Figure 284 Network diagram for NTP symmetric peers mode configuration
Configuration procedure
1 Configuration on Switch A:
# Specify the local clock as the reference source, with the stratum level of 2.
<SwitchA> system-view
[SwitchA] ntp-service refclock-master 2
2 Configuration on Switch B:
# Specify Switch A as the NTP server of Switch B.
<SwitchB> system-view
[SwitchB] ntp-service unicast-server 3.0.1.31
3 Configuration on Switch C (after Switch B is synchronized to Switch A):
# Specify the local clock as the reference source, with the stratum level of 1.
<SwitchC> system-view
[SwitchC] ntp-service refclock-master 1
# Configure Switch B as a symmetric peer after local synchronization.
[SwitchC] ntp-service unicast-peer 3.0.1.32
In the step above, Switch B and Switch C are configured as symmetric peers, with
Switch C in the symmetric-active mode and Switch B in the symmetric-passive
mode. Because the stratus level of Switch C is 1 while that of Switch B is 3, Switch
B is synchronized to Switch C.
# View the NTP status of Switch B after clock synchronization.
