3 After performing local synchronization, set SW88004 as a peer.
[SW88005]ntp-service unicast-peer 3.0.1.32
The above examples configure SW88004 and SW88005 as peers and configure
SW88005 as in active peer mode and SW88004 in passive peer mode. Since
SW88005 is at stratum 1 and SW88004 is at stratum 3, synchronize SW88004 by
SW88005.
After synchronization, SW88004 status is shown as follows:
[SW88004]display ntp-service status
clock status: synchronized
clock stratum: 8
reference clock ID: LOCAL(0)
nominal frequency: 100.0000 Hz
actual frequency: 100.0000 Hz
clock precision: 2^17
clock offset: 0.0000 ms
root delay: 0.00 ms
root dispersion: 10.94 ms
peer dispersion: 10.00 ms
reference time: 20:54:25.156 UTC Mar 7 2002(C0325201.2811A112)
By this time, SW88004 has been synchronized by SW88005 and it is at stratum 2,
or higher than SW88005 by 1.
