Configuration procedure
1.
Set the IP address for each interface, and make sure Device A and Device B can reach each
other, as shown in
2.
Configure Device A:
# Enable the NTP service.
<DeviceA> system-view
[DeviceA] ntp-service enable
# Specify the local clock as the reference source, with the stratum level 2.
[DeviceA] ntp-service refclock-master 2
3.
Configure Device B:
# Enable the NTP service.
<DeviceB> system-view
[DeviceB] ntp-service enable
# Enable NTP authentication on Device B.
[DeviceB] ntp-service authentication enable
# Set an authentication key, and input the key in plain text.
[DeviceB] ntp-service authentication-keyid 42 authentication-mode md5 simple
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, and associate the server with key 42.
[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.
4.
Configure NTP authentication on Device A:
# Enable NTP authentication.
[DeviceA] ntp-service authentication enable
# Set an authentication key, and input the key in plain text.
[DeviceA] ntp-service authentication-keyid 42 authentication-mode md5 simple
aNiceKey
# Specify the key as a trusted key.
[DeviceA] ntp-service reliable authentication-keyid 42
5.
Verify the configuration:
# Verify that Device B has synchronized to Device A, and the clock stratum level is 3 on Device
B and 2 on Device A.
