# Display the NTP status of Device A after clock synchronization.
[DeviceA-Vlan-interface3] display ntp-service status
Clock status: synchronized
Clock stratum: 3
Reference clock ID: 3.0.1.31
Nominal frequency: 64.0000 Hz
Actual frequency: 64.0000 Hz
Clock precision: 2^7
Clock offset: 0.0000 ms
Root delay: 40.00 ms
Root dispersion: 10.83 ms
Peer dispersion: 34.30 ms
Reference time: 16:02:49.713 UTC Sep 19 2005 (C6D95F6F.B6872B02)
The output shows that Device A has synchronized to Device C because it has a higher stratum than
Device C.
# Display NTP session information for Device A.
[DeviceA-Vlan-interface3] display ntp-service sessions
