<Huawei> system-view
[Huawei] sysname RouterC
[RouterC] interface
[RouterC-GigabitEthernet1/0/0] ip address 10.0.0.1 24
[RouterC-GigabitEthernet1/0/0] quit
Step 2 Configure the NTP client/server mode.
# Set the local clock of RouterC as the NTP primary clock, and set the clock stratum to 2.
[RouterC] ntp-service refclock-master 2
# Specify on RouterD that RouterC functions as the NTP server of RouterD.
<RouterD> system-view
[RouterD] ntp-service unicast-server 10.0.0.1
After the preceding configuration is complete, RouterD can synchronize its clock with the clock
of RouterC.
# Check the NTP status of RouterD, and you can find that the clock status is "synchronized",
indicating that the synchronization is complete. The stratum of the clock is 3, which is one
stratum lower than that of the clock of RouterC.
[RouterD] display ntp-service status
clock status: synchronized
clock stratum: 3
reference clock ID: 10.0.0.1
nominal frequency: 64.0029 Hz
actual frequency: 64.0029 Hz
clock precision: 2^7
clock offset: 0.0000 ms
root delay: 62.50 ms
root dispersion: 0.20 ms
peer dispersion: 7.81 ms
reference time: 06:52:33.465 UTC Mar 7 2012(C7B7AC31.773E89A8)
Step 3 Configure the NTP unicast symmetric peer mode.
# Specify on RouterE that RouterD functions as the symmetric passive peer of RouterE.
<RouterE> system-view
[RouterE] ntp-service unicast-peer 10.0.0.2
RouterE is not configured with a primary clock and its clock stratum is lower than that of
RouterD, so that RouterE synchronizes its clock with the clock of RouterD.
Step 4 Verify the configuration.
Monitor the status of RouterE after the synchronization.RouterThe clock of RouterE is in
"synchronized" status, indicating that the synchronization is complete. The clock stratum of
RouterE is 4, which is one stratum lower than that of the symmetric passive peer RouterD.
# Check the clock status of RouterE.
[RouterE] display ntp-service status
clock status: synchronized
clock stratum: 4
reference clock ID: 10.0.0.2
nominal frequency: 64.0029 Hz
actual frequency: 64.0029 Hz
clock precision: 2^7
clock offset: 0.0000 ms
root delay: 124.98 ms
root dispersion: 0.15 ms
