Network requirements
As shown in
and synchronizes the time among multiple devices as follows:
Device C's local clock is to be used as a reference source, with the stratum level of 2.
•
Device C works in broadcast server mode and sends out broadcast messages from VLAN-interface
•
2.
• Device A and Device B work in broadcast client mode, and each listen to broadcast messages
through their VLAN-interface 2.
