Configuring Ntp Authentication - Huawei Quidway S3100 Series Operation Manual

Operation Manual – NTP
Quidway S3100 Series Ethernet Switches
If the NTP authentication is not enabled on a client, the client can be synchronized
to a server regardless of the NTP authentication configuration performed on the
server (assuming that the related configurations are performed).
You need to couple the NTP authentication with a trusted key.
The configurations performed on the server and the client must be the same.
A client with NTP authentication enabled is only synchronized to a server that can
provide a trusted key.

with the corresponding NTP
server on the client.
You can associate the NTP
server with the authentication
key while configuring the
switch to operate in a specific
unicast-peer
NTP mode. You can also
associate them using this
command after configuring
the NTP mode where the
switch is to operate in.
