Figure 27 Network diagram for configuration of NTP client/server mode with authentication
Configuration procedure
1. Set the IP address for each interface as shown in Figure 27. (Details not shown)
2. Configure Device B:
<DeviceB> system-view
# Enable NTP authentication on Device B.
[DeviceB] ntp-service authentication enable
# Set an authentication key.
[DeviceB] ntp-service authentication-keyid 42 authentication-mode md5 aNiceKey
# Specify the key as a trusted key.
[DeviceB] ntp-service reliable authentication-keyid 42
# Specify Device A as the NTP server of Device B.
[DeviceB] ntp-service unicast-server 1.0.1.11 authentication-keyid 42
Before Device B can synchronize its clock to that of Device A, enable NTP authentication for Device A.
Perform the following configuration on Device A:
# Enable NTP authentication.
[DeviceA] ntp-service authentication enable
# Set an authentication key.
[DeviceA] ntp-service authentication-keyid 42 authentication-mode md5 aNiceKey
# Specify the key as a trusted key.
[DeviceA] ntp-service reliable authentication-keyid 42
# View the NTP status of Device B after clock synchronization.
[DeviceB] display ntp-service status
Clock status: synchronized
Clock stratum: 3
Reference clock ID: 1.0.1.11
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: 1.05 ms
Peer dispersion: 7.81 ms
Reference time: 14:53:27.371 UTC Sep 19 2005 (C6D94F67.5EF9DB22)
The output shows that Device B has been synchronized to Device A, and the clock stratum level of Device
B is 3, while that of Device A is 2.
# View the NTP session information of Device B, which shows that an association has been set up Device
B and Device A.
[DeviceB] display ntp-service sessions
