NTP configuration examples
This section provides configuration examples for NTP.
Configuring the client/server mode
Network requirements
As shown in
Figure 11
, configure Device A as a reference source, with the stratum level 2. Configure
Device B to operate in client/server mode and use Device A as its NTP server.

Network diagram
Configuration procedure
1.
Set the IP address for each interface as shown in
Figure 11
. (Details not shown.)
2.
Configure Device B:
# Display the NTP status of Device B before clock synchronization.
<DeviceB> display ntp-service status
Clock status: unsynchronized
Clock stratum: 16
Reference clock ID: none
Nominal frequency: 64.0000 Hz
Actual frequency: 64.0000 Hz
Clock precision: 2^7
Clock offset: 0.0000 ms
Root delay: 0.00 ms
Root dispersion: 0.00 ms
Peer dispersion: 0.00 ms
Reference time: 00:00:00.000 UTC Jan 1 1900 (00000000.00000000)
# Specify Device A as the NTP server of Device B so Device B synchronizes to Device A.
