After the synchronization, SW88002 turns into the following status:
[SW88002] 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, SW88002 has been synchronized by SW88001 and is at stratum 3, higher
than SW88001 by 1.
Display the sessions of SW88002 and you will see SW88002 has been connected with
SW88001.

49.4.2 NTP Peer Configuration Example I. Network requirements
On SW88003, set local clock as the NTP master clock at stratum 2. On SW88002,
configure SW88001 as the time server in server mode and set the local equipment as in
client mode. At the same time, SW88005 sets SW88004 as its peer. (Note: SW88003
supports to configure the local clock as the master clock)
