Configuring NTP Symmetric Peer Mode

Network requirements
As shown in
stratum level of 2.
Device C (a WX3000 series device) uses Device A as the NTP server, and Device A works in
server mode automatically.
The local clock of Device B is set as the NTP master clock, with the clock stratum level of 1. Set
Device C as the peer of Device B.

Device B
Configuration procedure
1) Configure Device C.
# Set Device A as the NTP server.
<DeviceC> system-view
[DeviceC] ntp-service unicast-server 3.0.1.31
2) Configure Device B (after the Device C is synchronized to Device A).
# Enter system view.
<DeviceB> system-view
# Set Device C as the peer of Device B.
[DeviceB] ntp-service unicast-peer 3.0.1.33
Device C and Device B are symmetric peers after the above configuration. Device B works in symmetric
active mode, while Device C works in symmetric passive mode. Because the stratum level of the local
clock of Device B is 1, and that of Device C is 3, the clock of Device C is synchronized to that of Device
B.
View the status of Device C after the clock synchronization.
