将核心交换机配置为NTP服务器
AR配置外源NTP
1.配置ntp
<XQ-R1220>sys
[XQ-R1220]ntp-service unicast-server 120.25.115.20 #阿里云ntp
[XQ-R1220]ntp-service unicast-server 203.107.6.88 #阿里云ntp
2.查看ntp状态
<XQ-R1220>display ntp status
clock status: synchronized
clock stratum: 3
reference clock ID: 203.107.6.88
nominal frequency: 100.0000 Hz
actual frequency: 100.0000 Hz
clock precision: 2^12
clock offset: 1.0987 ms
root delay: 54.33 ms
root dispersion: 40.58 ms
peer dispersion: 0.81 ms
reference time: 07:51:25.923 UTC Sep 27 2022(E6DD29FD.EC5B39E2)
核心交换机配置ntp服务
<XQ-S5731>sys
[XQ-S5731]undo ntp server disable #启用ntp server
[XQ-S5731]ntp refclock-master 3 #设置本地设备时钟作为NTP主时钟,层数为3。
[XQ-S5731]display ntp status
clock status: synchronized
