Ipv6 Ntp Multicast Mode Configuration Example - HP 5920 Configuration Manual

[SwitchA-Vlan-interface3] ntp-service multicast-client
7. Verify the configuration:
# Display the NTP status of Switch A after clock synchronization.
[SwitchA-Vlan-interface3] display ntp-service status
Clock status: synchronized
Clock stratum: 3
System peer: 3.0.1.31
Local mode: bclient
Reference clock ID: 3.0.1.31
Leap indicator: 00
Clock jitter: 0.165741 s
Stability: 0.000 pps
Clock precision: 2^-10
Root delay: 0.00534 ms
Root dispersion: 4.51282 ms
Reference time: d0c61289.10b1193f
The output shows that Switch A has been synchronized to Switch C, the clock stratum level of
Switch A is 3, and that of Switch C is 2.
# Display IPv4 NTP association information for Switch A.
[SwitchA-Vlan-interface3] display ntp-service sessions
********************************************************************************
[1234]3.0.1.31
Notes: 1 source(master),2 source(peer),3 selected,4 candidate,5 configured.
Total sessions : 1
The output shows that an association has been set up between Switch A and Switch C.

IPv6 NTP multicast mode configuration example

Network requirements
As shown in
segments and synchronizes the time among multiple devices.
• Switch C's local clock is to be used as a reference source, with the stratum level 2.
Switch C operates in IPv6 multicast server mode and sends out IPv6 multicast messages from
•
VLAN-interface 2.
Switch A and Switch D operate in IPv6 multicast client mode and receive IPv6 multicast messages
•
through VLAN-interface 3 and VLAN-interface 2, respectively.
