IPv6 NTP client/server mode configuration
example
Network requirements
As shown in Figure 9 , the local clock of Device A is to be used as a reference source, with the stratum level
2. Device B operates in client mode and Device A is to be used as the IPv6 NTP server for Device B.
Figure 9 Network diagram
Configuration procedure
1. Set the IP address for each interface as shown in Figure 9 . (Details not shown.)
2. Configure Device A:
# Enable the NTP service.
system-view
[DeviceA] ntp-service enable
# Specify the local clock as the reference source, with the stratum level 2.
[DeviceA] ntp-service refclock-master 2
3. Configure Device B:
# Enable the NTP service.
system-view
[DeviceB] ntp-service enable
# Specify Device A as the IPv6 NTP server of Device B so that Device B is synchronized to Device
A.
[DeviceB] ntp-service ipv6 unicast-server 3000::34
4. Verify the configuration:
# Display the NTP status of Device B after clock synchronization.
[DeviceB] display ntp-service status
