1.7.5 Configuring NTP Server Mode with Authentication

I. Network requirements
The local clock of H3C1 is set to the NTP master clock, with a clock stratum level of 2.
An S3600 Ethernet switch considers H3C1 as the NTP server and operates in client
mode, while H3C1 operates in server mode automatically. In addition, the NTP
authentication function is enabled on both sides.
Note:
This example assumes that H3C1 is a switch that supports the local clock being the
NTP master clock.
