and Switch A and ensure network security.
The local clock of Switch A is to be configured as a reference source, with the stratum level of 2.
•
Switch B works in client mode and Switch A is to be used as the NTP server of Switch B, with Switch
•
B as the client.
• NTP authentication is to be enabled on both Switch A and Switch B.

Configuration procedure
Set the IP address for each interface as shown in
1.
Configuration on Switch B:
2.
<SwitchB> system-view
# Enable NTP authentication on Switch B.
[SwitchB] ntp-service authentication enable
# Set an authentication key.
[SwitchB] ntp-service authentication-keyid 42 authentication-mode md5 aNiceKey
# Specify the key as a trusted key.
[SwitchB] ntp-service reliable authentication-keyid 42
# Specify Switch A as the NTP server of Switch B.
[SwitchB] ntp-service unicast-server 1.0.1.11 authentication-keyid 42
Before Switch B can synchronize its clock to that of Switch A, enable NTP authentication for Switch A.
