Configuration procedure
1.
Configure Switch B:
# Specify the local clock as the reference source, with the stratum level 2.
[Switch B] ntp-service refclock-master 2
# Configure Switch B to operate in broadcast server mode and send broadcast messages through
VLAN-interface 2.
[Switch B] interface vlan-interface 2
[Switch B-Vlan-interface2] ntp-service broadcast-server
2.
Configure AP 2:
# Configure AP 2 to operate in broadcast client mode and receive broadcast messages on
VLAN-interface 2.
[AP2] interface vlan-interface 2
[AP2-Vlan-interface2] ntp-service broadcast-client
3.
Configure AP 1:
# Configure AP 1 to operate in broadcast client mode and receive broadcast messages on
VLAN-interface 3.
[AP1] interface vlan-interface 3
[AP1-Vlan-interface3] ntp-service broadcast-client
Because AP 1 and Switch B are not in the same network segment, AP 1 cannot receive broadcast
messages from Switch B. However, AP 2 gets synchronized upon receiving a broadcast message from
Switch B.
# Display the NTP status of AP 2 after clock synchronization.
[AP2-Vlan-interface2] display ntp-service status
