// 配置接口IP，以实现与NTP服务器通信

SW#

SW#conf t

SW(config)#int f0/0

SW(config-if)#ip add 192.168.0.69 255.255.255.0

SW(config-if)#no shutdown

SW(config-if)#end

SW#

// 配置NTP Client，并指定NTP服务器

SW#

SW#conf t

SW(config)#service timestamps log datetime localtime

SW(config)#service timestamps debug datetime localtime

SW(config)#ntp server 192.168.0.168

SW(config)#ntp update-calendar // 如果有硬件时钟，同步设备硬件时钟

SW(config)#end

SW#

// 查询同步结果，已经实现了同步
