1.7.4 NTP Multicast Mode Configuration
I. Network requirements
Quidway3 sets the local clock to be NTP master clock, with the clock stratum of 2. It
advertises multicast packets through VLAN interface 2.
Configure S3100-1 and S3100-2 to listen multicast packets through their VLAN
interface 2.
Note:
This example assumes that Quidway3 is a switch that supports the local clock being
the master clock.
