Operation Manual – NTP
H3C S9500 Series Routing Switches
clock precision: 2^17
clock offset: 0.0000 ms
root delay: 0.00 ms
root dispersion: 0.00 ms
peer dispersion: 0.00 ms
reference time: 00:00:00.000 UTC Jan 1 1900(00000000.00000000)
After the synchronization, H3C 2 turns into the following status:
[H3C2] display ntp-service status
Clock status: synchronized
Clock stratum: 3
Reference clock ID: 1.0.1.11
Nominal frequency: 60.0002 Hz
Actual frequency: 60.0002 Hz
Clock precision: 2^17
Clock offset: -9.8258 ms
Root delay: 27.10 ms
Root dispersion: 49.29 ms
Peer dispersion: 10.94 ms
Reference time: 19:21:32.287 UTC Oct 24 2004(C5267F3C.49A61E0C)
By this time, H3C 2 has been synchronized by H3C 1 and is at stratum 3, higher than
H3C 1 by 1.
Display the sessions of H3C 2 and you will see H3C 2 has been connected with H3C 1.

1.4.2 NTP Peer Configuration Example

I. Network requirements
On H3C 3, set local clock as the NTP master clock at stratum 2. On H3C 2, configure
H3C 1 as the time server in server mode and set the local equipment as in client mode.
At the same time, H3C 5 sets H3C 4 as its peer. (Note: H3C 3 supports to configure the
local clock as the master clock)
