Ipv6 Ntp Symmetric Active/Passive Mode Configuration Example - HPE FlexFabric 5700 Series Network Management And Monitoring Configuration Manual

IPv6 NTP symmetric active/passive mode configuration
example
Network requirements
As shown in
•
Configure the local clock of Device A as a reference source, with the stratum level 2.
•
Configure Device A to operate in symmetric-active mode and specify Device B as the IPv6
passive peer of Device A.

Configuration procedure
1. Set the IP address for each interface as shown in
2. Configure Device B:
# Enable the NTP service.
<DeviceB> system-view
[DeviceB] ntp-service enable
3. Configure Device A:
# Enable the NTP service.
<DeviceA> 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
# Configure Device B as an IPv6 symmetric passive peer.
[DeviceA] ntp-service ipv6 unicast-peer 3000::36
4. Verify the configuration:
# Verify that Device B has synchronized to Device A.
[DeviceB] display ntp-service status
Clock status: synchronized
Clock stratum: 3
System peer: 3000::35
Local mode: sym_passive
Reference clock ID: 251.73.79.32
