S5130系列NTP配置时间同步不成功。

在局域网中搭建了一台windows server 2016的服务器作为NTP服务器，交换机与该服务器路由可达。交换机中配置

<h3c>dis cu | in ntp 

 ntp-service source Vlan-interface10 

 ntp-service unicast-server 192.168.10.182

———————————————————————————————

然后

<h3c>display ntp-service status 

 Clock status: unsynchronized 

 Clock stratum: 16 Reference clock ID: none

 Clock jitter: 0.000000 s
