Item Description
Clock status Display the synchronization status of the system clock.
Source Interface
Set the source interface for an NTP message.
If you do not want the IP address of a certain interface on the local device
to become the destination address of response messages, specify the
source interface for NTP messages. This makes the source IP address in the
NTP messages the primary IP address of this interface. If the specified
source interface is down, the source IP address is the primary IP address of
the egress interface.
Key 1 Set NTP authentication key.
Enable the NTP authentication feature for a system running NTP in a
network where there is a high security demand. This feature improves the
network security by means of client-server key authentication. This
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..

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 as 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.
