Configuration example for NTP client/server mode with
authentication
In this configuration example, either Device A or Device B is the SecPath firewall.
Network requirements
As shown in Figure 54 , perform the following configurations to synchronize the time between Device B
and Device A and ensure network security.
The local clock of Device A is to be configured as a reference source, with the stratum level of 2.
Device B operates in client mode and Device A is to be used as the NTP server of Device B, with Device
B as the client.
NTP authentication is to be enabled on both Device A and Device B.

Configuration procedure
1. Set the IP address for each interface as shown in Figure 54 . (Details not shown.)
2. Configure Device A:
# Specify the local clock as the reference source, with the stratum level of 2.
<DeviceA> system-view
[DeviceA] ntp-service refclock-master 2
3. 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:
