidelines

Usage Scenario

Configure the local source interface for sending/receiving NTP packets, so that the IP address of another interface on the device cannot be used as the destination address of a reply packet, which is convenient for a user to subsequently deploy a flow control policy. If the interface is not specified, the source IP address of the NTP packets is selected according to the route.


In the broadcast mode, the NTP service is performed on a specific interface, that is, the source interface. Therefore, the ntp-service source-interface command is invalid for the broadcast mode.


# Specify VLANIF100 as the source interface to send all the NTP packets.
