Configuration procedure
1. Set the IP address for each interface as shown in Figure 51 . (Details not shown.)
2. Configure SecPath A:
# Specify the local clock as the reference source, with the stratum level of 2.
<SecPathA> system-view
[SecPathA] ntp-service refclock-master 2
3. Configure SecPath B:
# Specify SecPath A as the NTP server of SecPath B.
<SecPathB> system-view
[SecPathB] ntp-service unicast-server 3.0.1.31
4. Configure SecPath C (after SecPath B is synchronized to SecPath A):
# Specify the local clock as the reference source, with the stratum level of 1.
<SecPathC> system-view
[SecPathC] ntp-service refclock-master 1
# Configure SecPath B as a symmetric peer after local synchronization.
[SecPathC] ntp-service unicast-peer 3.0.1.32
In the step above, SecPath B and SecPath C are configured as symmetric peers, with SecPath C in
the symmetric-active mode and SecPath B in the symmetric-passive mode. Because the stratus level
of SecPath C is 1 while that of SecPath B is 3, SecPath B is synchronized to SecPath C.
# View the NTP status of SecPath B after clock synchronization.
