Configuring NTP examples
Configuring NTP client/server mode example
Network requirements
Perform the following configurations to synchronize the time between Switch B and Switch A:
• As shown in Figure 25,
the local clock of Switch A is to be used as a reference source, with the
stratum level of 2.
• Switch B works in client/server mode and Switch A is to be used as the NTP server of Switch B.
Figure 25 Network diagram for NTP client/server mode configuration
Configuration procedure
1. Set the IP address for each interface as shown in Figure 25. The configuration procedure is omitted.
2. Configuration on Switch B:
# View the NTP status of Switch B before clock synchronization.
<SwitchB> 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 Switch A as the NTP server of Switch B so that Switch B is synchronized to Switch A.
<SwitchB> system-view
[SwitchB] ntp-service unicast-server 1.0.1.11
# View the NTP status of Switch B after clock synchronization.
[SwitchB] display ntp-service status
Clock status: synchronized
Clock stratum: 3
Reference clock ID: 1.0.1.11
Nominal frequency: 64.0000 Hz
Actual frequency: 64.0000 Hz
Clock precision: 2^7
Clock offset: 0.0000 ms
Root delay: 31.00 ms
