HP 5820X Switch Configuration Manual page 80

Clock status: synchronized
Clock stratum: 3
Reference clock ID: 3.0.1.31
Nominal frequency: 100.0000 Hz
Actual frequency: 100.0000 Hz
Clock precision: 2^18
Clock offset: -21.1982 ms
Root delay: 15.00 ms
Root dispersion: 775.15 ms
Peer dispersion: 34.29 ms
Reference time: 15:22:47.083 UTC Sep 19 2005 (C6D95647.153F7CED)
The output shows that Switch B has been synchronized to Switch A, and the clock stratum level of Switch B
is 3.
Configuration on Switch C (after Switch B is synchronized to Switch A):
4.
# Configure Switch C as a symmetric peer after local synchronization.
[SwitchC] ntp-service unicast-peer 3.0.1.32
The output shows that Switch B and Switch C are configured as symmetric peers, with Switch C in the
symmetric-active mode and Switch B in the symmetric-passive mode. Because the stratus level of Switch C
is 16 while that of Switch B is 3, Switch B is synchronized to Switch C.
# View the NTP status of Switch C after clock synchronization.

The output shows that Switch C has been synchronized to Switch B and the clock stratum level of Switch C
is 4.
# View the NTP session information of Switch C, which shows that an association has been set up
between Switch B and Switch C.
