Note:
When the switch receives an NTP packet with authentication information, there are
the following scenarios:
If the switch enables NTP authentication, it performs authentication operation.
If the switch does not enable NTP authentication, it regards that the packet has
passed authentication and performs subsequent processing.
When the switch receives an NTP packet without authentication information, there are
the following scenarios:
If the switch enables NTP authentication, it regards the packet an invalid packet
and discards the packet.
If the switch does not enable NTP authentication, it does not perform
authentication processing for the packet.
When the switch receive an NTP packet from a static peer, for example, unicast client,
broadcast/multicast server or active peer entity, the switch performs packet
authentication based on both of the following two conditions:
Global NTP service authentication is enabled by the ntp-service authentication
enable command.
NTP connection authentication is implemented by key binding with peer entity.
