NTP Implementation Mode Configuration 757NTP ImplementationMode ConfigurationA switch can operate in the following NTP modes:■ NTP client mode■ NTP server mode■ NTP peer mode■ NTP broadcast server mode■ NTP broadcast client mode■ NTP multicast server mode■ NTP multicast client modePrerequisites When a Switch 7750 operates in NTP server mode or NTP peer mode, you need toperform configuration on the client or the active peer only. When a Switch 7750operates in NTP broadcast mode or NTP multicast mode, you need to performconfigurations on both the server side and the client side.Configuring NTPImplementation ModesBroadcast mode ■ Configure the Switch 7750 to operate in NTPbroadcast server mode. In this case, the Switch7750 broadcasts NTP packets through theVLAN interface configured on the switch.■ Configure the Switch 7750 to operate in NTPbroadcast client mode. In this case, the Switch7750 receives broadcast NTP packets throughthe VLAN interface configured on the switch.Multicast mode ■ Configure the Switch 7750 to operate in NTPmulticast server mode. In this case, the Switch7750 sends multicast NTP packets through theVLAN interface configure on the switch.■ Configure the Switch 7750 to operate in NTPmulticast client mode. In this case, the Switch7750 receives multicast NTP packets throughthe VLAN interface configure on the switch.Table 601 NTP implementation modes on a Switch 7750NTP implementation mode Configuration on Switch 7750Table 602 Configure NTP implementation modesOperation Command DescriptionEnter system view system-view -Configure to operatein the NTP clientmodentp-serviceunicast-server { remote-ip |server-name }[ authentication-keyid key-id |priority | source-interfaceinterface -type interface-number |version number ]*OptionalBy default, no Ethernet switchoperates in the NTP client modeConfigure to operatein the NTP peer modentp-serviceunicast-peer { remote-ip |peer-name }[ authentication-keyid key-id |priority | source-interfaceinterface -type interface-number |version number ]*OptionalBy default, no Ethernet switchoperates in the NTP peer mode
