1.7.4 NTP Multicast Mode Configuration

I. Network requirements

H3C3 sets the local clock to be NTP master clock, with the clock stratum of 2. It

advertises multicast packets through VLAN interface 2.

Configure S7500-1 and S7500-2 to listen to multicast packets through their VLAN

interface 2.

This example assumes that H3C3 is a switch that supports the local clock being the

master clock.
