1.7.3 NTP Broadcast Mode Configuration

I. Network requirements
Quidway3 sets its local clock to be an NTP master clock, with the stratum being 2. NTP
packets are broadcast through VLAN interface 2.
Configure S3900-1 and S3900-2 to listen broadcast packets through their VLAN
interface 2.
Note:
This example assumes that Quidway3 is a switch that supports the local clock being the
master clock.
