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 2

NTP Server
1/Reference
Key ID
Specify the IP address of an NTP server, and configure the
authentication key ID used for the association with the NTP server.
Only if the key provided by the server is the same as the specified
key will the LB module synchronize its time to the NTP server.
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.
