Example: Configuring NTP Multicast Mode
SW77503 sets the local clock as the master clock at stratum 2, and multicast
packets from Vlan-interface2. Set SW77504 and SW77501 to receive multicast
messages from their respective Vlan-interface2. See
Figure 66.
Configure Ethernet Switch SW77503:
1 Enter system view.
<SW77503>system-view
2 # Set the local clock as a master NTP clock at stratum 2.
