NTP configuration examples

NTP client/server mode configuration example

Network requirements

Perform the following configurations to synchronize the time between Device B and Device A:

• As shown in Figure 17, the loc

al clock of Device A is to be used as a reference source, with the

stratum level 2.

• Device B operates in client/server mode and Device A is to be used as the NTP server of Device B.

Configuration procedure

1. Set the IP address for each interface as shown in Figure 17. (Details not shown.)

2. Configure Device A:

# Specify the local clock as the reference source, with the stratum level 2.

<DeviceA> system-view

[DeviceA] ntp-service refclock-master 2

3. 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

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 that Device B synchronizes to Device A.

<DeviceB> system-view

[DeviceB] ntp-service unicast-server 1.0.1.11

# Display the NTP status of Device B after clock synchronization.

[DeviceB] display ntp-service status

Clock status: synchronized
