Data Preparation
To complete the configuration, you need the following data:
Issue 03 (2010-09-20)
port hybrid untagged vlan 100
#
ntp-service unicast-peer 3.0.1.32
#

Figure 3-4,
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.
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.
Switch D uses VLANIF10, namely, GE1/0/0, to listen to the broadcast packets.
Switch A uses VLANIF20, namely, GE1/0/0, to listen to the broadcast packets.
NTP authentication needs to be enabled.
GE1/0/0 GE1/0/0
VLANIF20 VLANIF20
1.0.1.11/24
1.0.1.2/24
Configure Switch C as the NTP broadcast server.
Configure Switch A and Switch D as the NTP broadcast clients.
Configure NTP authentication on Switch A, Switch C, and Switch D.
