z 

A multicast server can synchronize broadcast clients only after its clock has been synchronized. 

z 

You can configure up to 254 multicast clients, among which 128 can take effect at the same time. 

 

A network device can get its clock synchronized in one of the following two ways: 

z 

Synchronized to the local clock, which works as the reference source. 

z 

Synchronized to another device on the network in any of the four NTP operation modes previously 

described. 

If you configure two synchronization modes, the device will choose the optimal clock as the reference 

source. 

Follow these steps to configure the local clock as a reference source:
