[SwitchC-Vlan-interface2] ntp-service broadcast-server authentication-keyid 88
2. Configure the AP:
# Configure NTP authentication.
system-view
[AP] ntp-service authentication enable
[AP] ntp-service authentication-keyid 88 authentication-mode md5 123456
[AP] ntp-service reliable authentication-keyid 88
# Configure the AP to operate in NTP broadcast client mode.
[AP] interface vlan-interface 2
[AP-Vlan-interface2] ntp-service broadcast-client
Now, the AP can receive broadcast messages through VLAN-interface 2, and Switch C can send
broadcast messages through VLAN-interface 2. Upon receiving a broadcast message from Switch C, the
AP synchronizes its clock to that of Switch C.
# Display the NTP status of the AP after clock synchronization.
[AP-Vlan-interface2] display ntp-service status
Clock status: synchronized
Clock stratum: 4
Reference clock ID: 3.0.1.31
Nominal frequency: 100.0000 Hz
Actual frequency: 100.0000 Hz
Clock precision: 2^16
Clock offset: 0.0000 ms
Root delay: 31.00 ms
Root dispersion: 8.31 ms
Peer dispersion: 34.30 ms
Reference time: 16:01:51.713 UTC Sep 19 2005 (C6D95F6F.B6872B02)
The output shows that the AP has been synchronized to Switch C, and the clock stratum level of the AP is
4, while that of Switch C is 3.
# Display NTP session information for the AP, which shows that an association has been set up between
the AP and Switch C.
