Configuration procedure
1
Configuration on Device A:
# Specify the local clock as the reference source, with the stratum level of 2.
<DeviceA> system-view
[DeviceA] ntp-service refclock-master 2
2
Configuration on Device B:
# View the NTP status of Device B before clock synchronization.
<DeviceB> display ntp-service status
Clock status: unsynchronized
Clock stratum: 16
