Network requirements
As shown in
client mode, and uses Device A as the NTP server. Configure NTP authentication on Device A and Switch
B.
Figure 49 Network diagram
Description
Display the synchronization status of the system clock.
Set the source interface for an NTP message.
If you do not want the IP address of a certain interface on the local device
to become the destination address of response messages, you can specify
the source interface for NTP messages, so that the source IP address in the
NTP messages is the IP address of this interface. If the specified source
interface is down, the source IP address is the IP address of the egress
interface.
Set NTP authentication key.
The NTP authentication feature should be enabled for a system running
NTP in a network where there is a high security demand. This feature
enhances the network security by means of client-server key
authentication, which prohibits a client from synchronizing with a device
that has failed authentication.
You can set two authentication keys, each of which is composed of a key
ID and key string.

Specify the IP address of an NTP server, and configure the authentication
NTP Server
key ID used for the association with the NTP server. Only if the key
1/Reference
provided by the server is the same with the specified key will the device
Key ID
synchronize its time to the NTP server.
You can configure two NTP servers. The clients will choose the optimal
reference source.
NTP Server
2/Reference
The IP address of an NTP server is a unicast address, and cannot be a
Key ID
broadcast or a multicast address, or the IP address of the local clock
source.
Set the time zone for the system.
Figure 49, the local clock of Device A is set as the reference clock. Switch B operates in the
ID—ID of a key.
Key string—A character string for MD5 authentication key.
