Peer dispersion: 0.00 ms

Reference time: 00:00:00.000 UTC Jan 1 1900 (00000000.00000000)

# Set Device A as the NTP server of Device B.

<DeviceB> system-view

[DeviceB] ntp-service unicast-server 1.0.1.11

#(After the above configurations, Device B is synchronized to Device A.) View the NTP status of Device B.

[DeviceB] display ntp-service status Clock status: synchronized

Clock stratum: 3

Reference clock ID: 1.0.1.11

Nominal frequency: 60.0002 Hz

Actual frequency: 60.0002 Hz

Clock precision: 2^18

Clock offset: 0.66 ms

Root delay: 27.47 ms
