The local clock of a Switch 5500, 5500G, or 4210 cannot be set as a reference 
clock. It can synchronize other devices as a reference clock only when its clock is 
synchronized.

■

The local clock of Device C is to be used as a reference source, with the stratum 
level of 2. Set Device C to work in the broadcast server mode and send 
broadcasts through its VLAN-interface 2.

■

Device A and Device D are two Switch 5500s. Set Device A and Device D to 
work in the broadcast client mode and listen to broadcasts through their 
VLAN-interface 2 respectively.
