cisco设备的NTP客户端设置(国外英文资料) NTP client settings for Cisco devices -------------------------------------------------------------------------------- Commands and definitions that need to be used in the NTP configuration of Cisco network systems: NTP access-group: this global command is used for the access control of the router N T P service. NTP authenticate: is a global command that enables N T P authentication. NTP authentication-key: the global command is used to define the key values for N T P authentication. NTP broadcast: is an interface command that specifies a specific interface to send N T P broadcast packets. NTP broadcast client: is an interface command that enables routers to receive N T P broadcast packets through a specific interface. The NTP broadcast delay: is a global command that sets the estimated value of the backhaul time between packets and between the router and the N T P server. The global command for NTP clock-period: does not have to be entered. When the system clock is synchronized using N T P, the router automatically generates this command. NTP disable: this interface command prevents N T P packets from being accepted by a particular interface. NTP master: this global command is used to configure the router as the N T P master clock, only if there are no external N T P sources available, or for testing purposes. NTP peer: the global command synchronizes the system clock of the router to its peer clock (or synchronizes the clock of the peer). NTP server: this global command synchronizes the system clock of the router to the time server. NTP source: the global command forces the router to use a specific source address in its N T P package. NTP trusted-key: this global command is used to verify the specific authentication key of the router. NTP update-calendar: this global command enables N T P to periodically update the calendar of the Cisco 7XXX series routers. Show NTP status: is an execution mode command that displays the N T P information
