Item Description
Key 1
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.
• ID is the ID of a key.
• Key string is a character string for MD5 authentication key.

Key ID
Specify the IP address of an NTP server, and configure the
authentication key ID used for the association with the NTP server. The
device synchronizes its time to the NTP server only if the key provided
by the server is the same with the specified key.
You can configure two NTP servers. The clients will choose the optimal
reference source.
IMPORTANT:
The IP address of an NTP server is a unicast address, and cannot
be a broadcast or a multicast address, or the IP address of the
local clock source.
