Configuring NTP Symmetric Peer Mode

As shown in Figure 1-7, the local clock of Device A is set as the NTP master clock, with the clock 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.

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.
