3.6.3 Example for Configuring NTP Authentication in Broadcast
Mode
Networking Requirements
As shown in Figure 3-4,
l Switch C and Switch D are on the same network segment; Switch A is on another network
segment; Switch F connects the two network segments.
l As the NTP broadcast server, Switch C uses the local clock as the NTP master clock, which
is a stratum-3 clock. Switch C sends broadcast packets through VLANIF10, namely,
GE1/0/0.
l Switch D uses VLANIF10, namely, GE1/0/0, to listen to the broadcast packets.
l Switch A uses VLANIF20, namely, GE1/0/0, to listen to the broadcast packets.
l NTP authentication needs to be enabled.

Configuration Roadmap
The configuration roadmap is as follows:
1. Configure Switch C as the NTP broadcast server.
2. Configure Switch A and Switch D as the NTP broadcast clients.
3. Configure NTP authentication on Switch A, Switch C, and Switch D.
Data Preparation
To complete the configuration, you need the following data:
