1080 CHAPTER 85: NTP CONFIGURATION
[SwitchC] interface vlan-interface 2
[SwitchC-Vlan-interface2] ntp-service broadcast-server
2 Configuration on Switch D:
# Enter system view.
<SwitchD> system-view
# Enter VLAN-interface 2 view.
[SwitchD] interface vlan-interface 2
# Specify Switch D as the broadcast client.
[SwitchD-Vlan-interface2] ntp-service broadcast-client
3 Configuration on Switch A:
# Enter system view.
<SwitchA> system-view
# Enter VLAN-interface 3 view
[SwitchA] interface vlan-interface 3
# Specify Switch A as the broadcast client.
[SwitchA-Vlan-interface3] ntp-service broadcast-client
Because Switch A and Switch C are on different subnets, Switch A cannot receive
the broadcast messages from Switch C Switch D gets synchronized upon receiving
a broadcast message from Switch C.
# View the NTP status of Switch D after clock synchronization.
[SwitchD] display ntp-service status
Clock status: synchronized
Clock stratum: 3
Reference clock ID: 3.0.1.31
Nominal frequency: 64.0000 Hz
Actual frequency: 64.0000 Hz
Clock precision: 2^7
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)
As shown above, Switch D has been synchronized to Switch A, and the clock
stratum level of Switch D is 3, while that of Switch C is 2.
# View the NTP session information of Switch D, which shows that an association
has been set up between Switch D and Switch C.
