The above output information indicates that the S5600 series switch is synchronized to
H3C1, and the stratum of its clock is 3, one stratum higher than H3C1.

1.7.2 NTP Peer Mode Configuration

I. Network requirements
H3C2 sets the local clock to be the NTP master clock, with the clock stratum being 2.
Configure an S5600 series switch to operate as a client, with H3C2 as the time server.
H3C2 will then operate in the server mode automatically. Meanwhile, H3C3 sets the
S5600 series switch to be its peer.
Note:
This example assumes that:
H3C2 is a switch that allows its local clock to be the master clock.
H3C3 is a switch that allows its local clock to be the master clock and the stratum of
its clock is 1.
