R211x-HP Flexfabric 11900 Network Management and Monitoring Configuration Guide

Configuration procedure

1. Set the IP address for each interface as shown in Figure 10. (Details not shown.)

2. 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

3. Configure Device B:

# Enable the NTP service.

<DeviceB> 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

[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

Clock status: synchronized

Clock stratum: 3

System peer: 3000::34

Local mode: client

Reference clock ID: 163.29.247.19

Leap indicator: 00

Clock jitter: 0.000977 s

Stability: 0.000 pps

Clock precision: 2^-10

Root delay: 0.02649 ms

Root dispersion: 12.24641 ms

Reference time: d0c60419.9952fb3e Wed, Dec 29 2010 19:01:45.598

The output shows that Device B has been synchronized to Device A, the clock stratum level of

Device B is 3, and that of Device A is 2.

# Display IPv6 NTP association information for Device B.

[DeviceB] display ntp-service ipv6 sessions

Notes: 1 source(master), 2 source(peer), 3 selected, 4 candidate, 5 configured.

Source: [12345]3000::34

Reference: 127.127.1.0 Clock stratum: 2

Reachabilities: 15 Poll interval: 64

Last receive time: 19 Offset: 0.0

Roundtrip delay: 0.0 Dispersion: 0.0

Total sessions : 1

The output shows that an association has been set up between Device B and Device A.
