Switch C's local clock is to be used as a reference source, with the stratum level 2.
•
Switch C operates in broadcast server mode and sends out broadcast messages from
•
VLAN-interface 2.
Switch A and Switch B operate in broadcast client mode, and listen to broadcast messages through
•
VLAN-interface 2.
