510 CHAPTER 12: USING SYSTEM MANAGEMENT COMMANDS View System view Parameter interface-name : Specify an interface. The source IP address of the packets will be taken from the address of the interface. interface-type : Specify the interface type and determine an interface with the interface-number parameter. interface-number : Specify the interface number and determine an interface with the interface-type parameter. Description Use the ntp-service source-interface command to designate an interface to transmit NTP message. Use the undo ntp-service source-interface command to cancel the current setting. The source address specifies where the packets are transmitted from. You can use this command to designate an interface to transmit all the NTP packets and take the source address of these packets from its IP address. If you do not want any other interface to receive the acknowledgement packets, use this command to specify one interface to send all the NTP packets. Example Configure all the outgoing NTP packets to use the IP address of Vlan-Interface1 as their source IP address. system-view System View: return to User View with Ctrl+Z.
