Operation Manual – NTP
Quidway S3100 Series Ethernet Switches
Note:
NTP authentication requires that the authentication keys configured for the server
and the client are the same. Besides, the authentication keys must be trusted keys.
Otherwise, the client cannot be synchronized with the server.
In NTP server mode and NTP peer mode, you need to associate the specified key
with the corresponding NTP server/active peer on the client/passive peer. In these
two modes, multiple servers/active peers may be configured for a client/passive
peer, and a client/passive choose the server/active peer to synchronize to by the
authentication key.
