The output information indicates that S3100-1 is synchronized to Quidway3, with the
clock stratum being 3, one stratum higher than Quidway3.

1.7.5 NTP Server Mode with Authentication Configuration
I. Network requirements
The local clock of Quidway1 operates as the master NTP clock, with the clock stratum
set to 2.
An S3100 series switch operates in client mode with Quidway1 as the time server.
Quidway1 operates in the server mode automatically. Meanwhile, NTP authentication
is enabled on both sides.
Note:
This example assumes that Quidway1 is a switch that supports the local clock being
the master NTP clock.
