1.7.4 Configuring NTP Multicast Mode
I. Network requirements
The local clock of H3C3 is set to the NTP master clock, with a clock stratum level of 2.
H3C3 advertises multicast packets through Vlan-interface2.
S3600-1 and S3600-2 respectively listen to multicast packets through their own
Vlan-interface2.
 Note:
This example assumes that H3C3 is a switch that supports the local clock being the
master clock.
