Configuration procedures
1 Configure Switch 7750.
# Set Switch 7750 2 to be the time server.
<Switch 7750 Family> system-view
[Switch 7750 Family] ntp-service unicast-server 3.0.1.31
2 Configure Switch 7750 3 (after Switch 7750 is synchronized with Switch 7750 2).
# Enter system view.
<SW77503> system-view
[SW77503]
# After the local synchronization, set Switch 7750 to be its peer.
[SW77503] ntp-service unicast-peer 3.0.1.32
The Switch 7750 and Switch 7750 3 are configured to be peers with regard to
each other. Switch 775 3 operates in the active peer mode, while Switch 7750
operates in the passive peer mode. Because the stratum of the local clock of
Switch 7750 3 is 1, and that of the Switch 7750 is 3, the Switch 7750 is
synchronized to Switch 7750 3.
