1.8.6 Configuring NTP Broadcast Mode with Authentication

I. Network requirements
Switch C's local clock is to be used as a reference source, with the stratum level of
3.
Switch C works in the broadcast server mode and sends out broadcast messages
from VLAN-interface 2.
Switch D works in the broadcast client mode and receives broadcast messages
through VLAN-interface 2.
NTP authentication is enabled on both Switch C and Switch D.
